precondion for safe and trouble-free operaon and for obtaining the product features

specied.

Please observe the specic safety informaon in the other secons!

2.1 Basic safety instrucons

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 o.

Possible consequences: Death, severe injury, or burns

▶Do not touch the power connecons immediately.

▶Take note of the corresponding warning plates on the product.

▶Check power terminals for isolaon from supply.

DANGER!

Dangerous electrical voltage

Possible consequences: Death or severe injuries from electric shock

▶Any work on the device must only be carried out in a deenergized state.

▶Aer switching o the mains voltage, observe the signs on the product.

Personnel

Only qualied and skilled personnel are allowed to work with the product. IEC 60364 and/or

CENELEC HD 384 dene the qualicaons of these persons as follows:

product.

•They possess the appropriate qualicaons for their tasks.

•They are familiar with all regulaons for the prevenon of accidents, direcves, and laws

applicable at the locaon and are able to apply them.

Process engineering

The procedural notes and circuit details described are only proposals. It is up to the user to

check whether they can be adapted to the parcular applicaons. Lenze does not take any

responsibility for the suitability of the procedures and circuit proposals described.

Device protecon

•The maximum test voltage for insulaon tests between a control potenal of 24 V and PE

must not exceed 110 V DC (EN 61800−5−1).

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.

2.3 Handling

•Connect/disconnect all pluggable terminals only in de-energized condion.

•Only remove the product from the installaon in the de-energized state.

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 o.

Possible consequences: Death, severe injury, or burns

▶Do not touch the power connecons immediately.

▶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.

▶Observe maximum permissible input voltage.

▶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.
