5.1 Grounding the Chassis
The procedure below describes how to ground the chassis.
Earthing
Before connecting the chassis to the earth, read the following:
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.
For Finland: "Laite on liltettava suojamaadoituskoskettimilla varustettuun
pistorasiaan."
For Norway: "Apparatet rna tilkoples jordet stikkontakt."
For Sweden: "Apparaten skall anslutas till jordat uttag."
To ground the chassis:
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.
