2.2 Application as directed
All products which this documentation applies to are no household appliances but are
exclusively intended as components for re−utilisation for commercial use or
professional use in terms of IEC/EN 61000−3−2. They meet the requirements of the
Low−Voltage Directive 2014/35/EU and the requirements of the harmonised standards
of the IEC/EN 60034 series.
Only use the products under the operating conditions and power limits specified in this
documentation.
Do not use the brakes installed as fail−safe brakes. It cannot be ruled out that the braking
torque is reduced by disruptive factors which cannot be influenced.
¯ Drives
– ... must only be operated under the operating conditions and power limits
specified in this documentation.
– ... comply with the protection requirements of the EU Low−Voltage Directive.
Any other use shall be deemed inappropriate!
2.3 Foreseeable misuse
Impermissible applications:
¯ In a potentially explosive atmosphere
– Exception: special ATEX design
¯ In aggressive environments (acids, gases, vapours, dusts, or oils).
¯ Under water or in liquids
¯ Under radiation
2.4 Residual hazards
Protection of persons
¯ Risk of burns!
– Hot surfaces up to 140 °C during operation! Provide protection against contact.
¯ Highfrequency voltages can be capacitively transferred to the motor housing
through the inverter supply.
– Earth motor housing carefully.
¯ Risk of injury due to rotating shaft!
– Before working on the drive system, ensure that the motor is at a standstill.
¯ Danger of unintentional starting or electrical shocks!
– Connections must only be made when the equipment is deenergised and the
motor is at standstill.
– Installed brakes are no fail−safe brakes.
¯ Dangerous voltages at the power terminals, even if the plug is removed: residual
voltage >60 V!
