Connecting the
Mainframe to a
Permanent Earth
Ground
The mainframe must be connected to a permanent earth ground for line
frequencies greater than 66 Hz. This connection is made on the back of the
mainframe:
1. Connect a 16 AWG (1.3 mm or larger) wire to the PEM nut shown in
Figure 1-1. The wire must be green with a yellow stripe, or bare (no
insulation). Use a m4 x 10 screw, grounding lug, and toothed washers
(or toothed lug) as shown in the Figure.
2. Attach the other end of the wire to a permanent earth ground using
toothed washers or a toothed lug.
WARNING
For protection from electrical shock when operating at
frequencies greater than 66 Hz, connect the chassis ground
terminal to permanent earth ground.
AVERTISSEMENT
Risque de Choch èlectrique. Si la frèquence du secteur est
supèrieure à 66 Hz, relier la borne de masse du chassis à une
prise de terre fixe.
