Installation
Mounting
- The UMD 705 is intended for mounting on the DIN top-hat rail.
Voltage supply
The UMD 705 is available with 2 different voltage supplies:
- The 24 V version requires a voltage of: 20 … 50 VAC 20 … 75 VDC
- The 230 V version requires a voltage of: 85 … 510 VAC 85 … 350 VDC
The connections for this are located at the bottom of the UMD and labelled X1 and X2. It is recommended to protect the voltage supply with a 1 A circuit breaker.
Voltage measurement
The UMD 705 has 3 voltage inputs that are suitable for both direct and current transformer measurements. The phase voltages are measured via the terminals L1, L2, L3 and the joint neutral conductor connection N. It is recommended to protect the voltage paths with a 1 A circuit breaker.
Connecting a current transformer
The universal measurement devices are not designed for direct current measurement. The connections of the required current transformers are located at the bottom of the device and labelled as follows:
- I11 and I12 for the current transformer on phase 1
- I21 and I22 for the current transformer on phase 2
- I31 and I32 for the current transformer on phase 3
The current transformer connection terminals are designed for secondary signals of 1 A or 5 A.
RJ45 interface
The UMD 705E has a standard RJ45 connection for the LAN. The connection is located to the right of the display.
RS485 interface
The UMD 705E is equipped with an RS485 interface that communicates via the Modbus RTU protocol. The connections are located on the top of the device and labelled “A+”, “B-”, and “G”.
Commissioning
Factory communication settings
The UMD 705E is delivered with the IP address 10.0.0.1 by default. The serial interface is pre-set to the device address 1 and a baud rate of 9600 baud.
Connecting to a PC
You can either use an interface converter (e.g. RS485 to USB) or a LAN cable to connect the UMD to a PC.
- Converter: The associated USB driver of the interface converter must be installed on the PC for this.
- LAN: If you want to connect to the device by LAN cable, you need to either adjust your device’s IP address to your network or the IP address of your computer. The UMD 705E is delivered with the IP: 10.0.0.1.
- Open the ENVIS.Daq and select the item “COM” for a USB connection and the item “TCP” for Ethernet.
- Open the drop-down menu and select the COM interface or enter the IP address of the UMD in the field provided for this.
- Clicking “Connect” establishes a connection to the device. You can make all further settings of the device here.
Setting the current transformer
Once you have connected to the device in the software, select the item 
. You can configure the measurement under the tab “Install”: Nominal values, network configuration, current transformer ratios, …
Setting communication parameters
All communication parameters of the UMD can be set under the item “Communication”.
Checking the connection and settings
The connection and settings of the universal measurement device can now be reviewed via the device display or the “Act Data” in the ENVIS. Daq.
- The display of the currents can be used to review plausibility. If you do not know the current, we recommend comparing the current with a current clamp.
- When displaying the individual active powers, consumption is displayed without a prefix and supply with a negative prefix. This permits verification of the correct installation and connection of the current transformers. Only the total power can be checked on the UMD 705 display!
- The pointer diagram can be used to check the rotating field and assignment of the current and voltage paths. Observe the phase shift of current and voltage for this.
