Pre-Installation Planning - Orientation of Rack Mounting

The HC900 Controller must be mounted in suitable equipment enclosures. That is, all components such as the Controller rack, IO Expander Racks, and the Operator Interface manufactured by Honeywell must be mounted in approved furniture designed for industrial applications.

Orientation of Rack Mounting

Racks must be mounted as indicated in illustrations throughout this manual, so as to provide for vertical airflow through the racks. That is, racks must never be mounted vertically, and must never be mounted with the backplane horizontal (for example, flat on a horizontal panel or tabletop). Environmental specifications apply only to the normal mounting configuration.

Heat Rise De-rating

The HC900 is rated to operate at 60o C. However, for maximum reliability, the following guidelines should be observed for applications above 52o C.

1.Locate lower-power modules (Analog Input , Contact Input, etc) beside the Controller Module, and keep higher-power modules (AC Output, AC Input, etc) away from the Controller Module. For power consumption of each module, refer to Table 7.

2.For 240 Vac applications and temperatures above 56o C, or 264Vac, 52o C , de-rate the number of ON inputs per AC input module. (See AC Input de-rating data, see Figure 18.)

3.Limit the number of Analog Output modules to a maximum of 10 per rack. . (See Figure 19.)
