required.(Settings > Basic > I… Polarity).
6. Set voltage potential ratio (Settings > Basic > PT Primary/Secondary or U4 Pri-
mary/Secondary).
7. Set nominal voltage U
LL
(Settings > Basic > Nominal VLL).
8. Set nominal frequency (Settings > Basic > Nominal Freq).
9. Select wye connection or delta connection (Settings > Basic > Wiring Mode).
5.6 System
The PEM735 can be programmed and queried via Modbus RTU/Modbus TCP. For more
details, refer to 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.
Help and examples of system integration can be found on the Bender homepage
www.bender.de or you can contact our Bender Service for personal advice (see
"chapter 1.2 Technical support: Service and support“).
Please observe the device variant!
The nominal frequency can be changed to the value deviating from the
device type. However, in this case, the accuracy class 0.2 S is no longer ful-
filled.
