upwards. Mounting can be done in the reverse order, also without the use of a lever, by snapping the
bracket on the rail.
The power supply must be connected to a permanent installation by using a protective conductor
and taking into account the
L
,
N
and
PE
markings. It is recommended to equip the installation with a
surge protection system. The power supply voltage should not be disconnected with the main fire
protection switch. It is required to install in the power circuits, outside of the power supply, an installation
switch with a nominal current of at least 3A. The power box and the circuit breaker should be marked
with red color and the power supply number. One switch should protect one power supply. The switch
mounted on the casing of the power supply can be used for testing purposes
– to check the voltage
supply during power failure.
After making the remaining connections (24V voltage outputs and signalization circuits) and after
connecting the external LED signalization harness and possibly the tamper, the batteries should be
connected as the last item.
The power supply has been designed for cooperation with two maintenance-free batteries, which
should be placed in its immediate vicinity. The end of the temperature sensor of the power supply
should be inserted between the two batteries, which afterwards should be maximally pushed together.
Pay special attention to the polarity of the power supply and battery connections. If the connection is
wrong, the battery circuit fuse will be damaged. The following figure shows the polarity of the connected
BAT
battery. Firstly, the batteries should be connected to the power supply packet and then connected
to each other.
The power supply is adapted to connect an external
LED
signalization located, for example, on the
cabinet in which the power supply and batteries have been installed.
It is possible to select between two levels of charging current limitation, battery banks depending on
their capacity. The details are included in the
Electrical parameters
table. Simultaneously with
switching the level of the charging current limitation, the threshold of the permissible resistance of the
battery circuit Ri max is switched over.
By default, a jumper is mounted on the
CL
connector, which sets the higher charging current and the
lower value of the resistance Ri max.
