If the low battery alarm sounds when the battery is fully

charged, follow these steps for correcting the lack of output

power: Reduce the load on the inverter and keep the voltage

above 11.5 volts to maintain regulation. The alarm will sound

when the inverter is overloaded, or if there is an excessive

voltage drop between the battery and the inverter.

NOTE: The alarm may sound momentarily when the unit is

being connected to, or disconnected from, the power source.

This is normal and does not indicate any problem.

INDICATORS AND CONTROLS

PROTECTION FEATURES

Your 8ZED Inverter circuitry constantly monitors the

following hazardous conditions:

A.) Low Battery Voltage – This condition is not harmful to

the inverter, but could damage the power source. An

audible alarm is sounded when input voltage drops to

10.5 volts. When the condition is corrected (i.e.

alternator charges battery) the unit may be restarted.

B.) Short Circuit - Reverse polarity or short circuit

condition of the load will usually result in opening of

the short circuit protection and blowing the three 35

amp fuses.

C.) High Temperature – When the temperature of the

internal heat sinks reaches 66 degrees C (150 degrees

F), the solid state temperature sensor located in the

8ZED Inverter will automatically shut down the unit.

Once it is allowed to cool, it may be restarted.

TROUBLESHOOTING GUIDE / FAQ

Q. The inverter will not run my appliance even though

the listed power is less than the inverter size

A. Electrical appliances can be separated into three loads

by the way they draw energy (current) from their power

supply. These loads are "Resistive", "Inductive" and

"Capacitive" appliances. Some appliances may draw all three

types of power, in which case all should be considered.

•

Resistive Loads such as normal incandescent lights

(wire filament) always draw a constant power (watts)

from the power supply, that is a 100 Watt light will draw

approximately 100 Watts from the power supply at all

times. Resistive loads are the easiest appliances for an

inverter to run.

•

Inductive Loads such as a fridge (electric motor) require

a large rush of power (surge current) to start and then

usually draw a more constant power once running.

Inductive

loads

contain

transformers, ballasts, solenoids). When the power is

first turned on these coils of wire draw a large surge

current which forms the magnetic flux which allows

these appliances to work. The magnetic flux is a kind of

stored energy. Most common inductive appliances are:

fridges, air compressors, transformers, pumps, power

tools & fluorescent lights. These appliances can draw 2-6

times their normal running power to start up. To run a

200 Watt fridge you may need a 600 to 1200 Watt 8ZED

inverter.

•

Capacitive Loads such as TV's may require a large

surge current to start only when they have not been used

for a while. This is often due to large capacitors in the

power supply that must be quickly charged when the

appliance is turned on. If the appliance is not used for a

few days these capacitors slowly go flat. Resetting the

inverter a couple of times may allow these appliances to

work.

•

Some appliances such as large fridges, air conditioners

and other pump driven appliances have extremely high

start up currents, because they have an inductive motor

that must start under load. These appliances are not

recommended for use with an inverter. They should be

Q. Why is it important to make sure that the battery

leads are not connected back to front?

A. The 8ZED inverter uses highly developed electronics to

convert DC battery power to AC mains power. If you

accidentally connect the inverter to the battery incorrectly a

large current will be drawn by the inverter which will blow

the protection fuses, as this occurs some of the high current

could damage the sensitive electronic components. Because

of this risk it is important to always double-check the battery

polarity before making any connections.

Q. Why do some power tools not work properly?

A. Some newer power tools use PWM variable speed

controllers to vary the tool's speed as the trigger is squeezed.

These power tools switch the power on and off very quickly

in a similar way to how the inverter works. Because of this,

some may not function properly with the inverter's modified

sine wave output.

Q. Can I connect lights with dimmers to the inverter?

A. Older light dimmers may function fine but most newer

light dimming circuits are designed for household sine wave

AC power, these may not work properly with modified sine

wave inverters.
