Installation GRS105/GRS106
Release 01 11/2021
49
For every supply voltage to be connected, perform the following work
steps:
 Remove the terminal block from the device.
 Connect the wires according to the pin assignment on the device with
the clamps.
 Fasten the wires in the terminal block by tightening the terminal
screws.
You find the prescribed tightening torque in chapter:
“General technical data” on page 61
6.6.2 Supply voltage characteristic value L
Exclusively supply your device with SELV/ES1 voltage.
You will find information on the characteristic values here:
“Device name and product code” on page 21
You have the option of supplying the supply voltage redundantly, with load
distribution.
Both supply voltage inputs are electrically isolated.
