Sun StorEdge Expansion Cabinet Installation and Service Manual • July 2000
Caution –
The expansion cabinet has a high leakage current to ground. Strictly
observe all caution and note statements to reduce the risk of electric shock.
Note –
If the appropriate mating receptacle is not available, the connector may be
removed from the cord. The cord may then be permanently connected to a dedicated
branch circuit by a qualified electrician. Check local electrical codes for proper
installation requirements.
Note –
Cable ties provided with the expansion cabinet can be used as cable
restraints. For each cable, pass a cable tie through one of the slits located along the
base of the cabinet. Secure the cable in the cable tie.
Repeat this procedure for the other power sequencer.
2.3
Connecting the Ground Strap
Caution –
The installer must install an insulated grounding conductor as part of the
circuit supplying power to the unit or system. This conductor must be of identical
size, insulation material, and thickness to the neutral grounded and hot ungrounded
branch-circuit supply conductors, but green (with or without yellow stripe[s]).
The grounding conductor described in the above caution statement must be
grounded to either of the following:
■
Earth at service equipment
■
Supply transformer or motor-generator set (if supplied by a separately derived
system)
The outlets in the vicinity of the unit must be of the grounding type, and the
grounding conductors for these outlets must be connected to earth ground.
Connecting the ground strap between the expansion cabinet and the cabinet nearest
to it prevents ground loops between the two cabinets and keeps data errors from
occurring.
1. Locate the 2-meter grounding strap from the kit that was shipped with your
expansion cabinet.
