Warning
:
Connect the power supply to the switch first, and then connect the power supply to power. Otherwise,
catastrophic product failure may occur.

adhesive tape over the circuit breaker handle to prevent accidental power restoration while you are working on
the circuit.
2. Insert the negative/positive DC wires into the V-/V+ DC Power Input terminals, respectively.
3. Use a small flat-blade screwdriver to tighten the wire-clamp screws on the front of the terminal block
connector.
4. Connect the power supply to power.
5. Check the SYS LED. If it is ON, the power connection is correct.
