The power source must provide > 10.0
and < 15.5 VDC and must be able to sup-
ply the necessary current to operate the
load. The power source may be a battery
or a well-regulated DC power supply. To
obtain a rough estimate of the current (in
amperes) the power source must deliver,
simply divide the power consumption of
the load (in watts AC) by 10.
example:
lf a load is rated at 100 watts AC, the
power source must be able to deliver:
100 / 10=10A
The inverter will provide you 230 VAC,
50 Hz when powered by a 12 VDC source
such as is found in a vehicle. This manual
does not describe all of the possible types
of battery configurations, battery charg-
ing configurations and battery isolation
configurations.
GRoUnDInG
for safety, the metal chassis of the inverter
is required to be grounded to the earth
ground or to the other designated ground
(for example, in a mobile rV, the metal
frame of the rV is normally designated as
the Negative DC ground).
Internally, the metal chassis of the inverter
is bonded (connected) to the Negative
DC input terminal (8). When the unit is
operated in a Negative Grounded Vehicle
System (the Negative of the vehicle bat-
tery is bonded to the metal chassis of the
vehicle), the metal chassis of the inverter
will be automatically bonded to the Vehi-
cle Chassis Ground.

WARnInGS
If the inverter is not being used in a vehi-
cle, please ensure that the negative of the
battery is firmly bonded to earth Ground
(through water pipe / Ground Rod / other
earth grounding arrangement). this will
ensure that the chassis of the inverter is
firmly "grounded". Use a # 8 AWG insu-
lated stranded copper wire for the above
bonding.
Prongs (1A) and (1B) of the AC output
receptacle (1) are isolated from the metal
chassis of the inverter and the Vehicle /
earth Ground. the grounding prong (1C)
is connected to the Leakage Detection
and Shutdown Circuit. this implementa-
tion and internal circuit design results
in elevated voltages of 80 to 150 VAC of
prongs (1A) / (1B) relative to prong (1C) or
to the chassis. Do not touch prongs (1A)
or (1B).
Connecting output from prongs (1A) or
(1B) to chassis or ground will result in
shut down due to activation of leakage
protection circuit.
Do not connect to AC distribution wiring
where the neutral is bonded to earth
ground. Inverter will shut down due to
leakage protection
