Manufacturer said L2 and L3 can be shorted to L1 for use in single phase.
A1 a2 contactor connection. VPR voltage protection relay used is 3 phase type. L1 L2 and L3 are the incoming terminals of the main contact which are to be connected. The A1 wire terminal is where the 24-volt DC positive signal wire gets connected.
A1 and A2 are magnetic coil terminals. This is where we can connect a 24-volt DC power to the coil to energize it. Im not sure how to connect the relay output terminals NO NC COM etc to contactor control terminals A1 and A2 in the wiring diagram below.

Pool Pump Motor Wiring. T1 has a wire connected. A1A2 Control coil voltage across these 2 activates contactor L1L2 Line side power in T1T2 Load side.
If there is a freewheeling diode over the coil then the polarity of the DC voltage on A1 and A2 must match the freewheeling diode. If A1 and A2 are the coil connections on the contactor connecting an ac supply will energise it and the magnetic hysteresis will ensure that it remains energised when the supply changes direction alternates. In deactivated state there is no current on any connection of contactor A.
Suggest looking up the diagram for the specific manufacturerpart but from a Google this looks like the common scheme. Fundamentally it doesnt matter which way round you connect. Ad Tickets On Sale Today Secure Your Seats Now International Tickets 2021.
