Step 6 Connect the input power as described in the “Wiring the DC Input Power Source” section.

Wiring the DC Input Power Source

Step 1 Using a wire-stripping tool, strip each of the four wires from the DC-input power source to the appropriate length for the terminals.

Warning Use copper conductors only. Statement 1025

Step 2 Using a Panduit crimping tool, crimp the fork-type terminals to the copper conductor, 90C, 14-AWG DC power input wires.

Step 3 Connect the DC-input power terminals to the terminal blocks. See Figure 3-12or Figure 3-13. Make sure to match the polarity (negative to negative, positive to positive) when connecting the wires to the terminal blocks. Connect the ground wire to a grounded metal rack or to earth ground if the switch is not in a grounded rack.
