Location requirements
To avoid premature aging of the controller; ensure user security; and facilitate access, upgrades, and
maintenance, the following guidelines must be followed:
•
Install the controller:
–
On a standard 48.26 cm (19 in.) equipment rack
–
On a flat surface (such as a desk or a table)
•
Install the controller in a well-ventilated location where it will not be exposed to high temperatures or
humidity.
–
Storage temperature: -20 °C to +70 °C
–
Operating temperature: 0 °C to +40 °C
–
Humidity lower than 85% and non-condensing
•
Do not install the controller in a location exposed to direct sunlight or near stoves or radiators. Exces -
sive heat could damage the internal components.
•
Controller should be positioned to be accessible for future upgrade, maintenance and troubleshooting
and where cables can be easily connected.
•
Maintain a minimum of 25 mm (1 in.) clearance in front, in the back, on top, under, and on the sides of
the controller.
•
Keep airflow around and through the vents of the controller clear of any obstruction.
•
Do not put books or paper on the controller.
Wiring Guidelines
These guidelines apply for any cable, supplied or not, used with an EX controller.
•
Always use straight through cables.
•
Cables must not pull or create a lateral stress on the connectors; that is, they must be long enough.
•
Cables must be installed in such a way not to present a trip hazard to personnel working in the vicinity
of the equipment.

Keep cables away from:
–
Sources of electrical noise such as radios, transmitters, and broadband amplifiers
