– connect inverter directly to battery terminals. Therefore, you typically wire your contactor through the

For a phase loss relay, the . Therefore, you typically wire your contactor through the N/C (terminal 12) so that when power fails, the contactor drops out. Wiring through N/O (terminal 14) would keep the motor running even during a fault.

Before diving into the wiring diagram, it is essential to understand what the Qp3-12a actually is. The "Qp3" typically designates a series of protective relays or switching devices, often manufactured by European automation brands (such as Broyce Control, Lovato, or similar OEMs). The "12a" suffix generally indicates the device's amperage rating—specifically, a 12-amp switching capacity for its output relay contacts.

If your device is not working, follow this logical flow:
