Mounting in CAB-3/CAB-4 Series Cabinets
This section contains instructions for the installation of the Auxiliary
Power Supply into a CAB-3/CAB-4 Series cabinet.
These cabinets use a CHS-4 Series chassis to mount the APS-6R.
Instructions for mounting:
Chassis Mounting
The illustration below shows an APS-6R being mounted in a CHS-4L
chassis. Mounting in any CHS-4 Series chassis is accomplished in the
same way.

Step
Action
1
Remove plastic cover from APS-6R.
2
If 240 VAC is to be used, cut JP1 jumper at this time. See instructions and
high voltage warning on Page 18 in "Configuring the APS-6R".
3
Place the APS-6R onto the mounting studs of the chassis (Figure 4 on page 12).
4
Insert a standoff through each of the printed circuit board mounting holes,
threading each standoff to the mounting studs on the chassis. Use #6-32
hex standoffs, 1.25 in. (32 mm) long.
5
Tighten the standoffs until the APS-6R is securely fastened to the chassis.
6
Reinstall the plastic chassis cover.
