Protection
•
Ensure that primary protection exists for the input wiring to the equipment. This protection must be
able to interrupt the available fault current from the power line. The equipment may or may not be
equipped with an input disconnect (option).
•
All cable entry openings must be sealed to reduce the risk of entry by vermin and to allow for
maximum cooling efficiency.
•
Follow all warnings and precautions and do not exceed equipment ratings.
•
If using multiple motors provide separate overload protection for each motor and use V/f control.
•
External dynamic braking resistors, if supplied, must be thermally protected.
•
It is the responsibility of the person installing the ASD or the electrical maintenance personnel to
setup the Emergency Off braking system of the ASD. The function of the Emergency Off braking
function is to remove output power from the drive in the event of an emergency. A supplemental
braking system may also be engaged in the event of an emergency.
Note: A supplemental emergency stopping system should be used with the ASD.
Emergency stopping should not be a task of the ASD alone.
System Integration Precautions
The following precautions are provided as general guidelines for the setup of the ASD within the
system.
•
The Toshiba ASD is a general-purpose product. It is a system component only and the system
design should take this into consideration. Please contact Toshiba for application-specific
information and for training support.
•
The Toshiba ASD is part of a larger system and the safe operation of the device will depend on
observing certain precautions and performing proper system integration.
•
A detailed system analysis and job safety analysis should be performed by the systems designer
and/or systems integrator before the installation of the ASD component. Contact Toshiba for options
availability and for application-specific system integration information if required.
Personnel Protection
•
Installation, operation, and maintenance shall be performed by Qualified Personnel Only .
•
A thorough understanding of the ASD will be required before the installation, operation, or
maintenance of the ASD.
•
Rotating machinery and live conductors can be hazardous and shall not come into contact with
humans. Personnel should be protected from all rotating machinery and electrical hazards at all
times.
