Connecting remote signal monitoring
↻ It has been ensured that there is no AC/DC voltage present.
↻ Housing cover open.
1. Loosen the cable fitting to pass the signal cable through [ W_20]
2. Replace the sealing insert in the cable fitting with a multiple sealing insert.
3. Feed the remote signal monitoring signal cable through the cable gland and into
the housing.
NOTE: Refer to the technical details on connecting remote signal monit-
oring!
1. Connect the signal cable to the connection terminal of the DC overvoltage pro-
tection in accordance with the terminal allocation [ S_3,5 / 0.25 Nm]
2. Lay the signal cable correctly and tighten the cable fitting [ W_20 / 1.5 Nm]
ð Remote signal monitoring connected. Proceed with the installation of the
device.
