Safety information
NOTICE
Motor destruction caused by incorrect connection
The direct connection to the three-phase line supply damages the motor.
•
Connect the motor only at the configured converters.
•
Observe the correct phase sequence.
6.2.2
High-voltage test
DANGER
Lethal voltage hazards
A dangerous voltage is present at the motor during a high-voltage test. Death or serious
injury can result when live parts are touched.
•
Do not touch any live parts.
•
Adhere to the fundamental safety instructions.
NOTICE
Destruction of electronic components and damage to the insulation
A high-voltage test on the motor can damage the insulation of the motor and destroy
electronic components, e.g. temperature sensors.
•
Use maximum 80% of the test voltage in accordance with EN 60034
-1.
•
Prior to the test, short-circuit the cable ends of the temperature sensors.
Before being shipped, the stators of the built-in motors are subject to a high-voltage test in
compliance with EN 60034-1.
However, the Standards Commission recommends that when electrical components (such
as built-in motors) are installed, a new high-voltage test according to EN 60034-1 should be
performed after the final assembly has been completed.
