Unpacking Your Tool
• Carefully unpack and inspect your new tool. Familiarise yourself with all
its features and functions
• Ensure that all parts of the tool are present and in good condition. If
any parts are missing or damaged, have such parts replaced before
attempting to use this tool
Before Use
Installing your inverter
IMPORTANT: The inverter does not require a connection to earth in a vehicle
so ensure the inverter is kept electrically isolated from the vehicle chassis.
• Always read the vehicle's manual in combination with these instructions
when installing an inverter
• Always mount the inverter level and horizontal so that the internal fans
extract the heat with maximum efficiency
• The inverter should ideally be located as close as possible to the battery
but not placed in the engine bay or battery compartment
• Ensure the position of the inverter allows for easy access to the On/Off
Switch (4)
• Do not use the inverter in a dirty or dusty environment. It is important the
inverter has good ventilation and the fan outlets, vents and mains socket
are free of dust and debris
• Always position the inverter away from direct sunlight and other heat
sources. Only use the inverter when the ambient air temperature is
between 10-30˚C
• Allow adequate ventilation by ensuring there is always at least 25mm
clear space around the inverter. Do not place anything on top of the
inverter
• When used in a vehicle, the inverter should only be used with 12V DC
negative earth electrical system. Use with any other type of vehicle earth
system may be dangerous and could cause permanent damage to the
inverter and other electrical components
Connecting to a 12V car cigarette lighter socket
• Remove the knobs of the 12V Connectors (6) and put the ring terminals
at the end of the 12V Cigarette Plug Cable (9) over the pins of the
12V Connectors. Ensure the ring terminal in red goes to the red 12V
connector, and the black ring terminal goes to the black connector. Refit
the knobs

Note: Car cigarette lighter sockets have limited current output. In the event
a device fails to operate, it is possible direct connection to the battery may
allow it to function due to higher start-up current being available.
Connecting to a battery
WARNING: When working next to or moving lead acid batteries, ensure
you are wearing splash-resistant safety goggles and electrically insulated
gloves.
Notes:
• If you wish to replace the supplied 12V cables with longer cables,
connect cables that are suitable for the sustained inverter current
demands, not peak/surge (see Specification). Also make sure the
insulation of the cable is correct for the environment the cables will be
used in
• If fitting an inline fuse to improve protection against short circuits and
overloads, connect inline to the cable that attaches to the inverter's 12V
positive terminal. Select a suitable fuse based on the maximum sustained
input current of the inverter, and choose a fuse at the closest value above
this. So an inverter rated at 93A would need a 100A continuous (anti-
surge/time delay) rated fuse. Do not use a quick or fast-blow-type fuse
due to the peak current demands of AC devices when they are started.
• When batteries need charging in a stationary installation and the battery
charger used allows for charging multiple batteries simultaneously,
make sure the inverter is switched off or disconnected while charging to
prevent possible damage to the inverter and battery charger. Check the
instructions supplied with the battery chargers for exact information
1. Switch the On/Off Switch (4) to the off position
2. Connect the 12V Cables (8) to the battery, connecting the red crocodile
clip to the positive first and then the black crocodile clip to a negative
earth point away from the battery
If you are connecting multiple batteries in a stationary installation, ensure
they are connected in parallel (Fig. A). Do not connect in series as the
inverter and possibly the batteries will be damaged. Parallel requires all
negative battery terminals to be connected to the negative terminal of the
inverter and all positive battery terminals to be connected to the positive
terminal of the inverter.
3. Remove the knobs of the 12V Connectors (6) and attach the free ends
of the 12V cables. Connect the black 12V cable to the Negative
Connector (-) and the red 12V cable to the Positive Connector (+). Tighten
the knobs. Check the cables are connected to the correct connectors.
Connecting to the Positive Connector (+) of the inverter should be the
final connection made. It is important that the polarity is correct as the
inverter's internal fuses will be blown by incorrect polarity
Operation
Connecting a mains device
WARNING: This inverter is not compatible with devices that have a
capacitive power supply; due to their design they will not work with the
simulated AC voltage (modified sine wave) of this inverter. Such power
supplies are no longer sold from new in Europe due to their reliance on pure
sine wave AC and are fairly rare. They do not meet current European safety
standards but if you suspect your device has such a power supply, make
sure you monitor the device when first connected. If it is a battery charger
that contains a rechargeable battery of any type it is recommended not to
try it due to the possibility of damage to the batteries.
WARNING: If the inverter is constantly running at a very high temperature
or is shutting down in use, it is possible the device connected to the inverter
is not ideally matched and should not be connected. Always monitor the
inverter and mains device when connected for the first time for the first 5
minutes or so to ensure both are working correctly at normal temperatures,
then check on the device every half hour for the first 2 hours. Once the
device is confirmed as compatible mark it so its compatibility is recorded.
WARNING: The 230V Universal Mains Socket (5) fitted to the inverter is a
universal type which accommodates a wide range of world mains plugs.
It is important when using devices fitted with a non-UK or European plug
that you check the device is compatible with 230V 50Hz. This is especially
important for devices intended for the US market; these will normally be
120V 60Hz only and must not be connected. Only if the rating label of the
