To connect power using a DC terminal block screw connector:
1. Remove the terminal block screw from the chassis power socket (labeled DC IN ), by
unscrewing the two screws located on the front of the terminal block.
2. Ensure that the power feed cables that you want to use are not connected to your DC
power outlet.
3. Create a DC power feed cable by inserting two 48 VDC insulated wires (up to 10
AWG) into the terminal block screw. Secure the wires by fastening the two screws,
each one located directly above each wire. Ensure the correct polarity (po /
negative -), as indicated under the
DC IN label.
4. Connect the two insulated wires to the correct DC power outlet. Ensure that the
connections to the DC power outlet maintain the correct polarity.
5. Re-insert the terminal block screw connector into the DC inlet located on the chassis.
Secure the terminal block by tightening the two screws located on the front of the
terminal block.
When power is received, the PWR IN LED is lit (green).
