Installation Manual

Wiring Connection

The following describes a connection example of Energy Monitoring Relay Interface.

Shield earthing

• The RS-485 communication cable must be earthed on TCS-NET Relay Interface or central controller. It does not have to be earthed on Energy Monitoring Relay Interface. The shielded wire must be crimped with closed end connector. The shielded wire end must be insulated and left open.

Connection of power meters

• Use a power meter with a pulse generator. Connect the non-voltage contact output of the power meter to the Energy Monitoring Relay Interface. An external input circuit is shown below. Input signal is electrically isolated by photo-coupler.
