quick install

1. Disconnect power sources prior to installation.

2. Remove the sensor lid and wire the command relay connections and relay controls to the base.

3. Set the relay contact jumper.

4. This device has four wiring options, detailed on page 2-3 of this installation guide. Choose the option appropriate to the application and follow instructions.

operation

The H540NS and H548NS devices combine a switching relay and a current status sensor into a single housing. The device is connected in series between the power source and the motor device, and the relay controls the on/o functioning of the motor. The current switch trip point is xed at 0.25 A on the H540NS and adjustable from 0.5 to 15 A in the H548NS. The maximum load is 15 A for both devices. The H540NS and H548NS require no additional power source for operation.
