Step 3 - Check position of mounting brackets
APSs are pre-assembled with 19-inch rack-mounting brackets as shown in the

reduce the effective depth of the unit.
Rack-mounting brackets are also available for use in 23-inch wide racks.

Remove top cover if fitted.
2
Undo the two screws holding each bracket.
3
Refit the brackets at the required location. Tighten the screws.
