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 EC700 system incorporates a battery protect circuit that
warns the users and then disconnects the batteries when they fall below set values. If
a warning is active a beep will be emitted by the control panel and information will be
shown
on the screen. To cancel the warning, press the ok button on the pop up window.
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.
The following table shows the fuse allocation for the 13 fuses fitted to the PSU. Please
note that fuses are dependent on PSU versions, so not all fuses may be present.
Note: Fuses (2-10) have a Red LED below them which provides indication that the fuse
has blown. The charger fuse has a green LED which Indicates that the charger is working.
The following table shows details of the fuse(s) located at the Leisure battery. See also

10.9V
Battery selection is
changed from Vehicle
battery to Leisure
battery. If the leisure
battery is below 9V
then a further warning
will occur (see below).
This cut off level is designed to
protect the vehicle battery from over
discharge. The 10.9V level ensures
there is sufficient power in the battery
to run the vehicle electronics and start
the vehicle. This cut off only applies to
power drawn from the battery by the
leisure equipment; it will not protect
the battery if you leave vehicle circuits
switched on, such as the road lights.
Leisure
9V
Power is turned off
This is an emergency cut off level
to protect the battery from severe
damage. You should not rely on this
cut off level during normal operation,
but manage your power consumption
to a discharge level of about 11.5V.
This cut off only applies to power
drawn from the battery by the leisure
equipment that is controlled by the
control panel power switch; it will not
protect the battery from discharge by
permanently connected equipment.

WARNING
When replacing fuses always replace a fuse with the correct value. NEVER
replace with a higher value / rating as this could damage the wiring harness. If
a replacement fuse ‘blows’ do not keep replacing the fuse as you could damage
the wiring harness. Please investigate the fault and contact your dealer.
