3.1 Section Safety

3.1 Section Safety
Do not connect or disconnect wiring while the power is on.
Failure to comply will result in death or serious injury.
Do not operate equipment with covers removed.
Failure to comply could result in death or serious injury.
The diagrams in this section may show drives without covers or safety shields to show details. Be sure to reinstall
covers or shields before operating the drives and run the drives according to the instructions described in this manual.
Make sure the protective earthing conductor complies with technical standards and local safety regulations.
When an EMC filter is installed or with models CIMR-A4A0414 and larger, the leakage current exceeds 3.5 mA.
Therefore according to IEC/EN 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 10
2 2
mm (Cu) or 16 mm (Al) must be used.
Use appropriate equipment for residual current monitoring/detection (RCM/RCD).
This 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/EN 60755.
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.
Do not remove covers or touch circuit boards while the power is on.
Failure to comply could result in death or serious injury.
Do not allow unqualified personnel to perform work on the drive.
Failure to comply could result in death or serious injury.
Installation, maintenance, inspection, and servicing must be performed only by authorized personnel familiar with
installation, adjustment, and maintenance of AC drives.
Do not touch any terminals before the capacitors have fully discharged.
Failure to comply could result in death or serious injury.
Before wiring terminals, disconnect all power to the equipment. The internal capacitor remains charged even after the
power supply is turned off. After shutting off the power, wait for at least the amount of time specified on the drive
before touching any components.
