Initial Preparation; Electrical Installation; Power Connection; Line Voltage - Wavetek 75 Instruction Manual

INITIAL PREPARATION
2.1 UNPACKING INSPECTION
After carefully unpacking the instrument, visually inspect
all external parts for possibledamage toconnectors, sur-
face areas, etc. If damage is discovered, filea claim with
the carrier who transported the unit. The shipping con-
tainer and packing material should be saved in case
reshipment is required.
2.2 ELECTRICAL INSTALLATION
2.2.1 Power Connection
WARNING
To preclude injury ordeath due toshock, the
third wire earth ground must be continuous
to the facility power outlet. Before connect-
ing to the facility power outlet, examine
extension cords, autotransformers, etc.,
between the instrument and the facility power
outlet for acontinuous earth ground path.The
earth ground path can be identified at the plug
on the instrument power cord; of three ter-
minals, the earth ground terminal is the non-
matching shape, usually cylindrical.
CAUTION
To prevent damage to the instrument, check
for proper match of line and instrument
voltage and proper fuse type and rating.
Line Voltage
Refer to table 2-1 to determine the proper selection of
the line voltage connector. Unless otherwise specified
at the time of purchase, this instrument was shipped from
the factory with the power transformer connected for
operation on a 1 1 5 Vac line supply and with a 318 amp
fuse. If the unit is shipped for 11 5 Vac operation, there
will be no markings or tags on the unit. If the unit is
shipped for 220 Vac operation, there will be a 220 Vac
tag on the rear panel of the unit and a 3/16 amp fuse
installed.
2.2.2 Verifying the Line Voltage
To verify the line voltage (or change the fuse), the
operator must first remove the top and bottom covers.
Remove the top and bottom using the following steps and
figure 2-1.
1. Remove two (2) screws holding top and bottom
covers to rear panel.
2. Slide both covers (together as a unit) to the rear and
remove from the chassis assembly.
Figure 2-1. Top and Bottom Cover Removal
After the covers have been removed, the line voltage can
be checked by viewing the voltage label through the
inspection hole as shown in figure 2-2.
