power cord.
To connect the DC power cord:
1.
Remove the plastic cover over the wiring terminals, and use a Phillips screwdriver to remove
the M5 screws.
The recommended torque is 20 kgf-cm (1.96 Nm).
2.
Connect the wire marked with the negative polarity symbol (

the power supply. Connect the wire marked with the positive polarity symbol (

3.
Fasten the M5 screws to secure the wires and then install the plastic cover.
4.
Connect the other end of the power cord to a DC power source.
5.
Examine the input status LED (IN OK) on the power supply. If the LED is green, the power
cord is successfully connected. If the LED is off, examine the installation, troubleshoot the
problems, and try again until the LED is on.
