Rexroth IndraDyn A Application Notes 9-7
Notes:
• A side: The degree of protection on the flange side of
motors with a shaft seal is IP 65. However, the seal is
ensured only in case of splashing water. Liquid levels
present on the shaft end require a higher degree of
protection.
• B side: The degree of protection for the blower screens in
axial blowers is IP 24. Chips or larger dirt particles can
penetrate the blower screen as well.
• Protection class: The factory-attached protection class of
IndraDyn A motors must not be reduced by modifications
or by retrofitting accessories.
⇒ Already take the installation position and the protection class of the
motors into account when planning the system.
