1. INTRODUCTION
Thank you for purchasing a “Power Trolley 8”
Your Power Trolley is a versatile unit specifically designed to provide power
when normal Utility power fails. It can provide quick-acting emergency power
for many situations where either power has failed or when a ready source of
portable mains power is needed for small businesses, service professionals
and home use for powering TV’s, DSTV Decoders, M-Net Decoders, Lights,
Alarm Systems, Laptop Computers, Desktop Computers, DeskJet Printers,
Radios, Hi-Fi Systems, Security Systems, Cash Registers, PABX systems,
modems, hubs, routers, etc.
It is very user friendly and has the added benefit of being emission-free and
noiseless. It requires no installation, virtually no maintenance, and is
inexpensive to operate.
It has a number of advanced features allowing you to:
See at a glance the condition of the unit with easy-to-understand
LED indicators
Have virtually instantaneous back-up power when a mains power
failure occurs –very smooth changeover.
Easily wheel the unit to where it is needed
Tip or tilt or turn over the unit without fear of spilling acid from the
fully-sealed internal batteries
Smooth sine–wave power –no worries about interference with
electronic equipment
This manual describes the simple steps to use the unit and explains to you the
operation of the “Power Trolley 8”.

2. USING THE POWER TROLLEY
Moving the unit to where you want to use it is easy. It comes with a retractable
handle exactly the same as you have on your “carry-on” airline suitcase. Push
the button on the handle, lift and fully extend the handle. Put your foot on the
centre axle between the wheels, tilt the unit to about 45° and you’ll find the
unit easy to wheel wherever you need it. If you have to lift it into the boot of a
car, for instance, it is easier with two people using the white handles on both
sides.
Handling the trolley
Avoid rough terrain and do not twist the handle

3. FOR HOW LONG WILL YOU GET POWER BACKUP?
The Power Trolley 8 comes with internal batteries fitted.
The power available is load dependant. Depending on what is plugged into
the unit, up to 7 hours’backup is possible with the ‘built-in’ battery with a
100W load.

4b. CONNECTING TO THE POWER TROLLEY
Supplied with the Power Trolley is a 2,5m 3-pin 15A cable with a 3pin ‘kettle
connector’. This cable is for the built-in battery charger in the Power Trolley
and supplying mains while on standby.
1. Check the rating label on the rear panel to be sure that the line input
voltage rating is correct. Normally 220V –230VAC / 50Hz.
2. Plug the supplied 3-pin kettle connector to the provided socket and then to
a wall socket AC power outlet. Leave the cable permanently plugged-in
to the mains unless you wish to transport the unit. Do not leave the unit
disconnected from the mains supply for longer than 2 months.
3. If you are using the equipment for the first time, allow the unit to charge its
internal batteries for at least 12 hours.
4. Connect the equipment to one or both of the 15A output sockets.
5. Press the “ON-OFF” switch on the front panel to ON (I) and check after a
few seconds if the green “ON-LINE” LED is lit only.
6. Check that the “FAULT/OVERLOAD” is not lit – if it is, you will need to
reduce the load connected to the AC outlet.

NOTE :
If the unit is in “ON-LINE” mode, i.e. running off of the AC mains, pressing the
“TEST” button momentarily transfers the unit to run off its internal batteries to
do a check on the condition of the batteries. If the unit is in “ON BATTERY”
mode, i.e. running off of the internal batteries, pressing the “TEST” button
momentarily causes the unit to silence the buzzer.

6. RS232 INTERFACING WITH THE POWER TROLLEY
The Power Trolley 8 provides communications signals such as Power Failure,
Low Battery and External Shutdown via an RS232 DB9 cable connection to
the user’s computer. The communication protocol is:
PIN
ASSIGNMENT
2
PF : Power Failure Alarm (Closes an internal relay contact to indicate
a power failure and the Unit is in battery mode)
4
Common pin. (Signal ground for pin 5 and pin 2)
5
LB : Low Battery Alarm (Closes an internal relay contact to indicate
that battery voltage is low and shutdown is imminent)
6
RS232 RXD –Receive Data / External Shut-Down. A +5V/+12V signal
held down for 0.5 sec. when the Unit is in battery back-up mode, will
shut the Unit down 20 seconds later. The Unit will auto-restart when
line voltage recovers.

7. GENERATOR USE
If the “Power Trolley 8” is powered via a small, good quality generator, a
Genset of at least 2.5 - 3 KVA should be used. The Genset must have either
a mechanical or electronic governor / regulator installed.
Cheap small imported generators from the east should be avoided as the
output voltage is often not regulated and can damage your Power Trolley 8.
8. TROUBLESHOOTING
Problem
Check
I’ve plugged in the equipment I want
to use but there’s no power output.
Have you checked that you’ve plugged the unit
into a wall socket and that the switch is ON? Is
the Power Trolley internal battery fully charged?
Check the “BAT WEAK” LED. Is it lit?
Have you switched the “Master Switch” to ON? Is
the “ON LINE” green LED ON? Is the external
Resettable CB pushed in?
I’ve plugged in the equipment I want
to use but there’s poor power
output, the buzzer keeps beeping.
The internal battery is correctly
charged and the
“Master Switch” is ON.
Check the status of the LOAD
LEVEL LED indicators. Is the OVERLOAD LED
lit? Disconnect the equipment connected to the
Power Trolley. Reconnect the output equipment
one –by - one until you reach 100% LOAD.
The internal battery is correctly
charged, the “Master Switch” is ON
but neither the ON LINE nor ON
BAT indicators are lit.
If no LED is lit an internal problem has occurred
and the system must be sent to your nearest
Dealer to be checked out
The Power Trolley was working then
just stopped. Neither the ON LINE
nor ON BAT LED’s are lit.
The “FAULT” LED is lit.
You’ve got a problem with the internal protection
of the Power Trolley. Try switching OFF then ON
the Master Switch with the AC output plug(s)
removed. If the unit does not come back on again
you’ll have to take the unit to your Dealer to be
checked out.
The Power Trolleys are sophisticated electronic microprocessor-controlled
equipment and we recommend you do not try to open the system by yourself.
The unit contains internally high and dangerous voltages which can lead to
injuries if not handled carefully. Only let a fully qualified & authorised
electronic technician work on the system.

PRECAUTIONARY ADVICE
The manufacturer has taken all possible precautions to protect this unit
against overload, over temperature, reverse polarity, etc. If excessive
overload, excessive temperature and/or reverse polarity are applied to the
unit, the protection circuit will work but with excessive mishandling they may
give in after a while and this can cause damage to the unit. It is therefore up to
the user to connect the correct loads and to use the unit within the specified
parameters. The user must also ensure that no reverse power is fed back into
the output sockets of the system.
The unit must not be kept or operated in direct sunlight and should never be
placed in a moist or wet environment.
9. OVERLOAD RESET
You’ll see a ‘resettable’ circuit breaker on the side of the Power Trolley 8. This
is an additional safety device which will trip if you substantially overload the
unit. Disconnect the equipment you’ve connected to the AC connection
sockets, reset the breaker and try connecting with less equipment connected
to the unit.
