Connecting the DC power cord for the fixed DC power
module (method 2)
To avoid connection mistakes, i
dentify the positive (+) and negative (-) marks
above the DC power
receptacle before connecting the switch to a –48 VDC power source.
No DC power cord is provided with the switch. As a best practice, purchase a DC power cord with a
current carrying capacity over 6A.
To connect the DC power cord for the fixed DC power module:
1. Correctly orient the terminal block and attach the terminal block to the power receptacle on the
power module, as shown by callout 1 in Figure 26.
If you orient the terminal block upside down, you cannot attach it to the power receptacle.
2. Use a flat-head screwdriver to fasten the screws on the terminal block to secure the terminal
block to the power receptacle. See callout 2 in Figure 26.
3. Insert the two DC power wires into the terminal block, as shown by callout 1 in Figure 27.
4. Use a flat-head screwdriver to fasten the screw at the top of the terminal block to secure the DC
power cord to the power receptacle. See callout 2 in Figure 27.
5. Connect the other end of the power cord to a –48 VDC power source.
