N.B. The information provided in this
Guide relating to fitted equipment is
only intended as a quick reference.
Comprehensive details of maintenance
and fault finding charts where
appropriate can be found by referring
to the accompanying manufacturers
literature. If any doubts still exist about
the operation of the equipment qualified
personnel or your caravan retailer
should be consulted.
Your caravan will be fitted with either a ZIG,
Power Centre II or BCA Leisure charging and
power distribution unit.
ZIG X7/X8 CHARGING UNIT & POWER
SUPPLY
The Zig is a fully automatic battery charger,
connected to a six-cell lead acid battery (not
supplied) with a nominal voltage of 13.8 volts,
the unit will charge and re-charge the battery by
raising the terminal voltage to equal that of the
output of the battery charger. As the battery
voltage increases the input current from the
battery charger automatically reduces until it
ceases to flow. This provides fast and efficient
battery charging and eliminates the possibility
of overcharging , unless the battery is at fault.
The charger is designed to charge 12V lead
acid type batteries, the capacity of the battery
must not be less than 60 ampere hour. (The
bigger the battery the better.) Should the battery
contain a faulty cell, the terminal voltage will not
rise sufficiently to switch the charger off and the
battery will eventually boil dry. The most
common cause for cell failure is discharging the
battery below the recommended level of
approximately 10V.
Please note that any drop in voltage
coming in will reduce the output.
It is recommended that you fit a sealed-for-
life battery.
WARNING:
Under no circumstances should a fuse
of different size or rating be fitted.
Should a fuse blow for any reason, the
fault must be diagnosed before
replacement.
