Environmental Specifications
The controller operates in an ambient temperature range of 0°C (32°F) to
50
°C (122°F). The unit can tolerate atmospheric pollution degree 2: only dry,
non-conductive pollution is acceptable. Therefore, we recommend that you
mount the controller in a suitable enclosure as described in “Installation
Safety Requirements” on page 63.

Cooling
The environment in which you operate the controller must meet the cooling
requirements listed below and shown in Table 4.
• For proper cooling, install the controller vertically. (Chapter 3 provides
installation guidelines, starting on page 63.)
• Avoid installing heat-producing equipment directly below the controller.
• Make sure the ambient air temperature entering the controller, or rising
up to the controller, is within acceptable ambient temperature limits.
Under normal use, the temperature of air leaving the controller may be
25
°C (45°F) above ambient temperature.
• After installation, verify that the ambient air temperature directly below
the top-most controller does not exceed the Still Air maximum (see
“Operating Temperature” above). In addition, make sure that nothing
obstructs the circulating airflow.
