2 LOCATION
The charger can be mounted in a vertical or horizontal position in either plain. It should be located in a
ventilated area away from any moisture. The ventilation slots on the charger must be kept clear at all
times. Do not cover the unit.
3 CONNECTION
230v
The charger requires a 230v supply protected with a fuse rated at no more than 6A.
The charger is supplied with a 300mm mains input leads with a 3pin JST plug.
The pin-out connections are as follows: ‘D’ shaped terminal = Live, Centre terminal = Earth, Remaining
terminal = Neutral. Note that this pin-out arrangement is different to similar wiring connectors in some
caravans.
12v
The 12v output must be protected with a fuse rated at no more than 20A, which should be located as
near as practicable to the charger [+] output terminal.
The charger is supplied with a 300mm 12v output leads with two ¼” insulated blade connectors. The
pin-out connections are as follows: Red = [+] Positive, Black = [-] Negative.
4 OPERATION
The charger has an inbuilt battery ‘exercise’ feature that ensures the battery is actually ‘used’ and not
just continually charged.
This circuit works by monitoring the battery voltage at initial switch on (when the mains supply is
applied to the charger). If the battery voltage is greater than 12.8 volts the charger will not switch on
until the battery voltage drops to around ~12 volts. This allows the battery to deliver power to the
vehicle for a limited period of time. The battery then receives a recharge to restore it to the fully
charged state.
However, if the battery voltage is less than 12.8 volts at switch on, the charger will switch on
immediately, powering the vehicle and charging the battery.
The ‘exercise’ circuit only operate on a one off cycle, i.e. each time the mains supply is applied.
5 SERVICING
The charger has no user serviceable parts.
6 SAFETY
Switch OFF mains supply before connecting / disconnecting the battery.
Observe battery polarity, check before connecting if unsure.
Ensure there is free movement of air around the charger.
Never cover the ventilation slots or obstruct the cooling fan.
