NOTE
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference that the user alone must correct.

2.0 INSTALLING THE LIEBERT SITELINK-E MODULE

The Liebert SiteLink-E module comes in an enclosure for mounting on the wall or floor.

2.1 Preparations for Mounting the Module

2.1.1 Choose a Location to Install the Liebert SiteLink-E

The Liebert SiteLink-E module’s installation location must be easily accessible, within the allowable cable-run distances for communication wiring and have about 2 in. (51mm) on all sides for wiring and service.
• Refer to the following drawings in 2.2 - Enclosure Diagrams:
Figure 3 - Enclosure dimensions—overall Figure 4 - Enclosure dimensions—Wall mount Figure 5 - Enclosure dimensions—Floor mount
