EN 7
•
Do not allow unqualified personnel to use equipment.
Failure to comply could result in death or serious injury.
Maintenance, inspection, and replacement of parts must be performed only by authorized
personnel familiar with installation, adjustment, and maintenance of AC drives.
•
Do not remove covers or touch circuit boards while the power is on.
Failure to comply could result in death or serious injury.
•
Always ground the motor-side grounding terminal.
Improper equipment grounding could result in death or serious injury by contacting the motor
case.
•
Do not perform work on the drive while wearing loose clothing, jewelry or without eye protection.
Failure to comply could result in death or serious injury.
Remove all metal objects such as watches and rings, secure loose clothing, and wear eye
protection before beginning work on the drive.
•
Never short the output circuits of the drive.
Do not short the output circuits of the drive. Failure to comply could result in death or serious
injury.
•
Make sure the protective earthing conductor complies with technical standards and local safety
regulations.
When an EMC filter is installed, leakage current exceeds 3.5 mA. Therefore according to IEC
61800-5-1 automatic power supply interruption in case of discontinuity of the protective
earthing conductor must be provided or a protective earthing conductor with a cross section of at
least 10mm
2
(Cu) or 16mm
2
(Al) must be used.
•
Use appropriate equipment for residual current monitoring / detection (RCM / RCD).
The drive can cause a residual current with a DC component in the protective earthing
conductor. Where a residual current operated protective or monitoring device is used for
protection in case of direct or indirect contact, always use an RCM or RCD of type B according
to IEC 60755.
Sudden Movement Hazard
•
Stay clear of the motor during rotational Auto-Tuning. The motor may start operating suddenly.
During automatic starting of equipment, the machine may start moving suddenly, which could
result in death or serious injury.
•
System may start unexpectedly upon application of power, resulting in death or serious injury.
Clear all personnel from the drive, motor, and machine area before applying power. Secure
covers, couplings, shaft keys, and machine loads before applying power to the drive.
