CAUTION:
When connecting the power cord, make sure the circuit breaker is completely turned off for both the
positive and negative lines.
To connect the DC power cord:

protection cover. There are two flat washers, one spring washer, and one M6 fastening nut from
inside to outside on each wiring terminal.
2. Loosen the captive nuts on four wiring terminals with a M6 socket wrench, and remove the captive
nut, spring washer, and one flat washer in turn from each wiring terminal.
3. Connect the end of the blue DC power cord marked with – to the negative terminal (–) on the
power supply.
4. Connect the end of the black DC power cord marked with + to the positive terminal (+) on the
power supply.
5. Put the flat washer and spring washer on the wiring terminal in turn and screw up the captive nut
with the M6 socket wrench. Repeat this step for the other three terminals.
6. Put the protection cover on the wiring terminals and faster the captive screws.
7. Connect the other ends of the DC power cords to the wiring terminals that provide a power supply
to the switch.
