The 9112 is designed to be mounted to a panel within an enclosure. Care must be taken to prevent metal chips or
other conductive particles such as wire clippings from entering the unit during installation. Failure to protect the
unit may cause damage when power is applied and may void the warranty.
A minimum clearance of six inches should be kept between the 9112 and any other device that generates heat. In
the event that the internal enclosure temperature periodically exceeds 60°C (122°F), fans or a purge air system
must be used.
Communication Port Connectors
Both communication Port 1 and Port 2 are electrically and mechanically identical. The following electrical
schematic defines the connector pin assignments.
Notice: Undefined pins must remain disconnected.

The schematic below shows the cable required to transfer Configuration Files and Project Files between the 9112
and a personal computer. The cable is available from Quartech in a standard ten foot length. Cables up to fifty feet
in length are available.
