General installation instructions
If the enclosure is made of non-metallic materials or of painted metal, electrostatic
charging 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 maximum surface temperature of the outer enclosure is 20 K hotter than the
maximum ambient temperature.
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.
