Operation
Where necessary, systems in which the devices are installed must be equipped with additional
monitoring and protective equipment according to the applicable safety requirements (e.g. legislation
concerning technical equipment, accident prevention regulations, etc.).
All covers must be kept closed during operation.
With certain setting conditions, the device or the motor which is connected to it may start automatically
when the mains are switched on. The machinery which it drives (press / chain hoist / roller / fan etc.)
may then make an unexpected movement. This may cause various injuries, including to third parties.
Before switching on the mains, secure the danger area by warning and removing all persons from the
danger area.
Due to its operation, the device produces noises within the audible frequency range. These noises
may cause long-term stress, discomfort and fatigue, with negative effects on concentration. The
frequency range or the noise can be shifted to a less disturbing or almost inaudible range by
adjustment of the pulse frequency. However, this may possibly result in derating (lower power) of the
device.
Maintenance, repair and decommissioning
Installation, maintenance and repair work must not be carried out unless the device has been
disconnected from the voltage and at least 5 minutes have elapsed since the mains was switched off!
(Due to charged capacitors, the equipment may continue to carry hazardous voltages for up to
5 minutes after being switched off at the mains). Before starting work it is essential to check by
measurement that all contacts of the power plug connections or the connection are voltage-free.
For further information, please refer to the manual for the device.
Disposal
The product and its parts and accessories must not be disposed of as domestic waste. At the end of
its life, the product must be properly disposed of according to the local regulations for industrial waste.
In particular, this product contains integrated semiconductor circuits (PCBs and various electronic
components, including high power capacitors). In case of incorrect disposal there is a risk of formation
of toxic gases, which may cause contamination of the environment and direct or indirect injuries (e.g.
chemical burns). In the case of high power capacitors, there is also a risk of explosion, with the
associated risk of injury.
5. Potentially explosive environment (ATEX, EAC Ex)
In order to operate or carry out installation work in potentially explosive environments (ATEX,
EAC Ex), the device must be approved and the relevant requirements and notes from the manual of
the device must be complied with.
Failure to comply can result in the ignition of an explosive atmosphere and fatal injuries.
• Only persons who are qualified, i.e. trained and authorised for all assembly, service,
commissioning and operation work on association with explosion hazard environments may work
with the devices described here (including the motors, geared motors, any accessories and all
connection technology).
