AWG2021 Service Manual
This section describes how to prepare the AWG2021 Arbitrary Waveform
Generator for use. The information describes these items:
H Proper operating environment
H Checking power cord and line voltage configurations
H Checking the fuse
H Power-on and power-off cycles
Before installing the AWG2021, note these precautions:
WARNING. To avoid equipment failure and potential fire or personal shock
hazards, do not exceed the maximum rated operating voltage of 250 V between
the voltage-to-ground (earth) and either pole of the power source. The AWG2021
operates from a single-phase power source and has a three-wire power cord with
a two-pole, three-terminal grounding plug. Also, before making connection to the
power source, be sure the AWG2021 has a suitable two-pole, three-terminal
grounding-type plug.
To avoid personal shock hazard, do not contact conductive parts. All accessible
conductive parts are directly connected through the grounding conductor of the
power cord to the grounded (earthing) contact of the power plug. The AWG2021
is safety Class 1 equipment (IEC designation).
To avoid personal shock hazard, do not defeat the grounding connection. Insert
the power input plug only in a mating receptacle with a grounding contact where
earth ground has been verified by a qualified service person. Also, for electrical
shock protection, make the grounding connection before making connection to
the AWG2021 input or output terminals.
