Before Use
Installing your inverter
WARNING: If you have any doubt about your ability to install an inverter,
have it installed by or consult a qualified electrician.
WARNING: If the inverter is modified to bond neutral to earth, this will
invalidate the suggested earth wiring in this manual, including connecting
earth to a vehicle's 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 can be mounted
upside down as long as the body remains level and horizontal. Use the
Mounting Holes (6) to secure to a surface. The earth pin connection of the
universal socket is connected to the inverter's external case. The inverter
does not require a connection to earth in a vehicle so ensure the inverter
is kept electrically isolated from the vehicle chassis
• 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 (5)
• 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 10-27˚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
• There are Mounting Holes (6) on the case body for securely mounting the
inverter with screws or other fasteners.
• In a stationary location, the battery or battery bank MUST be connected
to a ground rod (a metal rod driven into the earth) or other earthing point
(Fig. B)
• 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 battery
WARNING: When working next to, or moving lead acid batteries ensure
you are wearing splash resistant safety goggles and electrically insulated
gloves.
WARNING: The maximum input current of this inverter (95A) exceeds the
output of most alternators fitted to cars and light vans, which normally have
a current output of approximately 60-70A. This inverter used to maximum
capacity for an extended duration, even while the engine is running, will
require current well beyond the spare current capacity of the alternator,
and will discharge the battery until fully discharged and the vehicle cannot
be started.
IMPORTANT: Normal automotive (SLI) batteries are not recommended
for use with this inverter if the inverter is used at its maximum output for
extended periods - especially if the inverter is used in a stationary position
that does not benefit from having a vehicle alternator providing part of the
current requirements. Recommended battery types are deep cycle (leisure)
or traction batteries. These are purposely designed to be depleted fully at a
low to medium rate and recharged frequently, but do not provide the peak
current output of automotive batteries that is required for starting a vehicle.

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
• To use this inverter at full capacity in a vehicle may require fitting of a
higher performance alternator
• When connecting multiple batteries in parallel, ideally all batteries should
be the same type, manufacturer, age and capacity. This will help provide
the same level of current and runtime across all batteries and mean they
will age and can be replaced at the same time with minimal waste of
battery life. A worn battery with reduced capacity is the weak link in a
battery bank and prevents the full benefits of a bank being realised
• It is safer to use normal automotive (SLI) batteries in a parallel
arrangement with an inverter as the sustained high discharge rate is
shared across multiple batteries. This can help such batteries last longer,
which otherwise may wear out very quickly when used individually with
inverters
• 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 95A 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. A
suitable fuse and fuse holder are available as Maxi blade type or Mega™
fuses for higher values
• 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 (5) to the off position
2. Connect the 12V Cables (9) to the battery as shown in Fig. A for vehicles
or boats, or Fig. B for a stationary installation. Make sure the cables are
not shorted together
3. If you are connecting multiple batteries in a stationary installation, ensure
they are connected in parallel (Fig. C). 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. Double check the batteries are correctly
connected before connecting to the inverter
4. Remove the knobs of the 12V Connectors (7) and (8) 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
