If longer cables are required only use suitably insulated
automotive battery cable according to the following table.

It is recommended that a circuit breaker or high current fuse
be placed in the DC positive (+) line close to the battery.

It is also recommended that a heavy duty battery switch with
a current rating higher than the fuse (or combined fuses) be
fitted in the DC positive (+) line close to the battery to allow
the supply to the inverter to be switched off, this can also be
achieved by using a circuit breaker which has a trip facility.
Positive and negative cables should be run close together to
reduce cable inductance, and be protected from damage by
corrugated conduit.
GROUND CONNECTION
The chassis ground lug must be connected to a grounding
point. In a vehicle, connect the chassis ground lug to the
vehicle’s chassis. In a boat connect to the grounding system
of the boat. In a fixed location connect to the ground.
OPERATING TIPS
Most electrical tools, appliances and audio/video
equipment have a label indicating power consumption in
amps or watts. Add up the power consumption in those items
you will be using simultaneously, keeping total below the
8ZED Inverter size. If the power consumption is rated in
amps, multiply by the AC volts (220/230/240) to determine
the wattage. For example, a television rated at 0.9 amps will
use approx 99 watts. For more information regarding the
typical wattage draws of many appliances, refer to 8zed.com.
Resistive loads, such as incandescent lights, are the easiest
for the inverter to drive, though larger resistive loads, such as
electric stoves or heaters, require more power. Please make
sure you choose the right 8ZED Inverter to suit the
application you need in order to power the appliance
continuously. Inductive loads, such as TV’s and stereos (any
device with a coil or a transformer in it) require more current
to operate than a resistive load of the same power rating.
Induction motors (motors without brushes), as well as some
televisions, may require 2 to 6 times their power rating to
start up. This condition may require repeated “ON/OFF,
ON/OFF, ON/OFF” switching of the power switch on your
8ZED Inverter in order to get them started. The most
demanding are those that start under load, i.e. compressors
and pumps. Since motor and television characteristics vary
widely, only experimentation will determine if a specific load
can be started and how long it can be run.
There are no standards for “surge power” partly because it
can not be simply represented by a single sample number.
Though our 8ZED Inverters can provide power up to 6000W
(depending on the unit you purchase) for a short period,
experimentation is the only method of determining whether it
can handle the surges generated by a particular load.
IMPORTANT NOTE: The 8ZED 120W to 1200W
Inverters won’t operate most appliances designed to produce
heat such as hair dryers, coffee makers, irons, heaters and
toasters. The current use of most of these exceeds 1200 watts,
far beyond the capacity of the units listed above. The inverter
may be used either while the engine is running or turned off.
However, the inverter may not operate while the engine is
starting, since the battery voltage can drop substantially
during engine cranking. The 8ZED Inverter draws less than
1.3 ampere from the battery when it is not supplying power
to the load. In most cases, the 8ZED Inverter may be left
connected to the battery when it is not in use, since it draws
so little current. If the vehicle will not be used for several
days, disconnect the 8ZED Inverter from the battery.
CONNECTING APPLIANCE &
RUNNING INVERTER
• Connect the appliance AC plug to the inverter AC
outlet socket.
• Switch the inverter “ON”, the Green power light will
illuminate to indicate operation.
• Turn the appliance “ON”, if the appliance is fitted with
an “On/Off” switch always switch the inverter on
before switching the appliance on and always turn the
appliance off before switching the inverter off.
• When not in use turn the inverter off.
LOW BATTERY ALARM
An alarm will sound when the voltage of the battery drops
to 10.5 volts. This indicates that the battery requires
recharging. The user should stop operations at this time,
since the 8ZED Inverter will shut down automatically when
battery voltage drops to 10.0 volts.
