Note
• Condensation drain holes are only used in motors with degree of protection IP 55.
For motors with degree of protection IP 23 (open-circuit ventilation), the open design does
not require condensation drain holes. It is not possible that a potentially damaging amount
of condensation can collect.
• Anti-condensation heating (see Chapter "Anti-condensation heating") can be used to
supplement condensation drain holes.
