Chapter 4 Removal and Replacement Procedures
Installing the Remote Power Cycling Feature Control Wires (Optional)
To install the ferrite bead on the remote power-cycling control wires, follow these steps:
Step 1
Remove the ferrite bead and the two plastic ties from the plastic bag.
Step 2
Open the ferrite bead as shown in
Figure 4-23
, View A.
Step 3
Place the two remote power-cycling control wires (18 AWG maximum) in the ferrite bead as shown in
Figure 4-23
, View B. Close the ferrite bead making sure that the two halves have completely snapped
together and are secure.
Step 4
Locate a point on the remote power-cycling control wires that leaves approximately 1 to 2 inches (2.5 to
5 cm) of exposed wire from the remote power cycling terminal block located on the front of the power
supply. Wrap one of the 4-inch plastic ties around the remote power-cycling control wires at that point.
Tighten the plastic tie so that it is snug against the control wires and cannot slide. See
Figure 4-23
,
View C.
Step 5
Slide the ferrite bead so that it is positioned just behind the first plastic tie wrap. Take the second plastic
tie and wrap it around the control wires directly behind the ferrite bead and tighten it so that the ferrite
bead cannot slide up or down the control wires. See
Figure 4-23
, View C.
Step 6
To finish the procedure, trim the excess plastic strap from the two plastic tie wraps.
