Connecting explosion-proof AC motors
Observe the following instructions when connecting explosion-proof AC motors to
MOVIDRIVE
®
drive inverters:
•
The inverter must be installed outside the potentially explosive area.
•
Observe industry-specific and country-specific regulations.
•
Observe the regulations and information of the motor manufacturer with regards to
operation on a frequency inverter, e.g. mandatory sine filter.
•
In future, all tools and fixtures in the potentially explosive atmosphere must comply
with directive 94/9/EC (ATEX 100a).
•
The TF/TH input on the MOVIDRIVE
®
unit must not be used for thermal monitoring
of the motor. Use a TF/TH trip switch for thermal monitoring that is approved for use
in potentially explosive atmospheres.
•
If the motor is equipped with speed feedback, the speed sensor must also be
approved for use in potentially explosive atmospheres. The tachometer can be
directly connected to MOVIDRIVE
