2.2 Applicaon as directed
•The product serves as a component for the control of three-phase AC motors and servo
motors.
•The product must only be actuated with motors that are suitable for the operaon with
inverters.
•The product is not a household appliance, but is only designed as electrical equipment for
commercial or professional use in terms of EN 61000−3−2.
•The product is exclusively suitable for installaon in control cabinets or similarly closed
operang areas.
•The product must only be operated under the operang condions prescribed in this
documentaon.
•The product meets the protecon requirements of 2014/35/EU: Low-Voltage Direcve.
•The product is not a machine in terms of 2006/42/EC: Machinery Direcve. With the
excepon of all funconal safety funcons.
•Commissioning or starng the operaon as directed of a machine with the product is not
permied unl it has been ensured that the machine meets the regulaons of the EC
Direcve 2006/42/EC: Machinery Direcve; observe EN 60204−1.
•Commissioning or starng operaon as directed is only permissible if the EMC Direcve
2014/30/EU is complied with.
•As the product may cause EMC interferences in residenal areas, the operator is
responsible for taking interference suppression measures.

2.4 Residual hazards
Product
Observe the warning labels on the product!
DANGER!
Danger to life due to electrical voltage!
The product's power connecons can sll be carrying voltage when the mains supply has been
switched oî„«.
Possible consequences: Death, severe injury, or burns
▶Do not touch the power connecons immediately.
â–¶Take note of the corresponding warning plates on the product.
▶Check power terminals for isolaon from supply.
Electrostac sensive devices:
Before working on the product, the sta must ensure to be free of electrostac charge!
WARNING!
Dangerous electrical voltage
Device error causes an overvoltage in the system.
▶For a voltage supply with DC 24 V (± 20 %), use only a safely separated power supply unit
according to the valid SELV/PELV requirements.
Motor protecon
With some sengs of the inverter, the connected motor can be overheated.
•E. g. by longer operaon of self-venlated motors at low speed.
•E. g. by longer operaon of DC-injecon braking.
Dangerous electrical voltage:
Before working on the product, make sure there is no voltage applied to the power terminals!
Aer mains disconnecon, the power terminals will sll carry the hazardous electrical voltage for the me given next to the
symbol!
High leakage current:
Carry out xed installaon and PE connecon in compliance with:
EN 61800−5−1 / EN 60204−1
Protecon of the machine/system
Drives can reach dangerous overspeeds.
•E. g. by seng high output frequencies in connecon with motors and machines not
suitable for this purpose.
•The inverters do not provide protecon against such operang condions. For this
purpose, use addional components.
Switch contactors in the motor cable only if the controller is inhibited.
•Switching while the inverter is enabled is only permissible if no monitoring funcons are
acvated.
Hot surface:
Use personal protecve equipment or wait unl the device has cooled down!
Motor
If there is a short circuit of two power transistors, a residual movement of up to 180°/number
of pole pairs can occur at the motor! (e. g. 4-pole motor: residual movement max. 180°/2 =
90°).
Safety instrucons
Residual hazards

NOTICE
High input voltage at the device.
Destrucon of the device.
â–¶Observe maximum permissible input voltage.
â–¶Fuse device at the input against too high input voltage.
NOTICE
Short circuit at the device due to electrostac discharge.
Destrucon of the device.
▶The personnel must be free of electrostac charge prior to working on the device.
Degree of protecon - protecon of persons and device protecon
•Informaon applies to the mounted and ready-for-use state.
•Informaon does not apply to the wire range of the terminals.
-Terminals that are not wired have low protecon against physical contact.
-Terminals for large cable cross-secons have lower classes of protecon, e. g. from
15 kW IP10 only.
