2. Set-up
▪
During set-up apply directions of this manual
▪
Mount devices in a place without direct insolation
▪
Mounting and connecting could be carried out only without batteries
▪
Observe proper polarity when connecting batteries
▪
The device must be powered from the utility power grid with a protective earth
terminal
▪
Check the quality of all done connections before switching the device on
2.1. Mounting
The power supply should be mounted in a carefully selected place, to minimize the risk of mechanical
damages and not to exceed allowable ambient temperature and humidity. Power supplies of fire
protection equipment should be mounted nearby this equipment to minimize voltage drop. If possible, the
power supplies should be mounted in rooms separated as fire resistant areas (e.g. switchboard rooms,
technical rooms, cable chutes)
The box should be mounted on the wall, using four holes in the rear side of the box. Before mounting,
one has to open the box, unscrew three nuts fixing the chassis of the power supply to the rear face of the
box and remove the power supply.
The empty box has to be fixed to the wall by 4 steel sleeves and screws. Wall plugs made of PVC can
not be applied. If there is a need to lead wires between the box and wall one has to fix enclosed brackets
to the box before mounting on the wall. Having the box fixed to the wall one has to mount the power
supply back. .
Location of the mounting holes is show in the section 1.2. Technical data.
2.2. Connections
One has to remember to connect the device to the permanent wiring using protective earth wire. It is
recommended to outfit the installation with a surge protection system. The input voltage should not be cut
off by the master fire protection switch.
The power supplies have no own mains power circuit breakers, so a dedicated, overcurrent and short
circuit resistant breaker of at least 3 A current is required in the powering installation (outside the power
supply). The switchboard panel and breaker of the fire protection power supply should be clearly marked
(by red color and number of the power supply or by a proper description). One breaker should protect
one power supply. Using this breaker for other loads is impermissible.
The installation cables can enter the box from the top through three cable glands DW20-RM and one
DW16-RM (dedicated for remote indication cables). All connections should be carried out according to
the diagram inside the box (on the door). Holes of unused transits should be plugged by the plugs
enclosed to the device.
