3.3.1 Earthing (Grounding) the Chassis
Read the following earthing (grounding) warning notice before connecting the chassis to the
earth:
Earthing
Safety Earth
Intrinsically, the chassis must be safety-earthed using an equipment-earthing
conductor. Do not depend on locknut-bushings and double-locknuts for
bonding. Use the earthing hardware provided with the chassis.
Earthing Electrode
The chassis must be earthed to a stable local earth reference. The chassis
earth terminal should be connected through a separate earth wire (6-8 AWG
recommended) to the rack's earthing. The earth connection’s resistance must
not be greater than 0.1 Ohm. Verify that the rack’s earthing is properly
performed.

To connect the earthing cable:
„
Permanently connect the chassis to a suitable earth with the earthing screw on the
rear connector panel using a one-hole G-32 lug and a 6-8 AWG wire.
