General installation instructions
If the enclosure is made of non-metallic materials, or if it is made of metal having a
paint layer thicker than 0,2 mm (group IIC), or 2 mm (group IIB, IIA, I), or any thickness
(group III), electrostatic charges shall be avoided.
For an ambient temperature ≥ 60ºC, heat resistant cables shall be used with a rating of
at least 20 K above the ambient temperature.
The enclosure shall be suitable for the application and correctly installed
The distance between terminals, inclusive the wires bare part, shall be at least 3 mm
separated from any earthed metal.
'TEST' connection, may only be applied when the area is safe, or if supply / output
circuit and the applied current meter are intrinsically safe.
