DC input terminals
The DC input terminals have a tubular hole with a set screw. A suitable pin type of copper
terminal should, therefore, be used on the cable end.
Do not insert the stranded bare
end of the cable directly into the tubular hole as the set screw will not pinch all the
strands and will thus make only a partial and loose contact.
For thicker cables, a
suitable adapter with pin type of termination should be used.
There should be no stray
wire strands protruding from the terminals as these may produce a short circuit
due to the close vicinity of the plus and minus terminals
Dc input connection
For connecting the DC input, an attached 60 cm cable with cigarette lighter plug and
a battery cable set with battery clips have been provided. These can be used for installation.
NOTE: When using cigarette lighter receptacle in a 12V vehicle, limit the power to
less than 100 watts as the cigarette lighter receptacle wiring in a 12V vehicle is
normally fused for 8 to 10A and the centre pin of the cigarette lighter plug is positive.
Reducing RF interference
To reduce the effect of radiated interference, twist the DC side cables. To furthur reduce
RF interference, shield the cables with sheathing /copper foil / braiding..
Taping battery cables together to reduce inductance.
Do not keep the battery cables far apart. In case it is not convenient to twist the cables,
keep them taped together to reduce their inductance. Reduced inductance of the battery
cables helps to reduce induced voltages. This reduces ripple in the battery cables and
improves performance and efficiency.
AC SIDE CONNECTIONS
Preventing paralleling of the AC output
The AC output of the inverter cannot be synchronised with another AC source and hence,
it is not suitable for paralleling. The AC output of the inverter should never be connected
directly to an electrical breaker panel / load center which is also fed from the utility power/
generator. Such a connection may result in parallel operation of the different power
sources and AC power from the utility / generator will be fed back into the inverter which
will instantly damage the output section of the inverter and may also pose a fire and
safety hazard. If an electrical breaker panel / load center is fed from an inverter and this
panel is also required to be powered from additional alternate AC sources, the AC power
from all the AC sources like the utility / generator / inverter should first be fed to a manual
selector switch and the output of the selector switch should be connected to the electrical
breaker panel / load center. To prevent possibility of paralleling and severe damage to the
inverter, never use a simple jumper cable with a male plug on both ends to connect the
AC output of the inverter to a handy wall receptacle in the home / RV.
