NOTICE
Maloperation
The locking bracket at the circuit-breaker truck is exclusively designed for
interlocking the circuit-breaker truck with the switchgear frame.
As long as the circuit-breaker truck is not completely moved into the
panel, the locking indication at the locking bracket must show
UNLOCKED!
Operate the locking bracket only if the circuit-breaker truck has been
completely moved into the panel.
Do not push the locking bracket downwards towards LOCK if
• the circuit-breaker truck is outside the panel.
• the circuit-breaker truck is moved only partially into the panel.
