Safety Precautions

DANGER
IntelliRupter PulseCloser Fault Interrupters operate at high voltage. Failure to observe the precautions below will result in serious personal injury or death.
Some of these precautions may differ from your company’s operating procedures and rules. Where a discrepancy exists, follow your company’s operating procedures and rules.

QUALIFIED PERSONS. Access to an IntelliRupter fault interrupter must be restricted only to qualified persons. See the “Qualified Persons” section on.
SAFETY PROCEDURES. Always follow safe operating procedures and rules.
PERSONAL PROTECTIVE EQUIPMENT. Always use suitable protective equipment, such as rubber gloves, rubber mats, hard hats, safety glasses, and flash clothing, in accordance with safe operating procedures and rules.
SAFETY LABELS. Do not remove or obscure any of the “DANGER,” “WARNING,” “CAUTION,” or “NOTICE” labels.
OPERATING MECHANISM AND BASE. IntelliRupter fault interrupters contain fast-moving parts that can severely injure fingers. Do not remove or disassemble operating mechanisms or remove access panels on the IntelliRupter fault interrupter base unless directed to do so by S&C Electric Company.

ENERGIZED COMPONENTS. Always consider all parts live until de-energized, tested, and grounded. The integrated power module contains components that can retain a voltage charge for many days after the IntelliRupter fault interrupter has been de-energized and can derive a static charge when in close proximity to a high-voltage source. Voltage levels can be as high as the peak line-to-ground voltage last applied to the unit. Units energized or installed near energized lines should be considered live until tested and grounded.
GROUNDING. The IntelliRupter fault interrupter base must be connected to a suitable earth ground at the base of the utility pole, or to a suitable building ground for testing, before energizing an IntelliRupter fault interrupter, and at all times when energized.
The ground wire(s) must be bonded to the system neutral, if present. If the system neutral is not present, proper precautions must be taken to ensure the local earth ground, or building ground, cannot be severed or removed.
VACUUM INTERRUPTER POSITION. Always confirm the Open/Close position of each interrupter by visually observing its indicator.
Interrupters, terminal pads, and disconnect blades on disconnect-style models may be energized from either side of the IntelliRupter fault interrupter.
Interrupters, terminal pads, and disconnect blades on disconnect-style models may be energized with the interrupters in any position.

MAINTAINING PROPER CLEARANCE. Always maintain proper clearance from energized components.

Wi-Fi Database Administration

The IntelliRupter fault interrupter Wi-Fi database used by LinkStart v4, LSDBR3.txt is located on the computer at: C:\Users\Public\Public Documents\S&C Electric\LinkStart. Each line in the database contains the serial number, device revision, device name, and the device location. This file is automatically created after the first successful LinkStart Wi-Fi connection is made. See Figure 1.

Entries are automatically added to this database file after successful connection to each unique device. To manually add or edit entries using Windows Notepad, double-click on the line to open the file. Each line represents one IntelliRupter fault interrupter. Enter the serial number first (use the format ## – #######), and follow this entry by a tab or one or more spaces. Enter the Wi-Fi communication module version number, either R0 or R3, followed by a tab or one or more spaces. LinkStart v4 will automatically make correction to the version number in this .txt file during the connection process. Enter the name of the IntelliRupter fault interrupter (no spaces are allowed in the device name) and follow this entry by a tab or one or more spaces. Then, enter the device
location (spaces may be used). The universal access number, as illustrated on the first line in Figure 1, should be the first entry in any database. If it is not present, enter this text line: 00-0000000 R3 Universal Serial Number.

NOTICE
The Wi-Fi database structure was changed in LinkStart Version 4.0.0.x. When the existing IntelliRupter fault interrupter database was created for an earlier version of LinkStart, there was no R3 or R0 version number. If the IntelliRupter fault interrupter still has the factory default security keys, the Wi-Fi connection can be completed by entering the IntelliRupter fault interrupter serial number directly into the Serial Number field in the LinkStart Connect to a Device screen, as shown in Figure 2.

Automatic LSDB. txt File Conversion
Copy and paste the old LSDB file to the ProgramData>S&C Electric>LinkStart folder. When the LinkStart v4 connects to an R3 Communication Module, a new LSDBR3.txt file will be automatically created in that folder and populated with the existing information from the old LSDB file. A new column is created in the file adjacent to the serial number column to display the “R” revision of the communication module. All serial numbers are initially listed as “R3.”
When the LinkStart v4 connects to an IntelliRupter fault interrupter with a serial number that is already in the newly created LSDBR3 file, it always first tries to commu-nicate as though it is an R3 Communication Module. If the IntelliRupter fault interrupter has an R0 module, communication is established and the “R” revision number in the new LSDBR3 .txt file is automatically corrected to display “R0” for that serial number. The universal serial number always remains “R3” because it may connect to any control, first trying R3 and then R0.

Editing the LSDBR3.txt File

Information entered in the LSDBR3.txt file displays in the LinkStart Connect to a Device screen when that serial number connects to its IntelliRupter fault interrupter. See serial number 08-9001122 in Figure 2, This text information is displayed in Figure 3.
To demonstrate automatic correction of a manual text entry, when this LSDBR3.txt file was edited the module type was incorrectly entered as “R0.” After connecting to that Intelli-Rupter fault interrupter the LSDBR3.txt file was automatically corrected to “R3,” as shown in Figure 4

Converting the Existing LSDB.txt File
When the LinkStart software is connected to an IntelliRupter fault interrupter that has an R3 Communication Module, the existing LSDB.txt file on the computer is automatically converted to the new LSDBR3.txt format and a column is added for the communication module type.

Communication Module Version Change

NOTICE
When LinkStart establishes a connection in the LSDBR3 file, it will attempt to try that connection type for approximately 3 to 5 minutes before trying the alternate connection. This is to allow the most efficient reconnect when a module is removed and reinstalled with LinkStart active. If the communication module type is changed from R3 to R0 or R0 to R3, S&C recommends opening the LSDBR3 database file and editing the connection type to reflect the new module type. This will speed up the connection process. As an alternative, the line containing the IntelliRupter fault interrupter serial number may be deleted. However, changing the connection type will produce a faster connection.

Interfaces

Ethernet 1 (To Control Module)
In this panel, the network associated with the communication module local area network (LAN) is defined for devices connecting to physical Ethernet Port 1. See Figure 15. The R3 Communication Module ships with a default IP address of 192.168.1.1 and a Netmask equal to 255.255.255.0.

NOTICE
The R3 Communication Module must be configured for Ethernet IP wiring. See S&C Instruction Sheet 766-526 for more information.

Ethernet 2 (WAN)
This panel defines the IP addressing for the R3 Communication Module’s Ethernet Port 2 and subsequent network linkage and settings respective to the customer’s legacy backhaul WAN network. The default setting is DHCP Enabled.
Note: The use of these fields is for WANs that use Ethernet as a back-haul transport protocol. When serial back-haul networks are used or there is no WAN, this panel will not require entries.

DHCP Client State “On”
No fields require identification. A DHCP request will be initiated by the communication gateway to the WAN’s DHCP server, which will assign an IP address for all data communication over the WAN.

DHCP Client State “Off”
Three fields require identification: Static IP Address, Default Gateway IP Address, and Netmask. The Static IP Address setpoint is the WAN IP address assigned to the R3 Communication Module. The Default Gateway IP Address setpoint is the address of the network device upstream of the R3 Communication Module and determines the destination of DNP3 traffic sent to the SCADA master(s). See Figure 16.

The address entries are automatically verified to ensure they function with the other values entered.

DHCP Server State “On”
When the DHCP client is disabled, the DHCP server can be enabled. This allows the R3 Communication Module to automatically provide an IP address to an attached device, such as a field area network radio. See Figure 17 on.

Wi-Fi
The Wi-Fi panel is comprised of the Enable and Broadcast SSID buttons, and the Static IP Address, Netmask, DHCP Server Start IP Address, DHCP Server End IP Address, DHCP Lease Time (minutes), Network Name (SSID), Authentication Method, WPA2 Encryption, WPA2 Passphrase, Mode, Channel, Width, and Transmit Power (dBm) fields. See Figure 18.

The communication module ships with a default Static IP address of 192.168.101.1, a Netmask equal to 255.255.255.0, a DHCP server Start IP address of 192.168.101.2, a DHCP Server End IP address of 192.168.101.10. See Figure 18. The Broadcast SSID is in the Off position. The Network Name (SSID) setting is factory configured with the IntelliRupter fault interrupter serial number. The default Authentication Method setpoint is WPA2-PSK default.

When the Authentication Method setpoint is in the WPA2-PSK setting, an additional WPA2 Passphrase field displays. Enter the passphrase required to open a Wi-Fi connection with this IntelliRupter fault interrupter serial number. The Wi-Fi Session Timeout field determines the time after which the session will automatically terminate from inactivity through the connections.
The Mode setting selects the preferred Wi-Fi transmission standard (Default: N). The Channel setpoint can be set to a channel with less traffic. The Width setpoint is the channel bandwidth in MHz. This setting is only relevant when 802.11n is chosen for the Mode setting. It will be ignored if 802.11b or 802.11g is selected.

Serial 1 (DB9 Port)
This is the RS-232/DB9 port for connection to the radio’s serial console port. If use of RTS/CTS is required, set the Flow Control setpoint to “NONE.” See Figure 18 on.

Wi-Fi Port Numbers

This section displays three configurable port numbers the R3 Communication Module uses to receive packets via the Wi-Fi interface.
Enter the IntelliLink® software UDP Port number and the Radio Console TCP Port number.

The IntelliLink software UDP port is used to receive local packets from a device attached via Wi-Fi. This port has a valid range of 1024-65535, and a default of 9797.
The LinkStart Keepalive UDP port is used to provide connection information to the LinkStart desktop application on the user’s device. This port has a valid range of 1024-65535 and a default of 8829.
The Radio Console TCP port is used to receive packets from a Wi-Fi device intended to be redirected to the serial console interface of a field area network radio device. These packets are directed through the R3 Communication Module’s DB9 port to the radio device. This port has a valid range of 1024-65535, and a default of 8828.

Note: When modifying any of these port values, the similar configuration settings in the LinkStart desktop application must also be modified. In LinkStart, click on the Tools tab, and then select “TCP/IP Port Options.” Three similar settings must be set to the same values as the port numbers in the R3 Communication Module. In LinkStart, the R3 IntelliLink UDP port corresponds to the communication module’s IntelliLink UDP port, the R3 Keepalive UDP port corresponds to the LinkStart Keepalive UDP port, and the R3 VCOM TCP port corresponds to the Radio Console TCP port.

Security

Remote Web Access
The Remote Web Access toggle button enables Web-user interface access via Ethernet Port 2.
To access the user interface for Wi-Fi Administration through the field area network, set the Remote Web Access setpoint to “on.” See Figure 19.
Note: The Remote Web Access setpoint is not available until the default admin password is changed, and remote access requires the field area network to be routed through the Wi-Fi/GPS module by using the Ethernet wiring configuration.

NOTICE
When a SpeedNet Radio is the field area network radio, the remote Web user’s computer will require an additional setting to be updated to enable Web access. The user must reduce the maximum transmission unit (MTU) size to a value of 500 or less. S&C recommends using an MTU size of 500 for optimal performance. To change the MTU size, use the following command on a Windows 10 machine: netsh interface ipv4 set subinterface “Local Area Connection” mtu=500 store=persistent.

S&C Device Certificate
Under “S&C Device Certificate,” the Web page will display a message indicating whether this R3 Communication Module device has a valid factory-assigned S&C Device Certificate. A valid certificate is required to allow this R3 Communication Module to securely pair with an R3 Control Module and enable faster IntelliLink software local traffic. If the R3 Communication Module has a valid certificate, click on the Download Device Certificate button to retrieve and view the details of the certificate. If the R3 Communication Module does not have a valid certificate, call &C’s Global Support and Monitoring Center at 1-888-762-1100 for additional instructions.

User Roles

The User Roles screen permits adding and editing users and their access privileges. The types of user roles include Admin, Engineer 1, Technician 1, and Viewer. The addition of a user is initiated by clicking on the Add User button. A dialog box appears with the required User, Password, and Confirm Password fields, and a drop-down box to select the user Role setpoint. Clicking on a user entry in the list opens the dialog box to edit information for that user. See Figure 20. The permissions provided to each of the user roles are summarized in Table 1. The Admin Role column is assigned to the system administrator, who is not included in this list and therefore cannot be removed.

Configuring an R3 Communication Module

Configuration

ModuleThe R3 Communication Module is a direct replacement for the R0 communication module. This is the default wiring for the R3 Communication Module. See Figure 24 and Figure 25. To obtain remote access to the Wi-Fi/GPS User Interface the WAN must be routed through the Wi-Fi/GPS module. Doing so will enable remote firmware updates and will be required for some cybersecurity features provided in future releases of the Wi-Fi/GPS firmware. To configure the R3 Communication Module with the alternate wiring needed to route WAN traffic through the Wi-Fi/GPS, follow the steps in S&C Instruction Sheet 766-526, “IntelliRupter® PulseCloser® Fault Interrupter, R3 Communication Module Retrofit and Configuration.”

Interface Pinouts
The RS-232 Radio Maintenance Port of the R3 Communication Module is configured as data-terminal equipment. See Figure 24.

The R3 Communication Module Ethernet ports use RJ-45 connectors with the pinout shown in Figure 25. They are auto-sensing for assignment of transmit and receive lines (no crossover cables required) and auto-negotiate for 10-Mbps or 100-Mbps data rates, as required by the connected device.

SpeedNet™ Radio Use with the R3 Communication Module

To change the MTU size on a Windows computer, open a command prompt in Adminis-trator mode and follow these steps:

STEP 1. Open a Command prompt by typing run in the Windows Search prompt and then type “cmd” in the Open: dialog box. Then, hold the <Ctrl>, <Shift>, and <Enter> keys to run the Command prompt with Administrator access. See Figure 26.
Note: If this is not allowed, the user does not have administrative rights to the computer and will be unable to change the MTU as needed.

STEP 2. In the Command prompt, type “ipconfig” and look for the communication adapter/interface to be used to connect to the R3 Communication Module remotely. Typically, this will be one of the Ethernet adapters or a wireless local area connection adapter. See Figure 27.
STEP 3. Now type the following command: “netsh interface ipv4 set subinterface “interface name” mtu=500 store=persistent”. Replace the “interface name” with
the actual name of the interface being used for the remote connection. As an example, if the Windows computer was using the Ethernet 3 interface, the command would be: “netsh interface ipv4 set subinterface “Ethernet 3” mtu=500 store=persistent”. See Figure 28.
STEP 4. To verify the MTU changed, type “netsh interface ipv4 show subinterfaces”, and look for the subinterface that was changed, and verify the MTU is now 500. See Figure 29.
STEP 5. If desired, to change the MTU back to 1500 afterward, type: “netsh interface ipv4 set subinterface “interface name” mtu=1500 store=persistent”. Replace the “interface name” with the actual name used in the previous steps. To verify the MTU changed back to 1500, type: “netsh interface ipv4 show subinterfaces”. Look for the subinterface that was changed and verify the MTU is now 1500. See Figure 30.
