• Limitations of the maximum ambient temperature at the electronics
enclosure may be required dependent on device configuration,
process temperatures and temperature classification.
• Details of limitations: →  12, "Temperature tables".
• To avoid electrostatic charging: Do not rub surfaces with a dry cloth.
• In the event of additional or alternative special varnishing on the
enclosure or other metal parts or for adhesive plates:
• Observe the danger of electrostatic charging and discharge.
• Do not install in the vicinity of processes (≤ 0.5 m) generating
strong electrostatic charges.
• Avoid sparks caused by impact and friction.
Optional specification, ID Px, Rx = PA
Connect the weather protection cover to the local potential
equalization.
Optional specification, ID Px, Rx = PB
Avoid electrostatic charging of the weather protection cover (e.g.
friction, cleaning, maintenance, strong medium flow).
