CONNECTION OF SERVICES
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 could be up to 40A, however, if two batteries are fitted, each
battery should be fused at a maximum of 20A.

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 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.
Battery Voltage Cut off Action after cut off
Notes
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.
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.
