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.
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 EC600 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 select 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.

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.
