Some vehicle installations can cater for two
leisure batteries connected in parallel. In these
cases it is recommended that two identical
batteries are used.
The battery feed is fitted with an inline fuse
between the battery and the electrical harness,
and is usually located immediately outside the
battery compartment or within 500mm of the
battery. The maximum rating of this fuse is
20A per battery. If a single battery is fitted to
a motorhome, this fuse may be increased to
40A, however if two batteries are fitted each
battery should be fused at a maximum of 20A.
b. Installation & Removal
Always disconnect the 230v mains supply
and turn the PSU green charger switch to the
off position (button out) before removing or
installing the battery.
When connecting the battery, ensure that the
correct polarity is observed (black is negative
[-] and red is positive [+]) and that the terminals
are securely fastened. Crocodile clips must not
be used.
!
WARNING: Explosive gases may be
present at the battery. Take care to prevent
flames and sparks in the vicinity of the
battery and do not smoke.
c. Operation / Servicing
Under normal circumstances it should not
be necessary to remove the battery other
than for routine inspection of the terminals
and "topping up" of the battery fluid where
applicable. Please see instructions supplied
with the battery.
Note: Do not over discharge the battery.
One of the most common causes of
battery failure is when the battery is
discharged below the recommended level
of approximately 10v. Discharging a battery
below this figure can cause permanent
damage to one or more of the cells within
the battery.

To prevent over discharge, the EC400-450
system incorporates a battery protect circuit
that warns the users and then disconnects the
batteries when they fall below set values.
If the power is turned on and the leisure
battery level falls below 9V a warning beep will
be heard and the leisure battery gauge 10V
LED will flash. To cancel the warning, press the
levels button.
If the power is turned on and the vehicle
battery level falls below 10.9V a warning beep
will be heard and the vehicle battery gauge
10V LED will flash. To cancel the warning,
press the levels button.
These warnings will not be repeated unless the
power switch is turned off and on again. This
is to ensure the warning does not become a
nuisance.
