Installation

2.0 INSTALLATION

The OpenComms NIC-485 may be ordered as a factory-installed

option, and it may be installed as a kit for field retrofit to existing Lie-

bert units or as a self-contained unit in its own enclosure.

If ordered as a factory-installed option, proceed to 2.3 - User Connec-

tions for OpenComms NIC-485.

2.1 Retrofit Kit

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.

2.2 Self-Contained 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.
