Installing the support rails for the 2145 UPS-1U
You must install the support rails in the rack before installing the 2145 UPS-1U.
Complete the following prerequisites before installing the support rails:
1. Use the customer's hardware-location chart to determine where in the rack that the 2145 UPS-1U is to
be installed.
2.
At the back of the rack, observe the Electronic Industries Alliance (EIA) positions and determine
where you are going to install the 2145 UPS-1U. Because of its weight, position the 2145 UPS-1U
where it is easy to handle in one of the lower positions in the rack.
Perform the following steps to install the support rails for the 2145 UPS-1U:
1. Open the top of the 2145 UPS-1U shipping carton. Grip the flaps on either side of the 2145 UPS-1U.
2. Lift the 2145 UPS-1U clear of the shipping carton and place it on a flat, stable surface with the front
facing you.
3.
Attach the long side of a mounting bracket

rail size to the depth of your rack. After you adjust the depth, tighten the assembly wing nuts as
much as possible while still allowing some movement.
