Preconditions for adequate cooling
● For 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 should not be drawn in again.
NOTICE
Overheating
If the required cooling air flow cannot be maintained, the machine can overheat. This can
result in material damage.
● Maintain the required minimum clearance for customer-supplied mounted accessories
at the air intake opening and at the air discharge openings to ensure the required
cooling air flow.
● Comply with the conditions of the IP degree of protection.
More stringent requirements regarding the IP degree of protection may necessitate the
installation of suitable filters and special arrangement of the intake and outlet openings.
● Equipment and cables must be connected without strain.
