SITELINK-E
Product Specification/Installation Sheet
Description
The Liebert SiteLink-E is a product
platform that comes in three models:
SiteLink-12E, -4E and -2E. The models
differ only in the number of Emerson
family ports at the bottom of the module.
SiteLink-E supports Emerson interfaces
as a BACnet router that provides the
communications link between Liebert
units and other protocols and modules.
The SiteLink-E is designed to
communicate with Liebert equipment—
environmental units, UPSs and Power
Distribution Units—and route the
information over a BACnet, Modbus or
LONWorks™ network to a Building
Automation System (BAS) workstation.
