Connection to AC power supply
These units are available for operation
either at 220-240V or 110-120V.
It is not possible to change the voltage
setting.
Check that the voltage printed on the serial
number plate, located at the rear of the unit,
is correct for the local a.c. power supply
voltage.
220-240V Version
This version of the unit has an IEC
mains input socket fitted in the rear panel
and is supplied with a separate a.c. power
supply cable, which is fitted with an IEC
connector and plug suitable for the country
for which it is supplied.
There are two supply voltage fuses located in
the drawer below the mains input socket and
may be removed using a small screwdriver to
gain access to the fuses.
The correct fuses are 1.25inch x 0.25inch
ceramic rated at 10 amps.
110-115V Version
This version of the unit has its power
supply cable permanently fixed to the rear of
the unit. The fuses are located in two panel
mounted fuse holders, turning the cap with a
screwdriver gives access to the fuses.
The correct fuses are 1.25inch x 0.25inch
ceramic rated at 20 amps.
It is recommended that the unit is tested with
the cable supplied by Grant Instruments.
However, if this is not possible, ensure that
the cable used has the correct current rating
and that its earth (ground) conductor is
continuous.
