1. Introduction
This section of the handbook will guide you
through the operation of the electrical system.
Further technical details are contained in
section 3 or in the supporting dealer technical
manual available from www.sargentltd.co.uk
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.
