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 3-12
or
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.
