5. Operating Instructions
The AFITSEP AF460-30-11 AC Contactor operates by energizing its coil to close the main contacts, allowing power to flow to the connected load.
- Power On: Apply control voltage to the coil terminals (A1, A2). The contactor will energize, and the main contacts will close.
- Power Off: Remove control voltage from the coil terminals. The contactor will de-energize, and the main contacts will open, interrupting power to the load.
- Indicator: Observe any status indicators (if present) to confirm the contactor's state (e.g., ON/OFF).
