Overview
4.1.
The Traction range of Battery Support Units
convert nominally 110-120V ac 60Hz 8A to
13.8V dc 50A. This enables you to operate a 12V
nominal DC load up to the units rated output
current as demanded by the attached load.
4.2.
Each Battery Support Unit has been designed
with high quality components to help ensure
years of continuous use. The Support Units are
protected by multiple protection features in
order to ease of use:
Reverse polarity protection
–
the centre LED
should show green for good or red for incorrect
connection.
Over-current protection
Over temperature protection
Short circuit protection
Backward voltage protection
–
if the voltage at
the terminals is higher than the Support Unit
supply a relay will be heard cutting in and then
cutting out to check voltage level.

Installation
There are no components within the Battery
Support Units that, in their normal operation,
produce arcs or sparks. All electronic devices
have some potential for generating sparks in the
event of failure.
Therefore, never install this
device in the same compartment with
flammable items such as gasoline or batteries.
5.1.
Installation Location
BSU2-50 and BSU2-125 have been designed to
be trolley mounted (Part number JLR-Trolley-
US). The trolley comes complete with mounting
bracket. Battery support units should not be
rested in engine bay due to risk of damage
either to vehicle or equipment. Showroom
support unit SSU2-50 has been designed to sit
under the supported vehicle. Ensure that unit is
placed on fitted rubber runners and that there
is at least 5cm of clear space on all sides
excluding base. Ensure the mains socket is near
the equipment and easily accessible at all times.
The unit can be wall mounted in a vertical
orientation only with the connections at the
bottom.
Neither BSU2 or SSU2 should not be positioned
so that the label is either upside down or
invisible.
5.2.
Connecting to a vehicle
Please follow dealer standards guidelines for
connection methods. Traction units are supplied
with vehicle specific adapters that should be
used at all times. Failure to use the adapters in
the positions prescribed could result in
excessive heat being generated in the lead set
leading to premature failure of leads and low
voltage output.
