When the Extinguishing Control Computer is delivered from the factory, the plug connections for the PE
connection are correctly attached. If the boards are installed and removed, ensure that this factory PE
connection is always restored at all points.
The 230 V AC mains supply must be installed in accordance with local regulations by a qualified technician. The
AC connection terminals are located on the Basic module.

Mains connection requirements
•
The Extinguishing Control Computer must be supplied from the 230 V mains through a separate isolator or
an appropriately labelled safety switch. The required mains voltage (230 V AC) is given on the panels
nameplate.
•
In buildings fitted with earth fault devices (FI protection), a separate device must be installed for the fire
alarm system.
•
The fuse for the power supply of the Extinguishing Control Computer must be clearly labelled with the red
marking 'FACP'.
•
The protective earth conductor of the mains cable must be connected to the corresponding screw terminal
at the fire alarm panel (ref. to section Protective and Functional earth).
•
Use an appropriate mains cable, e.g. NYM 3 x 1.5 mm
The installation must comply with local regulations on electrical safety.
AC mains voltage
The required mains voltage (230 V AC) is given on the panels nameplate.
Cable insulation
Make sure to lead all cables complete with their outer sheaths intact into the cabinet. Only remove the
insulation from those sections which are inside the cabinet.
Power supply
The fuses of the panel or external power supply units cannot prevent an unexpected fault in electrical
modules; rather, these fuses are intended to protect users and their surroundings from damage.
Therefore, never repair or bridge the fuse that is installed (e.g. T1A H/250V) or replace it with anything
other than the stated type!
