Surface And Corrosion Protection - Lenze g500-B Manual

Surface and corrosion protection

Depending on the ambient conditions, the surface and corrosion protection system (called
OKS) offers tailor-made solutions for optimum protection.
Various surface coatings ensure that the motors operate reliably even at high air humidity, in
outdoor installation or in the presence of atmospheric impurities. Any color from the "RAL
Classic" collection can be chosen for the top coat.
The OKS-XL (extra Large) version requires a check by your responsible Lenze
subsidiary.
