IMPORTANT: All wiring must be performed by a qualified electrician in accordance with all applicable electrical codes.
- Disconnect all power sources before beginning wiring.
- Open the enclosure cover.
- Route power and control wiring through designated conduit entries. Ensure proper strain relief and sealing to maintain the NEMA 4 rating.
- Connect the motor starter components (not included with enclosure) according to their specific wiring diagrams.
- The enclosure is designed for AC3 operation with a rated operational current (Ie) of 20A and an operational voltage (Ue) of 415V at 50Hz. The coil voltage is 430V.
- Ensure all connections are tight and secure.
- Close and secure the enclosure cover.
5. Operation
5.1. Starting the Motor
To start the motor, press the green 'I' button located on the front of the enclosure. This will energize the motor starter and initiate motor operation.
