Instructions relevant for safety
Caution
High temperatures can arise at the enclosure components of electric motors
(possibly > 100°C). Do not touch enclosure components while the motor is running
or immediately after it has been running.
Caution
When positioning temperature-sensitive components (wires etc.), make sure that
they are not in contact with the motor enclosure.
Notice
Also pay attention to the Technical Data on the rating plates on the motor
enclosure.
Cooling conditions in general
•= In the case of motors that are cooled by the ambient air, the cooling air must be
able to flow unimpeded to and from the motors. Hot discharged air must not be
reinducted (see also 2.5.1).
•= Ventilation openings may only be covered by louvered covers in motors of those
types of construction in which the openings point downwards.
Cooling conditions for motors with pipe connection
Motors that are configured to allow pipes to be connected and/or for operation with
a separately driven fan must have pipes and a fan of suitable type and
dimensioning mounted and connected to them.
