Installation GRS105/GRS106
Release 01 11/2021
The supply voltage is electrically isolated from the casing. The power supply
units are protected against polarity reversal.
With a non-redundant supply of the supply voltage, the device reports the
loss of a supply voltage. You can prevent this message by applying the
supply voltage via both inputs, or by changing the configuration in the device
management.
5.4.1
Supply voltage characteristic value G
You have the option of supplying the supply voltage redundantly, with load
distribution.
The supply voltage is electrically isolated from the casing.
Note:
The supply voltage is connected to the device casing through
protective elements exclusively.
