Safety Ground
Safety Ground
The safety ground cable is attached with an M4 X 12 binding head screw through
the lug, with an external toothed M4 lock washer located between the lug and the
chassis.
!
Caution: Route the cable so that it does not obstruct the latching of the key-
board.
!
Caution: Use fasteners of the correct length to prevent damage to underlying
equipment. See "Fastener Reference" (page H-1).
!
Warning: The improper connection of the safety ground can create a shock hazard. The G50
and the G60 S contain hazardous voltages that can range from 90 Vac to 264 Vac. These volt-
ages can cause serious injury or death. Verify that the safety ground is attached using the cor-
rect hardware and that the installation screw is tight.
