cAUtion!
the input section of the inverter has large value capacitors connected across the input
terminals. As soon as the Dc input connection loop [Battery (+)
Fuse inverter (+)
inverter (-) Battery (-)] is completed, these capacitors will start charging and will
momentarily draw very heavy current that will produce sparking on the last contact in the
input loop even when the on/oFF switch on the inverter is in the oFF position. ensure
that the fuse is inserted only after all the connections in the loop have been completed so
that the sparking is limited to the fuse area.
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-12125A and PSe-12175A
The dc input terminals on PSE-12125A and PSE-12175A have a tubular hole with a set
screw (h, fig. 7.1). 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 Positive
and negative terminals.
Dc input terminals on PSe-12275A
The dc input terminals on PSE-12275A have nut and bolt connections that will accept
3/8 inch ring terminal (h, fig. 7.2). 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 (i, fig. 7.2).
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.
