USES
4 outputs are available on the distribution unit, protected by alarm-indicating fuses. The available fuse ratings
are 2A, 5A and 10A and these can be ordered from Alpha Technologies.
When a fuse is blown, a coloured dot indicates the circuit is open. The fuses are numbered from 1 to 4, fuse 1
corresponding to the most left DC output and so on from left to right.

REAKER
If the battery is correctly connected, the user can set (close) the LVD by pushing the button of the battery circuit
breaker. When the LVD is active (closed), the green “LVD OK” LED on the front of the distribution unit and the
green “LVD OK” LED on the front of the controller illuminate. By pulling the button of the battery circuit breaker,
the LVD will open and the battery is disconnected from the system. Both green LEDs will then extinguish.
The status of the battery circuit breaker is monitored by the controller and can be used as an alarm source.
CAUTION
CAUTION! Before plugging and unplugging the battery connector, the user should pull the
battery circuit breaker and check whether the LVD is non-active (open) to avoid damaging the
battery connector contacts.

The battery connector is a 2-pole Phoenix contact PC 4/2-G-7,62 (18 04 79 7)
The battery mating connector reference is Phoenix contact PC 4/ 2-ST-7,62 (18 04 90 4)
The battery capacity is limited by the interrupting capacity of the 20A battery circuit breaker and should not
exceed 62Ah.

CAUTION! Before plugging and unplugging the battery connector, the user should pull the
battery circuit breaker and check whether the LVD is non-active (open) to avoid damaging the
battery connector contacts
