12 Decommissioning/disposal
12.1 Decommissioning
• All work must be carried out with the greatest
care.
• Proper protective clothing is to be worn.
• When working in enclosed spaces, a second per-
son must be present for safety reasons.
12.1.1 Deactivating automatic mode on the unit
1. Select menu item 3.01
2. Select “OFF”
12.1.2 Temporary decommissioning
For temporary deactivation, the control is
switched off and the switchgear is switched off via
the main switch.
The switchgear and the unit are now ready for
operation at any time. The defined settings are
stored retentively in the switchgear and are not
discarded.
Make sure that the ambient conditions are
observed accordingly:
• Ambient/operating temperature: 0 ... +40 °C
• Humidity: max. 90 %, non-condensing.
CAUTION! Beware of moisture!
The ingress of moisture will result in damage
to the switchgear. During standstill periods, pay
attention to the permissible humidity and
ensure the switchgear is stored so that it is
overflow-proof.
Switch off the switchgear using the main switch
(“OFF” position).
12.1.3 Final shutdown
RISK OF FATAL INJURY due to dangerous elec-
trical voltage!
Incorrect procedures can cause fatal electric
shocks.
This work may only be carried out by a qualified
electrician in accordance with locally applicable
regulations!
1. Switch off the switchgear using the main
switch (“OFF” position).
2. Switch off the entire unit so that it is voltage-
free and secure it against accidental activa-
tion.
3. If the terminals for SBM, SSM, EBM and ESM are
occupied, the external voltage source present
there must also be switched to a voltage-free
state.
4. Disconnect all power supply cables and pull
these out of the threaded cable connections.
5. Connect the ends of the power supply cables
so that no moisture can enter into the cable.
6. Remove the switchgear by undoing the screws
on the fire-extinguishing system/building
structure.
