4 CEC BATTERY CHARGER AND POWER SUPPLY UNIT
4.1 INTRODUCTION
4.1.1 The CEC battery charger is located in the forward facing section of the 'L' shaped
settee on the offside; access is through the base of the settee; the battery
charger is mounted on the inner face of the settee wall adjacent to the gang way.
The Inter-Power from Plug-ln-Systems Ltd is an extremely light weight and
efficient unit, combining power and safety to provide the ultimate in battery
chargers. It is especially designed for caravan and motorhome installations,
simple to install and requiring minimal attention in use. A rocker isolation switch
is fitted to the top face of the battery charger. We recommend this is left "ON" at
all times: it only needs to be switched off when the limit may require isolating, for
example, for servicing or repair.
4.1.2 The unit incorporates important safety features:
OVERCURRENT PROTECTION
SHORT CIRCUIT PROTECTION
REVERSE POLARITY PROTECTION (BATTERY)
The Inter-Power is designed to work with a battery in circuit and for optimum
performance a good quality Leisure battery is recommended.
4.2 Unit Description
4.2.1 With the unit connected to a protected 240 volt electrics, its operation is fully
automatic once switched on. The unit is capable of providing up to 12 amps,
should this load be exceeded then the Inter-Power will enter current limit mode to
prevent damage to itself and associated 12 volt installations.
The Inter-Power will, if necessary, operate on a low mains input (making ideal for
low continental voltages) and still provide a stable (regulated) dc output voltage.
As a precautionary measure a de fuse is fitted in the output circuit of the Inter-
Power, in normal use this fuse should not require attention.
4.2.2 W arning: If using the Inter-Power in conjunction with a generator, first check the
output voltage is no higher than 240 volts as failure to do so could result in
damage to the unit.
4.3 Operation
a) Connect mains 240 volts ac to the caravan/motorhome via Mains Inlet
Socket.
b) Switch the RCD (on the mains protection unit) to the ON position
(upwards).
c) Switch the relevant MCB (6 amp) to the ON position (upwards).
d) Switch ON the Inter-Power, at this point power will be available from the
Inter-Power via the dc output connectors. If this is not the case, check all
connections and fuses.
