Plugs for output connection are supplied with the power supply unit. Maximum cross-section of the
connected wires is 6 mm2 in case of outputs provided for amplifiers and 2.5 mm2 for the 24V power
supply output providing power supply for the VAS controllers and other VAS modules.
The CHARGER 6 power supply is equipped with two power supply outputs for VAS controllers, while
the CHARGER 12 power supply unit is equipped with four such outputs. If the VAS system requires a
higher number of controllers and cooperating devices to be used, corresponding splitting should be
implemented outside the power supply unit.
connecting battery bank
Power supply units are designed to cooperate with VRLA-AGM battery banks.
Note: Because the power supply unit is not equipped with a battery bank circuit breaker,
appropriate circuit breakers, separate for each of the battery banks, should be installed near each
positive terminal of each battery.
Connection of a battery set should be made using connector wires with a maximum cross-section of
16 mm2 for terminals located in the back panel of the power supply unit, marked as Bat taking a
proper care to provide them with a proper polarity. A reverse connection of a battery bank may result
in severe fault to the power supply unit itself, as well as in connected, external devices.
Positive terminal poles, marked with numbers, enable distinguishing of battery banks as each of them
is supervised separately. Negative poles are short-circuited together.
The
M
outputs of the voltage compensation circuit should be connected with the center of the
appropriate battery string by means of the cables of the cross section of 0.75mm2. The connection
must be protected near the battery with its own fuse of 0.5 ... 2AF.
Note:
If only single battery path is used, so connect to Bat1
If two battery pathes were used, so connect to Bat1 and Bat2
If three battery pathes were used, so connect to Bat 1, Bat2 and Bat3
Minimum Akku capacity is 45Ah recommended is 65Ah or higher!
Remind maximum current for each battery-connector is 90A
Connecting external fault indication system
The power supply is equipped with two inputs for connecting external fault indication systems, the
sockets of which are located in the back panel. Corresponding plugs are supplied with the power
supply unit. One of the plugs has a factory pre-installed jumper and it has to be placed in the alarm
socket
EXT. FAULT 1
, even if this input is not used, since it is activated when its contacts become
disconnected.
The second input
EXT. FAULT 2
is activated by short-circuiting its terminals.
External fault indication systems should be connected using fire resistant type cables (the cross-
section of 0.8 mm2).
Output of remote indication
Outputs of remote relay indication are implemented as 3-pin sockets. The power supply unit is
supplied with 2-pin plugs. You can use the normally connected (NC) or normally open (NO) contacts of
the internal indication relays by placing them in the appropriate socket. Remote indication circuits
should be connected by using fire resistant type cables (of the cross-section of 0.8 mm
2
)
Temperature sensor connection
The external temperature sensor supplied with the power supply unit should be connected to the
appropriate socket (
Temp sensor
). The sensor should be placed in a direct proximity of the battery bank,
if possible, between the walls of two adjacent batteries.
