Protection Class

The protection classes according to IEC 60529 apply for IndraDyn A
motors. It must be ensured that, in each and every installation position of
the motor, the motors are not subjected to ambient conditions outside of
the applicable degree of protection.
The degree of protection is defined by the abbreviation IP (International
Protection) and two reference numbers specifying the degree of
protection. The first code number describes the protection class against
contact and penetration of foreign substances; the second code number
describes the protection class against water penetration.
