OPERATION AND MAINTENANCE OF SECOND BATTERY
a)
General
The second battery is charged via the main vehicle battery by the engine alternator. Wired
between the batteries is a 70 amp relay which, when the engine is running, allows a
charging current to pass to the second battery. When the ignition is turned off, the relay
cuts off this isolating the second battery from the main vehicle battery. With the second
battery fitted, all auxiliary equipment fitted by Auto-Sleepers is wired through it thus
ensuring the main battery remains charged.
b)
Maintenance
Terminals should be periodically cleaned and greased. The anchorage of the second
battery should be regularly checked for security as well as when the base vehicle is
serviced.

OPERATION AND MAINTENANCE OF THE ZIG X-3 BATTERY CHARGER
a)
General
b)
c)
d)
The Trophy is fitted with the Zig X-3 battery charging unit, which will charge and
recharge the auxiliary battery by raising its terminal voltage to equal that of the charger
which is 13.8 volts.
Operation
When battery charging is required and 240 volt hook-up is available, the X-3 should be
switched to the 'On' position and the green indicator light will illuminate
as
confirmation
that the charger is working. The unit is fully automatic and no further action is required.
Special Features
The unit is capable of maintaining a stable 13.8 volts output even when connected to lower
input voltages found in Ireland and the continent within the range 198-264 Vac.
Safety Protection
The X-3 is protected by a thermal trip which causes the unit to cut out in the event of a
temperature of 85
°
C being reached or exceeded. When the X-3 cools, the thermister will
allow the unit to operate as before. Further safety features are fitted as follows;
1)
Input fusing - not user serviceable.
2)
Over voltage protection at 15 .4 volts.
3)
Current limiting at 8.0 amps.
4)
Reverse battery protection.

240 VOLT AC MAINS HOOK-UP
The mains circuit is protected by an RCD (Residual Current Device) and two MCB's
(Miniature Circuit Breakers). These units are co-located and are found in the shelved storage
cupboard adjacent to the cooker .
