the power of to prevent severe
discharge of the battery
Note: 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 11.5V or above.
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.

Message on screen and repeated
beeps from the control panel. The
beeping will not stop until the fault is

battery.

4.7 12 Volt DC Fuses
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.
The following table shows the fuse allocation for the 12 fuses fitted to the PSU. Please note that fuses
are dependant on PSU versions and installation, so not all fuses may be present or used.
