Installing the Liebert SiteLink-E Module
2.0INSTALLING THE LIEBERT SITELINK-E MODULE
The Liebert SiteLink-E module comes in an enclosure for mounting on the wall or floor.
2.1Preparations for Mounting the Module
2.1.1Choose 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:
