A disconnect
switch
and fuses must be installed
in the input circuit
between
the power source and the generator
set.
Route the input
leads (cable or cm-
duit)
carefully
so they
will
not be a hazard

If leads are not identified,
connect
at random and use a phase rotatim
meter
to determine
proper phase sequence.
If out of phase,
change
any two input
leads to correct,
If a phase rotation
meter
is not available,
check
for correct
rotation
as follows:
(a)
Remove
cne of the canopy
