Emerson MONITORING OpenComms Manuel D’Utilisation

The OpenComms NIC card 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-

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.
