Safety Information
1.1.4 Electrical Connection
When working on live drive controllers, applicable national regulations for the prevention of accidents (e.g.
VBG 4) must be observed.
The electrical installation must be carried out in accordance with the appropriate regulations (e.g.
cable cross-sections, fuses, PE connection). Additional information can be obtained from the regulatory
documentation.
The regulatory documentation contains information about installation in compliance with EMC (shielding,
grounding, filters and cables). These notes must also be observed for CE-marked controllers.
The manufacturer of the system or machine is responsible for compliance with the required limit values
demanded by EMC legislation.
1.1.5 Operation
Systems including controllers must be equipped with additional monitoring and protection devices according
to the corresponding standards (e.g. technical equipment, regulations for prevention of accidents, etc.).
You are allowed to adapt the controller to your application as described in the documentation.
DANGER!
• After the controller has been disconnected from the supply voltage, do not touch the live
components and power connection until the capacitors have discharged. Please observe the
corresponding notes on the controller.
• Do not continuously cycle input power to the controller more than once every three minutes.
• Close all protective covers and doors during operation.
WARNING!
Network control permits automatic starting and stopping of the inverter drive. The system design
must incorporate adequate protection to prevent personnel from accessing moving equipment
while power is applied to the drive system.
