7.21.11 Connecting the secondary equipment
Wires for secondary equipment can be laid to the side, to the rear or downwards. For panel
blocks, wire routing across panels is possible through the wiring duct located on the operating
mechanism box (option) or through the front operating mechanism box. For extendable
switchgear, wire routing through the wiring ducts is recommended.

NOTICE
Blocked ready-for-service indicator
Wires for secondary equipment can block the transmission linkage of the ready-for-service
indicator. This can damage the switchgear due to an incorrectly indicated service readiness.
⇨ Lay the wires at a large distance to the transmission linkage.
