Power wires: 24 ~ 12AWG(IEC 0.5~2.5mm2)
Install the power source wires with the plug properly. Screw the wire with plug securely. Then, plug in DC1 contacts.
If cascading the power to next device is needed, install the power wires and plug for another switch. Then, use DC2 contacts.
Note: Only up to four device units can be cascaded to receive power from one main power input source.
