Receptacles
Receptacle requirements are as follows:
•
When mounted on the wall, they must be installed within reach of the
cabinet power cords (the power cord from each cabinet is 9 ft 10 in. [3000
mm] long).
•
All receptacles served by the secondary must be of the isolated ground
type
•
The ground prong of each outlet must be connected by an insulated
conductor to the system SPG
If the transformer has an isolated secondary ground lug, use it as the Single
Point Ground (SPG). If it doesn’t, use the chassis ground of the transformer
as the SPG.
Transformers with pluggable power cords
See the following for installation instructions.
1
Connect the power cords of all Option 11C Compact system
equipment to the outlets on the transformer secondary.
2
Secure an insulated conductor between the ground lug on the main
cabinet of the Option 11C Compact system and the SPG lug on the
transformer. Place a “DO NOT DISCONNECT” tag on it.
Do not fasten or tie this conductor to the power cable feeding the
NTMW11 power supply.
Note: All equipment associated with the Option 11C Compact system
should be powered exclusively from the secondary of the transformer
and grounded to the secondary isolated ground lug. Do not connect
equipment unrelated to the Option 11C Compact system to an isolation
transformer powering it.
