Forced ventilation

When mounting the forced ventilated motor, make sure the motor is well ventilated. Good
ventilation is especially important for encapsulated installation. Avoid warm exhaust air being
drawn in again. The cooling air must flow in and out without restriction. Avoid accumulated dirt
in the cooling ducts as this can reduce the cooling air flow.
All catalog data refer to an ambient temperature of 40 °C and an installation altitude up to
1000 m above sea level.
NOTICE
Thermal damage to temperature-sensitive parts
The motors can have surface temperatures of over +100 °C. Temperature-sensitive parts in
contact with the motor or attached to the motor can be damaged. Temperature-sensitive parts
include cables and electronic components, for example.
• Never attach temperature-sensitive parts to the motor.
• Ensure that no temperature-sensitive parts are in contact with the motor.
