Wiring Guidelines & Enclosure Installation

• Line & Load Connections: Connect 3-phase AC main power to top line terminals and motor leads to bottom load terminals, verifying phase rotation before applying line power.
• Enclosure Mounting: Mount the open-type unit inside a properly ventilated NEMA/IP rated cabinet to prevent environmental contamination and ensure convection cooling.
• Control Power Termination: Supply regulated 100...240V AC control voltage to designated control terminals, keeping signal wire separate from high-power line cables.

Frequently Asked Questions
