1. General
Do not use defective devices or devices with defective or damaged housing or missing cover (e.g.
blind plugs for cable inlets). Otherwise, there is risk of serious or fatal injuries caused by electric shock
or bursting electrical components such as powerful electrolytic capacitors.
Unauthorized removal of covers, improper use, incorrect installation or operation brings about the risk
of serious personal injury or material damage.
There may be live, bare, moving or rotating parts or hot surfaces during operation and depending on
the degree of protection of the devices.
The device operates at dangerous voltages. Dangerous voltage may be present at the supply lines,
terminal strips and PCBs of all connecting terminals (e.g. power input, motor connection) even if the
device is not working or the motor is not rotating (e.g. caused by electronic disable, jamming of the
drive or a short circuit at the output terminals).
The device is not equipped with a main power switch and therefore is always live when connected to
the power supply. Therefore voltages may also be present in a connected motor at standstill.
Even if the drive unit has been disconnected from the line supply, a connected motor may rotate and
possibly generate a dangerous voltages.
If you come into contact with dangerous voltages such as these, there is risk of 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 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 power grid and is de-energized.
The heat sink and all other metal components can heat up to temperatures above 70°C.
Touching parts such as this can result in local burns to the body parts concerned (cooling times and
clearance from neighboring components must be adhered to).
All work on the device such as transportation, installation, commissioning and maintenance 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.
When working on the device, make sure that no foreign bodies, loose parts, moisture or dust enter or
remain in the device (risk of short circuit, fire and corrosion).
Additional information can be found in this documentation.
