Repair to intrinsically safe
Do not apply any permanent inductive or capacitance loads to
the circuit without ensuring that this will not exceed the
permissible voltage and current permitted for the equipment in
intrinsically safe components are the only types that can be
worked on while live in the presence of a flammable atmosphere.
The test apparatus shall be at the correct rating.
Replace components only with parts specified by the
manufacturer. Other parts
may result in the ignition of refrigerant in the atmosphere from a
Check that cabling will not be subject to wear, corrosion,
excessive pressure, vibration, sharp edges or any other adverse
environmental effects. The check shall also take into account the
effects of aging or continual vibration from sources such as
compressors or fans.
