Mains Disconnect Connect the Chassis to the AC Power Line
Safety ground connection
This chassis must be grounded properly for proper operation and safety. Because
the M9514A is connected to the AC mains by a plug/socket connection, a
permanent earth ground must be supplied to reduce the risk of electric shock.
Make a permanent connection from the system rack to protective earth ground.
This connection serves as a redundant Protective Earth Connection to the
primary Protective Earth connection, which is part of the AC power cord. Refer to
Figure 1 . The “Earth (ground) terminal” found at the bottom of a system rack
should be connected by a wire separate from the AC power cord to the Protective
Earth connection at the AC source where the system AC power cord is
connected. The wire must be the same wire size as the protective conductor of
the system AC power cord. The wire may be either a bare conductor or a green
with yellow stripe insulated conductor.
The redundant Protective Earth connection wire should have a correctly sized
wire lug on both ends. The wire lugs should also be sized to fit the “Earth
(ground) terminal” stud or bolt as found on the system rack and for the
Protective Earth connection at the source end of system AC power cord. In some
cases, the Protective Earth connection at the source end of the system AC power
cord will receive the conductor without a wire lug.
