!!! DANGER !!!
Verify power is disconnected by removing a fuse or opening a circuit breaker before making
any connections or injury or death can result.
1. Disconnect power.
2. Mount
ICM492
securely against the metal chaises of the system in a water proof environment.
3. If a contactor or a relay is used in the system (see Fig.1) to control power to the load then:
a. Make L1 and L2 connections.
b. Cut the wire that powers the contactor/relay coil, strip and place 1/4” female spade terminals on them.
c. Plug female spade terminals on COM and N.O. terminals of
ICM492
.
4. Should you choose to drive the load directly (see Fig.2) using relay contacts of
ICM492
then:
a. Make sure that load current rating does not exceed current rating of
ICM492
relay contacts.
b. Cut the line that powers the load, strip and place 1/4” female spade terminals on them.
c. Plug female spade terminals on COM and N.O. terminals of
ICM492
.
5. Should you choose to use a control signal at Control Voltage input terminals then:
a. Use two wires with 1/4”female spade terminals on them to plug on Control Voltage terminals of
ICM492
.
b. Tap into control signal with the other end of the wires.
6. Press SELECT button to enter the select menu.
a. Use Up and Down arrows to adjust feature settings.
b. Make sure that the Control Mode is ON if the control signal is used at Control Voltage terminals.
