Using proper DC cable termination
The battery end and the inverter end of the cables should have proper terminals that will
ensure a firm and tight connection.
DC input terminals on PSE-24125A and PSE-24175A
The DC input terminals on PSE-24125A and PSE-24175A have a tubular hole with a set
screw. A suitable pin type of copper terminal should, therefore, be used on the cable end.
(A pair of pin type terminals has been provided. Crimp these terminals on the inverter
end of the cables)
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 terminals on PSE-24275A
The DC input terminals on PSE-24275A have nut and bolt connections that will accept
3/8 inch of ring terminal. Use appropriate compression lugs or aluminium box lugs.
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
After the DC input cables have been connected, cover the terminals with the plastic
protective covers provided.
Reducing RF interference
To reduce the effect of radiated interference, twist the DC side cables. To further 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.
