Control cables
Pay attention to suf
fi
cient distance from powerlines and motor wires to prevent interferences. The
control cable may not be longer than 30 m. Screened control cables must be used when the cable
length is longer than 20 m. When using a shielded cable connect the shielding to one side only, i.e.
only to the control unit with the protective ground (keep cable short and with as little inductance as
possible!).
5.12
Potential at control voltage connections
The control voltage connections (< 50 V) relate to the joint GND potential (Exception: Relay contacts
are potential free). There is a potential separation between the control voltage connections and the
protective earth. It must be ensured that the maximum external voltage at the control voltage
connections cannot exceed 50 V (between
“
GND
”
terminals and
“
PE
”
protective earth). If necessary, a
connection to the protective earth potential can be established, install bridge between
“
GND
”
terminal
and the
“
PE
”
connection (terminal for screening).

The internal accumulator for line substitute supply of the alarm
device
A high quality lead accumulator is installed for the energy supply to the alarm device. This automati-
cally takes over operation of the device without interruption in case of faults in the main supply. This
accumulator enables uninterrupted operation of the alarm device for at least 2 hours.
When mains power is available, the accumulator is charged constantly to keep maximum capacity
available at all times. At the same time the state of the accumulator is monitored and signalled
accordingly in the event of a fault.
In the as-delivered state of the ALARMcon the accumulator is fully charged and has a self-discharge
of only 3 % per month as speci
fi
ed by the manufacturer. To prevent discharging due to own
consumption of the ALARMcon,
the accumulator is not switched on in the as-delivered state!
6.1
Switch on the accumulator before start-up
Danger due to electric current
•
Do not remove the housing cover under voltage, observe the safety instructions!
•
Caution: Never short-circuit the connection terminals of the accumulator!
•
Only use accumulators approved by ZIEHL-ABEGG for this device!
Information
•
The accumulator must be switched on before starting the device. The switch is accessible after
removing the connection cover.
•
Since we have no in
fl
uence over the storage duration before start-up, a safe mains substitute
supply can only be guaranteed after suf
fi
cient supply duration with mains voltage despite the low
self-discharge.
•
Caution: Make sure the new accumulator is connected with the correct polarity!
