1 Warning and safety information
General information
WARNING
These devices are at hazardous voltage levels and control rotating mechanical parts, which in some circumstances, can be
dangerous. Non-observance of the warnings or non-compliance with the instructions in this manual can lead to danger to
life, serious injury or substantial damage to property.
Only qualified personnel who have previously familiarized themselves with all the instructions regarding safety, installation,
operating and maintenance as set out in this manual are permitted to work on these devices. Successful and safe
operation of these devices depends on their proper mounting, operation and maintenance.
The line supply, direct current and motor terminals as well as the brake and thermistor cables are at hazardous voltage
levels even when the inverter is out of service. Once the power supply has been disconnected, wait at least 5 minutes until
the device has discharged itself. Only then can you start the installation work.
Since the fault current for this product can be greater than 3.5 mA AC, a fixed ground connection is required and the
minimum size of the protective conductor must comply with local safety regulations for equipment with a high leakage
current.
It is strictly prohibited for any mains disconnection to be performed on the motor-side of the system; any disconnection of
the mains must be performed on the mains-side of the inverter.
Before the inverter power supply is connected, it must be ensured that the motor terminal box is closed.
If an LED or similar indicator does not light up or is not active when a function is switched from ON to OFF, this does not
mean that the unit has been switched off or is current-free.
The inverter must always be properly grounded.
The device must be isolated from the power supply before any connections at the device are established or changed.
Make sure that the inverter has been configured for the correct supply voltage. The inverter must not be connected to a
higher supply voltage.
The general and regional installation and safety regulations for working on equipment at high hazardous voltage levels
(e.g. EN 50178) as well as the relevant stipulations regarding the correct use of tools and personal protective equipment
(PPE) are especially to be observed.
CAUTION
Children and other unauthorized persons must be forbidden from accessing the devices!
It is only permissible to use these devices for the purpose specified by the manufacturer. Unauthorized changes and the
use of spare parts and accessories which are not sold or recommended by the manufacturer of the device can lead to fires,
electric shock and injuries.
NOTICE
This manual is to be kept somewhere close to the devices and must be easily accessible for all users.
If measurements or tests have to be carried out on the live device, the stipulations of safety regulation BGV A2 are to be
complied with, especially § 8 "Permissible deviations during work on live parts". Suitable electronic tools are to be used.
Before mounting and commissioning, please read these safety instructions and the warnings carefully as well as the
warning labels on the devices. It must be ensured that the warning labels are always legible; any signs that are damaged
or missing are to be replaced.
Make sure that suitable circuit breakers/fuses (with the specified rated currents) are installed between the line supply and
the inverter.
The manual is intended for users who have experience in handling the following equipment:
- PLCs
- STARTER commissioning software
- PROFIdrive profile and protocols.
The commissioning instructions in this manual only apply to standard inverters. The fail-safe commissioning is described in
the operating instructions.
