Remote Power Cycle Wiring
Wiring Procedure: RAc IR302 with Remote I/O to Cycle Power for a GRIDlink IPm
This procedure outlines how to wire and configure the IR302 to control power cycling for a GRIDlink IPm device.
Follow these steps carefully to ensure proper functionality.
Power and I/O Requirements
It has been found that the I/O output is insufficient to directly drive the GRIDlink IPm because the 24VDC supply is reduced to 12V and there is insufficient current available. A solid state interposing relay will be required.
Wiring Diagram
Mount the Relay
Mount the relay to the backplane with self tapping screws.
Connect the RAc IR302 to the Relay
Connect the com terminal to terminal 4 on the relay.
Connect the IO 1 terminal to terminal 3 on the relay.
Remove Power Wire from the GRIDlink IPm
Remove the existing power supply wire from positive terminal 24 or 17 (depending how originally wired).
Reconnect power supply wire to relay terminal 2
Power Wire to the GRIDlink IPm
Connect a new power wire from relay terminal 1 to GRIDlink terminal 24 or optionally 17.
Be sure there is no other power source wired to either terminal 24 or 17.

This will be the default setting after the router is rebooted which will power the GRIDlink.

Wait a few minutes until the GRIDlink is confirmed OFF then return to default HIGH.
Final Test and Validation Prior to Deployment
-
- Observe the GRIDlink IPm LEDs and ensure the device powers up correctly after cycling.
- Confirm the remote I/O control operates as intended without manual intervention.
- Test various scenarios (e.g., scheduled cycling or manual toggling) to ensure reliability.
- Always double-check all connections for proper polarity and secure termination.
