7. Mounting and installation
During installation, all the manuals for system modules and components must be taken into account.
7.1 Safety instructions for installation
DANGER Electric shock hazard! Fatal injuries or death from contact with cables and terminals.
· Only connect or disconnect cables while they are de-energized. · Take measures to prevent the power cable from being reactivated.
NOTICE Damage due to improperly connected wires and cables! Incorrectly connected cables can lead to damage or destruction of the measuring inputs and the device.
· Connect cables only to the sockets provided for this purpose. · Observe the polarity while connecting cables.
NOTICE Damage due to overvoltage! Overvoltages or surge voltages may damage or destroy the device.
· Protect the power supply against overvoltages.
Voltages of more than 24 V DC and currents of more than 20 mA on the analog and digital inputs can destroy the respective measuring inputs.

7.2 Installation
7.2.1 Installing the device on a top-hat rail
Steps 1. 2.
3.
Hang the blue’Log on the top-hat rail using the clamp provided (rear panel).
Push the top-hat rail latch on the front side of the device from bottom (latch
open) to top (latch closed). This will attach the blue’Log to the top-hat rail. The icons (open/closed lock) above and below the top-hat rail latch indicate whether the device is attached.
Check that the blue’Log is securely attached to the top-hat rail.
Fig. 4: Secure mounting on a top-hat rail
7.2.2 Dismounting the device To remove the blue’Log from the top-hat rail, push the top-hat rail latch from top to bottom. The device can now be lifted off from the top-hat rail.
NOTICE For installation within a control cabinet, ensure at least 3 cm of free space above and below the device for air circulation.

7.2.3 Mounting MX modules on the device
The blue’Log can be expanded to provide additional interfaces using various add-on modules (MX modules).
Fig. 5: MX module (example: RS485/422)
NOTICE
Risk of damage when installing add-on modules Installing MX modules while the blue’Log is operating can damage or destroy the blue’Log and the MX modules.
· Before installing MX modules to provide additional interfaces, disconnect the blue’Log from the power supply.
Steps 1. 2.
If necessary, remove the blue’Log from the top-hat rail.
In order to add an MX module to the blue’Log, remove the cover on the right-
hand side. For this, unlock the four fasteners and pull off the cover on the
right-hand side.

Set the side cover aside, as you will need to reattach it to the right side of the MX module later. This is required in order to fasten the blue’Log and MX modules to the top-hat rail.
3. You can now see the expansion socket on the right-hand side of blue’Log
housing.

7.2.5 Connection sequence for MX modules
When connecting MX modules to the basic device, observe the prescribed connection sequence in order to ensure correct functionality of the modules.
The number of arrows and lines on the bottom front panels of the blue’Log and MX modules indicates the connection sequence. Modules with a greater number of arrows/lines may not be installed before a module with fewer lines (e.g. two arrows/lines). For example, a module with three arrows/lines must not be connected before a module with two arrows/lines.

7.4.1 Power supply The power supply of the data logger must comply with the requirements below.
· Power supply:
24 V DC; 3.33 A max. 80 W
CAUTION
Complying with limit values for power supply
Ensure that the following limit values are complied with.
· IEC 61010-1
(or EN/CSA/UL— 61010-1)
Power supply of limited-energy circuits with Safety Extra Low Voltage
(SELV)
· EN 60950-1 Power supply with limited power sources
NOTICE
Installing the power supply The power supply including any protective devices may only be installed by a qualified electrician.
7.4.2 Voltage output · Voltage: 24 V DC
blue’Log XM / XC
22 |27
The blue’Log can supply sensors with a maximum current consumption of 500 mA. For sensors with a current consumption totaling more than 500 mA, please use an external power supply.
8. Commissioning and configuration
8.1 Requirements
In order to start up the blue’Log, the device must be securely mounted, and all cables must be properly connected.
NOTICE A damaged device must not be put into operation!
8.2 Commissioning
1. Switch on the power supply 2. Wait until the blue’Log has finished booting. 3. The status LED on the device will light up.
NOTICE During connection of the power supply it is imperative to ensure correct polarity (+ / -).
8.3 Establishing and checking the connection
8.3.1 Ethernet connection The blue’Log can be integrated into a local network using a patch cable. Once the Ethernet connection is established, you can directly access the device and internet via the network. A 1 m long Ethernet patch cable is included with delivery.
8.3.2 Connecting bus devices The blue’Log is equipped with two RS485 interfaces (RS485-1 und RS485-2) for connecting bus devices. These can query information from typical bus devices such as inverters, energy meters, string monitoring systems and power analyzers. Sensors and meters can be queried together if they communicate via Modbus.
blue’Log XM / XC
23 |27
Please note the following regarding bus cabling:
· Each RS485 interface supports only a single protocol (for example, Modbus).
· Devices from different manufacturers or categories with a Modbus RTU protocol can be mixed at one bus line. However, we do not recommend this because it reduces the performance and quality of Monitoring and Power Control functions.
· If devices from different manufacturers or categories with a Modbus RTU protocol are connected to one RS485 interface, then the baud rate and protocol frame of the RS485 settings must be the same (see Compatibility list).
· The blue’Log functions exclusively as a Master on the bus. · Observe the maximum permitted number of bus devices (see Compatibility
list). · The order of the bus devices on the bus is unimportant. · A repeater must be used for every 32nd bus device and for long cable runs.
· The bus should be cabled with a twisted and shielded pair of wires. · The shield of the bus cable must be grounded at one end of the connection
only. The blue’Log does not have its own grounding. · When wiring the bus wires, the AC and DC cables must be routed
separately. · Do not switch the bus signal wires. · Manufacturers interpret the underlying standard of the RS485 interface
differently. This means that the A and B wire labels may be different depending on the manufacturer. The + and indicators, on the other hand, are unambiguous.
· To prevent reflections, the bus must always be terminated with a parallel terminator.
· For more information, see the device connection plans.
8.3.3 Connections to analog and digital inputs The blue’Log has several digital interfaces or analog/digital interfaces for recording and evaluating analog and digital signals.
· Devices with analog or digital outputs can be connected via the digital and analog inputs of the blue’Log.
· Typical devices for these interfaces are ripple control receivers, remote control systems and sensors.

8.4 Configuring the blue’Log
The necessary steps for the initial setup of the blue’Log via the display screen and web interface can be found in the blue’Log XM / XC Quick Start Guide.
8.5 Factory reset
The blue’Log can be reset to factory settings at any time. In line with cyber security standards, the factory reset and data deletion process ensures that all data is fully erased and the product is reset to its default settings.
The factory reset returns the device to its original, secure configuration. It erases the following:
· Logged data · Events · User data · Roles · User-configured settings
Resetting to factory settings will erase all the data stored on the blue’Log! The data can not be recovered!
Prerequisites · You have performed a backup of your configuration
Steps 1.
2. 3. 4.
On the blue’Log device, hold down ESC for at least 5 seconds until the following information appears on the display: Press OK for factory reset. Release the ESC key and immediately press OK to confirm. Wait until the blue’Log has restarted. The device has been reset to secure factory settings.
