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.
