Environmental safety This controller has not been designed to withstand explosions,
dust-proof, nor is it splash-proof. Therefore, it should not be
installed in any environment where:
(1) there are flammable gases or liquids,
(2) there are any shavings from metal processing or other
conductive material flying about,
(3) there are any acidic, alkaline or other corrosive material,
(4) there is a mist, or
(5) there are any large-sized inverters, high output/high
frequency transmitters, large contactors, welders, or other
sources of electrical noise.
Work space Adequate space should be allowed around the controller for
inspection, overhaul and maintenance work.
Grounding resistance The grounding resistance of the power supply should not be
more than 100.
