UPC Universal Power Charger User Manual, Part No 13142-01, 12th October 2007
Page 3
24 VOLT MODELS:
Flooded and retained electrolyte lead acid batteries of 24 volt rating, being made up from 12 identical
cells connected in a series configuration.
36 VOLT, 48VOLT, 72VOLT & 96VOLT MODELS
Flooded and retained electrolyte lead acid batteries of the same voltage rating, being made up from
identical 2 volt cells connected in a series configuration, or banks of 6 identical cells (ie identical 12
volt packs) connected in a series configuration.
No attempt should be made to charge non-rechargeable batteries with this unit, as a hazard could
result.
IMPORTANT SAFETY INFORMATION
1. Please read and observe the installation instructions, which contain further safety information.
2. 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.
3. Statutory Notice: The wires in the mains input lead are coloured in accordance with the following
code:
Blue: Neutral
Brown: Live
Green/Yellow: Earth
If the colours of the wires in the mains lead of this equipment do not correspond with the markings
in your plug, proceed as follows:
The Blue wire must be connected to the terminal marked N or coloured Black.
The Brown wire must be connected to the terminal marked L or coloured Red.
The Green/Yellow wire must be connected to the terminal marked E or coloured Green.
THIS EQUIPMENT MUST BE EARTHED
4. Low Voltage Circuits
This equipment must be installed in such a way that high currents present in any battery circuits
or other output connections are prevented from flowing through the equipment mains lead. Such
currents could damage the integrity of the protective earth connection.
The incoming mains earth connects only to the Power Charger enclosure. Both the earth and
enclosure are isolated from all Power Charger output circuits, which helps the above requirement
to be achieved.
The low output voltage from the 12 & 24 volt units does not present an electric shock hazard, but
the high current available can be hazardous by virtue of its potential heating effect, particularly if
batteries are also connected. The installation wiring must therefore be adequate for the currents
involved, with suitable protection from potential fault conditions. Accidental bridging of high energy
circuits by users (eg by jewellery) must be prevented.
