Tripp Lite SR18UB Enclosure Configuration, Door Locks, Reversing the Doors, Mounting Rails

5.Enclosure Configuration

5.1Door Locks

The front and back doors have locks that are accessible by the included keys.

Each side panel locks using an L-shaped lever on the inside of the enclosure.

1To unlock and remove the side panels, lift the shorter leg of the “L” up and pull it away from the side panel. Pull the tab on the side panel and remove it from the enclosure.

2To re-lock the side panels, secure it in the proper position, lift the shorter leg of the “L” up and push it toward the side panel, back into the hole that it was in initially. Once it is in place, push the shorter leg of the “L” down to lock it. Note: To lock and unlock the side panels, you will need to have access to the interior of the enclosure.

5.2 Reversing the Doors

The doors of the enclosure are held in position on the enclosure’s frame with two spring-loaded pins. To reverse the door’s swing direction, simply release the pins by pulling them up (lower pin) or down (upper pin) and remove them from the mounting holes on the frame of the enclosure.

Flip the door in the opposite direction and replace the pins in the identical mounting holes on the other side of the enclosure’s frame by lining them up with the mounting holes and engaging them again.

5.3 Mounting Rails

The enclosure comes with mounting rails that have square holes for mounting rack equipment. To install equipment, use the included cage nuts and other hardware. (See page 7 for installation of cage nuts.) Warning: Be sure to have the enclosure in its final position on the floor before mounting any equipment inside. Also be sure to have all the right adjustments on your rails before mounting equipment. (See below for Adjusting Mounting Rail Depth.)

5.4 Adjusting Mounting Rail Depth

Warning: Do not attempt to adjust rails while equipment is installed in the enclosure.

Do not attempt to use rails without screws installed. (2 per rail.)

The 4 mounting rails are pre-installed to accommodate equipment with a mounting depth of 20.5 inches (521 mm). Do not adjust the mounting rails unless your equipment requires a different mounting depth. The front and rear sets of rails can be adjusted independently for mounting of equipment with depths between 3 inches (76 mm) and 32.5 inches (826 mm).

Each rail is connected to the enclosure with 2 screws and 2 cage nuts: 1 set in the upper	2
corner and another in the lower corner. Using a Phillips-head screwdriver, remove the screws	1
that fasten the rails to the enclosure.

Move cage nuts to desired depth and reinstall.

Slide the mounting rails to the desired depth and reattach them using the screws you removed in Step 1.
