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. Switch off all appliances and
lamps before connecting or disconnecting
the leisure battery.
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.
12V Operation of Electrical Items
Most appliances within your product are
designed to function when supplied with a
12V feed, either from a leisure battery or the
on-board charger.
However, customers should note that some
items may have limited functionality when the
battery is in a lower voltage state (i.e. circa
10V). The Swift Group makes every effort
when specifying components to operate at low
voltages, but is not responsible if a component
fails to work at lower voltages.
76
Components that are typically affected by low
battery voltage include, but are not limited to,
the pump, the radio and some lights which
require higher voltages for start-up.
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.
