terminal. Connect the 2 switch circuits to the S1 and S2 input terminals and the

negative wire. Connect the load circuit to the O terminal and the Neutral wire.

Connect the I terminal to the circuit breaker. If you are using 12 V DC to power the

Device and want to switch a DC load circuit (ﬁg. 4), connect the Device power supply

positive wire to the +12 terminal and the Device power supply negative wire to the L

terminal. Connect the 2 switch circuits to the S1 and S2 input terminals and the

Device power supply negative wire. Connect the load circuit to the O terminal and

one of the load circuit power supply wires. Connect the I terminal to the other load

circuit power supply wire.

⚠CAUTION! The load circuit voltage should not exceed 30 V DC and the current

should not exceed 12 A.

⚠ RECOMMENDATION For inductive loads, which cause voltage spikes during

switching, such as electrical motors, fans, vacuum cleaners, refrigerators and similar

ones, RC snubber (0.1µF / 100Ω / 1/2W / 600V AC) should be wired in parallel with the

load. RC snubbers can be purchased at
