Chapter 3 — System and site requirements
Receptacles
Receptacle requirements are as follows:
• When installed on the wall, install receptacles within reach of the chassis
power cords.
• 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 SPG. If
it does not, use the chassis ground of the transformer as the Single Point
Ground.
Installing an Isolation Transformer
Transformers with pluggable power cords:
1 Connect the power cords of all Option 11C Mini system equipment to the
outlets on the transformer secondary.
2 Secure an insulated conductor between the ground lug on the Main
Chassis of the Option 11C Mini 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 Option
11C Mini.
Note: Power all equipment related with the Option 11C Mini from the
secondary of the transformer only. Ground all equipment to the
secondary isolated ground lug. Do not connect equipment that is not
related to the Option 11C Mini system to the isolation transformer that
powers it.
