Tests regarding the second characteristic numeral must be performed
using fresh water. If cleaning is effected using high pressure and/or
solvents, coolants, or penetrating oils, it might be necessary to select a
higher degree of protection.
The design of the MSM motors complies with the following degrees of
protection according to DIN VDE 0470, Part 1, ed. 11/1992 (EN 60 529):
