•
Place any fans or blowers close to the heat generating devices. If using a fan,
make sure that outside air is not brought into the enclosure unless a fabric or
other reliable filter is used. This filtration prevents conductive particles and other
harmful contaminants from entering the enclosure.
•
Do not select a location near equipment that generates excessive electromagnetic
interference (EMI) or radio frequency interface (RFI). Examples of these types of
equipment are: high power welding machines; induction heating equipment; and
large motor starters.
•
Place incoming power line devices (such as isolation or constant voltage
transformers, local power disconnects, and surge suppressers) away from the
system. The proper location of incoming line devices keeps power wire runs as
short as possible and minimizes electrical noise transmitted to the unit.
•
Make sure the location does not exceed the unit’s shock, vibration, and
temperature specifications
•
Install the unit in the rack or panel in such a way as to ensure that it does not
cause a hazard from uneven mechanical loading
•
Incorporate a readily-accessible disconnect device in the fixed wiring on
permanently connected equipment
•
Avoid circuit overloading of the supply circuit
