Series 8500A Peak Power Meters
☛ NOTE: The 8500A may be furnished with the PC-oriented voltage selector and fuse holder
described next, or the VDE-approved fuse holder described in the following pages. Refer
to the appropriate type of voltage selector and fuse holder for your power meter.
CAUTION
The instrument may be damaged if you turn it on while the voltage selector and
fuses are incorrect for the applied line voltage.
The power meter is supplied with a three-conductor NEMA type power cord for connection to the power
source and safety ground, as illustrated in Figure 2-1. The current carrying conductor is black and its
return is white. The green wire of the power cord is for connection to earth ground. The instrument will
be properly grounded if the plug is connected to a properly installed three-prong receptacle. If a
three-prong to two-prong adapter is used, be sure that the pigtail lead of the adapter is earth-grounded.
WARNING
The safety ground is connected directly to the chassis. If a 3-to-2 wire adapter is
to be used, be sure to connect the ground lead from the adapter to earth ground.
Failure to do this could cause the instrument to float above ground, posing a shock
hazard.
