Operating Instructions

5 Action in an Emergency

Switching off in an emergency

In an emergency, the supply of electrical energy must be switched off for
the whole system or part of the installation if there is a risk of electric
shock or any other risk caused by electricity.
Besides the controlled switching off of the SL1200A, it is also possible to
switch it off immediately in an emergency.
The following steps result in the immediate switching off or shutdown of
the SL1200A:

Press the emergency stop push button on the SL1200A, or

Emergency stop via external signal of the higher-level safety equip-
ment, if necessary

✓

The power supply of the power path is switched off.

Before switching the system on again after an emergency switch-off:

Determine the cause for the emergency switch-off.

Eliminate the causes.

Observe the note on switching the system back on.

Switching the system back on!
If the main

switch is set to “Trip” due to activation of the emergency stop (un-

dervoltage triggering)

Before switching the system on again, set the main switch to “OFF”.

Only then set the main switch to “ON” to switch back on.
