CAUTION:
To avoid connection mistakes, identify the positive (+) and negative (-) marks above the DC power
receptacle before connecting the switch to a –48 VDC power source.
IMPORTANT:
No DC power cord is provided with the switch. Make sure the current carrying capacity of the DC

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 Figure2-26.
3.
Insert the two DC power wires into the terminal block, as shown by callout 1 in Figure2-27.
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 Figure2-27.
