Installation Chapter 2
Installation Site
Consider the following when selecting the installation site:
A. The operating ambient temperature should be between 0…40 °C
(32…104 °F) for NEMA Type 1 or 12 and arc resistant enclosures. For
higher ambient conditions, please consult Rockwell Automation factory.
B. The relative humidity must not exceed 95%, non-condensing. Excessive
humidity can cause electrical problems from corrosion or excessive dirt
buildup.
C. The equipment must be kept clean. Dust buildup inside the enclosure
inhibits proper cooling and decreases the system reliability. The
equipment should not be located where liquid or solid contaminants can
drop onto it. Controllers with ventilated enclosures must be in a room free
of airborne contaminants.
D. Only persons familiar with the function of the controller should have
access to it.
E. The losses in the controller produce a definite heat dissipation, depending
on the unit size, that tends to warm the air in the room. Attention must be
given to the room ventilation and cooling requirements to ensure that the
proper environmental conditions are met.
F. Operational altitude is 1 km (3300 ft) maximum without derating. Higher
altitudes may require optional components. Please consult Rockwell
Automation factory.
G. The area of the controller should be free of radio frequency interference
such as encountered with some welding units. This may cause erroneous
fault conditions and shut down the system.
ATTENTION: Care must be exercised when using either a forklift, or the pipe
rolling technique, for positioning purposes to ensure that the equipment is not
scratched, dented or damaged in any manner. Always exercise care to stabilize
the controller during handling to guard against tipping and injury to personnel.
ATTENTION: An incorrectly applied or installed controller can result in
component damage or a reduction in product life. Wiring or application errors,
such as, undersizing the motor, incorrect or inadequate AC supply, or ambient
temperatures above or below the specified temperature range may result in
malfunction of the controller.
