5. Commissioning
5.1 Check proper connection
Observe the relevant standards and regulations for installation and connection as well
as the operating manual of the respective device.
5.2 Before switching on
Consider the following questions before switching on:
1. Does the connected supply voltage correspond to the information on the
nameplate?
2. Has the nominal insulation voltage of the measuring current transformers
been exceeded?
3. Does the measuring current transformer's maximum current correspond to
the nameplate information of the connected device?
5.3 Switching on
To switch the device on, follow the steps below:
1. Connect the supply voltage.
2. Set the bus address/IP address.
3. Set the CT transformer ratio (for each channel).
4. Change the measuring current transformer's counting direction, if required.
5. Set the nominal voltage (line-to-line voltage U
LL
).
6. Select wye connection or delta connection.
5.4 System
The universal measuring device PEM735 can be programmed and queried via Modbus
RTU/Modbus TCP. For details refer to the Annex "PEM735-Modbus".
In addition, it is possible to integrate the device into Bender's own bus protocol BMS
bus (
B ender M essgeräte S chnittstelle) via additional communication modules. In this
way, communication with (already existing) Bender devices for device parameterisation
and visualisation of measured values and alarms can be achieved.
