UPC Universal Power Charger User Manual, Part No 96550-96580, 12th October 2007
Connections
Mains Connection
This equipment is designed for connection to public low-voltage single phase AC mains supplies. It is
built to insulation class 1, and so must be earthed. The input voltage range for each model is given in
the product specification at the end of this manual.
The wires in the mains input lead are coloured in accordance with the following code:
Blue:
Neutral
Brown: Live
Green/Yellow: Earth
The unit is equipped with a mains input fuse, located inside the unit. Rupture of this fuse is indicative
of a unit fault; it is not a user serviceable item.
The unit’s input current permits mains connection of the UPC800 & UPC1600 models via an
appropriate non-reversible mains plug if desired. If a standard UK domestic plug is used, it should be
fitted with a 10 amp fuse. The input current of the UPC3200 exceeds the capacity of the UK domestic
plug, so a blue BS4343 industrial plug or a hard-wired connection is required.
Local regulations, or regulations applicable to the intended application of this product, may override
or impose additional requirements, which must be taken into account. Attention is drawn to the
requirement for residual current circuit breakers in some vehicular applications.
Output Connections
WARNING: EXPLOSIVE GASSES MAY BE GENERATED BY A BATTERY ON
CHARGE. TO PREVENT IGNITION, ALLOW TIME FOR GASSES TO DISPERSE
BEFORE ATTEMPTING TO CONNECT OR DISCONNECT THIS UNIT TO OR
FROM THE BATTERY.
The Power Charger is normally supplied with two flying leads for the DC power output. The heavy
gauge red lead is the connection to system positive, and the black lead to negative. Positive,
negative or isolated chassis circuits may be connected. Be sure to disconnect the input supply before
making or removing the connections to the battery.
Ideally, in battery charging applications, both the positive and negative leads should be routed
directly to the battery terminals. This ensures that the Power Charger system responds only to the
battery conditions, without being disturbed by other connected equipment. The unit is suitable for
permanent connection to the battery.
If a temporary connection is made to an automobile battery whilst in situ, proceed as follows:
•
Ensure that the AC input supply is disconnected.
•
Then connect the appropriate output conductor to the battery terminal which does not
connect to the vehicle chassis (normally positive on negative earth vehicles), then
connect the other output conductor to the battery terminal which connects to the vehicle
chassis.
•
Connect the AC input supply.
•
To stop charging, disconnect the AC input supply, wait for gasses to disperse, then
remove the battery connections in reverse order.
The leads may be shortened if required.
If longer leads are required, the leads supplied can be replaced or lengthened, using suitable cable,
up to a maximum extended length of around 5 metres. Systems with extended cables will benefit
