Touch up any damaged paintwork

If the paint is damaged, it must be repaired in order to protect the unit against corrosion.
CAUTION
Paint system
Contact the Service Center before you repair any paint damage. They will provide you with
more information about the correct paint system and methods of repairing paint damage.
Repainting explosion-proof motors
The paint coat can become electrostatically charged where there is a thick coat. Electrostatic
discharges can occur. There is a risk of explosion if potentially explosive mixtures are also
present at this moment. This can result in death, serious injury or material damage.
You must comply with one of the following requirements when you repaint painted surfaces:
● Limit the surface resistance of the paint used:
● Breakdown voltage ≤ 4 kV for explosion group III
Suitability test of the paint system for hazardous areas
Proof is available for the electrostatic suitability with explosion-proof machines for the paint
systems ordered by default. For paint systems specifically requested by customers such
evidence is not available. Take this into account when repainting.

WARNING
Surface resistance ≤ 1 GΩ for motors of explosion group III
