1. General
Do not use defective devices or devices with defective or damaged housings or missing covers (e.g.
blind plugs for cable glands). Otherwise there is a risk of serious or fatal injuries caused by electric
shock or bursting electrical components such as powerful electrolytic capacitors.
Unauthorised removal of covers, improper use, incorrect installation or operation causes a risk of
serious personal injury or material damage.
During operation and depending on the protection class of the devices, there may be live, bare,
moving or rotating parts or hot surfaces.
The device operates with a dangerous voltage. Dangerous voltage may be present at the supply lines,
contact strips and PCBs of all connecting terminals (e.g. mains input, motor connection), even if the
device is not working or the motor is not rotating (e.g. caused by electronic disabling, jamming of the
drive or a short circuit at the output terminals).
The device is not equipped with a mains switch and is therefore always live when connected to the
power supply. Voltages may therefore be connected to a connected motor at standstill.
Even if the drive unit has been disconnected from the mains, a connected motor may rotate and
possibly generate a dangerous voltage.
If you come into contact with dangerous voltage such as this, there is a risk of an electric shock, which
can lead to serious or fatal injuries.
The device and any power plug connectors must not be disconnected while a voltage is applied to the
device. Failure to comply with this may cause arcing, which in addition to the risk of injury, also results
in a risk of damage or destruction of the device.
The fact that the status LED or other indicators are not illuminated does not indicate that the device
has been disconnected from the mains and is without voltage.
The heat sink and all other metal components can heat up to temperatures above 70 °C.
Touching these parts can result in local burns to the body parts concerned (cooling times and
clearance from neighbouring components must be complied with).
All work on the device, e.g. transportation, installation, commissioning and maintenance work must be
carried out by qualified experts (observe IEC 364 or CENELEC HD 384 or DIN VDE 0100 and
IEC 664 or DIN VDE 0110 and national accident prevention regulations). In particular, the general and
regional installation and safety regulations for work on high voltage systems (e.g. VDE) must be
complied with as must the regulations concerning correct use of tools and the use of personal
protection equipment.
During all work on the device, take care that no foreign bodies, loose parts, moisture or dust enter or
remain in the device (risk of short circuit, fire and corrosion).
Further information can be found in this documentation.

2. Qualified experts
For the purposes of these basic safety instructions, qualified personnel are persons who are familiar
with the assembly, installation, commissioning and operation of this product and who have the
relevant qualifications for their work.
Furthermore, the device and the associated accessories may only be installed and started up by
qualified electricians. An electrician is a person who, because of their technical training and
experience, has sufficient knowledge with regard to
• switching on, switching off, isolating, earthing and marking power circuits and devices,
• proper maintenance and use of protective devices in accordance with defined safety standards.
