INSTALLATION GUIDELINES
30
These instructions for the installation and maintenance do not contain all particulars which might
arise during the installation and application of the cage motor. We therefore insist on its being
mounted and maintained by qualified persons (IEC 364).
1. TRANSPORT AND STORAGE
THE MOTORS ARE TO BE STORED IN A CLOSED AND DRY AREA. Should they be stored
outdoors, it is important to protect them against bad weather conditions. During transport make
sure that the usual precautions for this kind of material are respected. 4KT(B)CD motors are to be
handled with lifting-claw.
