Chapter 2 Installing
Making Ground and Power Connections
Run a 16 AWG green/yellow-striped insulated wire from the SyncServer S6x0
grounding lug to the earth Ground on the rack. The rack grounding method is below.
1. Remove the grounding screw from the rear panel of the SyncServer S6x0.
2. Crimp the customer-supplied UL listed Ring Lug to one end of the 16 AWG wire.
Coat the lug with an electrically conductive antioxidant compound such as
Kopr-shield spray. Use the grounding screw to connect the ring lug to the left side
of the rear panel. The surface of the SyncServer S6x0 rear panel and threads
where the grounding screw attaches must be clean of contaminants and
oxidation.
3. Connect the other end of the 1 mm² / 16 AWG green/yellow-striped wire to earth
ground using local building electrical codes for grounding
.
The suggested method is to crimp the appropriate customer-supplied UL listed
Ring Lug to the other end of the 1 mm² / 16 AWG green/yellow-striped wire.
Remove the paint and sand the area around the screw hole to ensure the proper
conductivity. Coat the connection with an electrically conductive antioxidant
compound such as Kopr-shield spray. Connect this Ring Lug to the rack with
appropriate customer supplied screws and external star lock washers, tightening
to a torque value of 53.45 in-lbs.
4. Using a digital voltmeter, measure between the ground and chassis and verify
that no voltage exists between them.
Recommendation:
Although there are a number of methods for
connecting the equipment to earth ground, Microsemi recommends
running a cable of the shortest possible length from the ground lug to
earth ground.
