screw the four decorative screws through the holes in the
ears of the UPS and into the screw clips.

on the sides of the bezel with the slots on the front of the
Step-Down Transformer and gently snap it into place.
Install the bezel with the rear fins

The Step-Down Transformer is packaged in a robust shipping carton. Carefully remove the package contents. The
packaging is recyclable; save it for reuse or dispose of it properly.
Inspect the equipment upon receipt. APC has designed robust packaging for your product. However, accidents
and damage may occur during shipment. Notify the carrier and dealer if there is damage or missing equipment.
Check the packaging contents. The shipping package contains the Step-Down Transformer, mounting rails, and
mounting hardware. Your package may contain a Bezel Kit. If the bezel is not already installed, snap it on to the
UPS as instructed below.
This section provides information on the steps required to install and connect the Step-Down Transformer.
Follow the instructions contained in the Addendum SU Rack-Mount Rails 2U-5U sheet (990-7034G) to mount
the rails in your NetShelter or 19 in (46.5 cm) rack.
*It is recommended that the Step-Down Transformer is installed directly above the UPS in the rack.
