Safety instructions
Installation and mounting of electrical devices may only be
carried out by qualified electricians.
Failure to observe the instructions can result in damage to the
device, fire or other dangers.
Isolate before working on the device or load. Take account of all
circuit breakers supplying dangerous voltage to the device or
load.
i
Provide circuit breaker!
Connect a circuit breaker type D, max. 16 A upstream from the
power supply unit.
Function
Power supply unit with input voltage of 115 V -15 % to 230 V
+15 % AC. Output voltage 24 V DC with uninterruptible power sup-
ply (UPS). If the mains input voltage drops, connected load is sup-
plied interruption-free via the integrated batteries. When the mains
input voltage recovers the batteries are separated from the load and
recharged via the internal charging unit.
The device is designed for 24-hour operation at rated output.
Self-diagnosis for monitoring of the batteries e. g. for protection of
complete draining etc.
Operating states (mains failure, battery warning and charging device)
of the power rectifier can be signalled via the zero-voltage relay con-
tacts (see figure 2).
i
Note: read the system operating instructions.
Become familiar with all the possibilities of the device and the
complete call system. Please read the system operating instruc-
tions available in various languages on the CD-ROM enclosed
with the ward control centre.
