3. Wiring

LoadLoad power supply• Please ensure that a wire with sufficient capacity1

is securely connected.

2SA-320-Z• For input circuit wiring, use 0.5mm2 to 1.25mm2 oforwire, and avoid adjacent wiring to the load circuit.

SA-340-Z• To protect the circuit, circuit breaker or fuse should

4+3

be installed into the load power supply.
