2.3Grounding
Proper,
If conduit or other wireway is used as the grounding means, adequate electrical continuity must be maintained at all conduit connections. The use of isolating bushings with a metal conduit can be a safety hazard and is not recommended.
In accordance with the NEC, only one equipment grounding system may be used in a single build- ing. As such, both input power sources should be referenced to a common building grounding elec- trode system. The SmartSwitch input equipment grounding conductors should not be the only grounding interconnection between the two input power sources.
The SmartSwitch switches all input phase and neutral conductors to maintain complete isolation of the two input power sources. A common
2.4Control Wiring Connections
The SmartSwitch includes relay output contacts and
To facilitate connection to the relay contacts, the mating connector with short pigtails of wires is supplied with the SmartSwitch. Relay contact ratings are 1 amp, 125 VAC or 30 VDC maximum. Contacts close on the indicated switch condition. The relays are located in the removable electron- ics module. Contacts are not operational with the electronics module removed.
