Connections and Configuration

3.4RS422 SiteScan Web Connector

The Liqui-tect panel will interface with Liebert’s SiteScan Web enterprise monitoring system. SiteScan can be used to monitor the Liqui-tect panel from a host computer and silence the audible alarm. The terminal block connector, TB8, is on the bottom edge of the board, near the left corner.

To connect the SiteScan Web to the Liqui-tect panel:

1.Disconnect electrical power to the Liqui-tect panel.

2.If necessary, remove a conduit knockout to permit wire entry into the Liqui-tect panel enclosure.

3.Bring the wire(s) into the Liqui-tect panel enclosure through a conduit knockout or access slot.

4.Loosen the appropriate screw and slip the stripped end of the wire into the terminal block. Note that the wires are polarity sensitive.

5.Tighten the screw until it holds the wire snugly.
