Integrated power supply unit
Directives for the power supply
The power supply must be connected to the mains via a separate fuse. If the electrical
installation is equipped with a residual current operated circuit-breaker (FI circuit-breaker), the
power supply must be provided with an own residual current operated circuit-breaker. The
fuse and the FI circuit-breaker should be located within the safety area, if possible.
If the power supply is not part of the central unit, it must be mounted nearby (with no
clearance) to ensure that an attack on the connection cable without mechanical damage to
the housings is not possible.
We recommend screwing the central unit and the power supply together. No consumers from
other systems may be connected to the voltage of the power supply.
Only use approved batterys for the power supply. Only use batterys of the same age
and originating from the same production series.
Installation
Disconnect the unit from the power supply when carrying out installation work.
When installing the power supply/charging unit in a central housing, make sure that the insulating foil included
in the delivery is placed between the bottom of the housing and the lower side of the board. Make sure
that the device is firmly screwed to the bottom of the housing.
The ground conductor connected to the supply circuit must be connected close to the connecting terminals of
the supply voltage.
When fastening the power line (NYM 3 x 1,5 mm²), make sure that the min. air gaps (4mm) and creep
distances
(5mm) between the electronic components or the peripheral devices and the power line are maintained.
If the neutral conductor cannot be clearly identified, a second fuse protection must be provided in the supply
circuit enabling a 2-pole separation from the supply circuit.
After installation, protect the connecting terminals against unintentional contact by means of the covers
included in the delivery.
