Checklist (5) - Cooling system checks
Check
OK
Natural cooling
Have you adjusted the torque or the power of the motor at the converter based on the
table in Chapter "Derating factors (Page 27)"?
Follow the Operating Instructions of the converter.
Forced ventilation
Have you checked all safety-related and functionally relevant details?
Examples:
•
Have you compared the data of the external cooling unit with the connection data?
Connect the external cooling unit only if the supply data does not result in an over-
load condition.
•
Has the forced ventilation unit, including accessories, been correctly installed, e.g.
fitting of the protective conductor?
•
Are the mechanical installation and electrical installation of the safety-related com-
ponents correct? This includes the installation of the motor circuit-breaker and the
fitting of protective grilles, for example.
•
Are the cable entry glands correctly fitted and tight?
•
Are the fan air intake and the area around the fan blades free of foreign bodies?
•
Is the fan rotation direction correct?
An arrow is stamped on the fan rating plate. This arrow indicates the correct direc-
tion of rotation of the fan. An arrow is also marked on the fan blades. When the fan
starts, you can check the direction of rotation using the arrows. The fan is function-
ing correctly if the direction of rotation of the blades matches the direction of the
arrow on the fan rating plate.
Can the motor only be switched on when the fan is running?
