Installing The System Into A Panel; Mounting Considerations - Xycom 9450 Manual

Installing the System into a Panel

The 9450's rugged design allow it to be installed in most industrial environments. The
9450 is generally placed in a NEMA 4/12 enclosure to protect against contaminants such
as dust, moisture, etc. Metal enclosures also help minimize the effects of electromagnetic
radiation that may be generated by nearby equipment. The remainder of this chapter
contains guidelines for installing the 9450.

Mounting Considerations

Once you have found a location for the 9450, install it in the enclosure according to the
manufacturer's instructions. Consider the following points and precautions before plac-
ing the 9450 inside an enclosure:
•
Select an enclosure that allows access to the 9450 ports and slide-out computer mod-
ule.
•
Account for the unit's depth as well as cabling when choosing the depth of the en-
closure.
•
Mount the 9450 in an upright position.
•
Place the 9450 at a comfortable working level.
•
Consider the location of accessories such as AC power outlets and lighting (interior
lighting and windows) for installation and maintenance convenience.
•
Prevent condensation by installing a thermostat-controlled heater or air conditioner.
•
Avoid obstructing air flow to allow for maximum cooling.
•
Place fans or blowers close to the heat-generating devices. If using a fan, make sure
that outside air is not brought inside the enclosure unless a fabric or other reliable
filter is also used. This filtration prevents conductive particles or other harmful con-
taminants from entering the enclosure.
•
Do not select a location near equipment that generates excessive electromagnetic in-
terference (EMI) or radio frequency interface (RFI) (equipment such as high power
welding machines, induction heating equipment, and large motor starters).
•
Place incoming power lines (such as isolation or constant voltage transformers, local
power disconnects, and surge suppressors) away from the 9450. The proper location
of incoming line devices keeps power wire runs as short as possible, and minimizes
electrical noise transmitted to the 9450.
•
Make sure the location does not exceed the 9450's temperature specifications. Refer
to Appendix A for these specifications.
•
Avoid overloading the supply circuit.
•
Incorporate a readily accessible disconnect device in the fixed wiring for perma-
nently connected systems.
•
Do not install in a rack in such a way that a hazardous condition occurs due to un-
even mechanical loading.
