8 Installation

Section 2: INSTALLATION

The OpenComms NIC card may be ordered as a factory installed

option, or in a kit for field retrofit to existing Liebert units or as a

self-contained unit in its own enclosure.

If ordered as a factory-installed option, proceed directly to

subsection on User Connections.

As a retrofit kit, the circuit board is secured to a metal mounting

plate. The mounting plate then is attached to a flat metal surface

in a low-voltage section of the Liebert unit.

The self-contained model packages the interface card inside a

steel enclosure, for mounting external to the Liebert unit. A low-

voltage transformer is also provided.

RETROFIT INSTALLATION

Position the OpenComms card in the low voltage/control cavity

of the Liebert Deluxe System/3 unit. Refer to Figures 2, 3 and 4

for typical positioning. Use three #8 x ½” sheet metal screws to

affix mounting plate to the Environmental unit.
