Warning
To avoid shock hazard, connect the factory supplied three-
conductor line power cord to a properly grounded power
outlet. Do not use a two-conductor adapter or extension
cord; this will break the protective ground connection.
Use the rear-panel CHASSIS GROUND terminal for a
protective grounding wire if there is any question about
the effectiveness of instrument earth grounding through
the line power cord ground wire.
The CHASSIS GROUND terminal is internally grounded to the chassis. If the 5522A is the location
of the ground reference point in a system, this binding post can be used for connecting other
instruments to earth ground. Refer to “Connecting the Calibrator to a UUT” in Chapter 4, “Front
Panel Operation” for details
The AC Power Input Module provides a grounded three-prong connector that accepts the line
power cord, a switch mechanism to select the operating line voltage, and a line power fuse. See
Chapter 2, “Preparing for Operation” for information on selecting the operating line voltage, and fuse
rating and replacement information.
