1. Introduction
This section of the handbook will guide you
through the operation of the electrical system.
Further technical details are contained in

For the safe operation of all electrical
equipment within your Leisure Vehicle it is
important that you read and fully understand
these instructions. If you are unsure of any
point please contact your dealer / distributor
for advice before use.
The system has a number of key components
that you will need to be familiar with before
attempting to use the system, these are:
• The EC series Power Supply Unit (PSU)
a combined mains consumer unit and 12V
controller located in the front locker or bed
box area.
On locker mounted caravan versions this unit
also contains the provision for the Radio/
CD head unit. The EC400 / EC450 series
of power supply units include the EC400
range (horizontal units) and the EC450 range
(vertical units), further details are contained
later in this document.
• The EC series Control Panel (CP)
- a remotely located user control panel used
to turn circuits on and off and to display
battery and water tank information. This
panel uses simple straightforward controls
and reliable data communication to the PSU.
• Road Light Fuse Box
This small unit, which is unique to caravans,
is located in the front bed box. The unit
houses fuses for the road lighting circuits
and supplies from the tow vehicle, and also
has connectors for the optional alarm system
and Automatic Trailer Control (ATC) unit.
