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:

1Connect the power cords of all Option 11C Mini system equipment to the outlets on the transformer secondary.

2Secure 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.
