Installation Procedure cont.
Ground Wiring
This product must be properly grounded to the facility’s ground bus. Failure to do so is dangerous to personnel and may result in
equipment malfunction.
10. Crimp ground lug to a #6 AWG stranded copper wire. One #6 AWG ground wire is the minimum requirement for 240Vac single
phase input to the panel.
11. If required, lightly coat anti-oxidant on contacting surface of the ground lug. (The ground lug is located just left of the access panel
shown in Figure 3.)
12. Fasten lug to panel using the provided M6 KEPS nuts and flat washers. Tighten to 50 - 55 inch pounds (~6.2 Newton meter).
Secure ground wire to rack bonding bar (RBB).
13. Alternate ground lug can be found inside the rear access panel (see Figure 3b). This dual lug will support wire size from 14 AWG
to 2/0 AWG. Ground lug for incoming branch power can be found inside the rear access service wiring panel (see Figure 3b). This
lug will support wire size from 14 AWG to 4 AWG.
