Product
Observe the warning signs on the product!
Dangerous electrical voltage
Before working on the product, check whether all power connections are
deenergized!
After mains disconnection, the power terminals carry the hazardous
electrical voltage for the time specied next to the symbol!
Electrostatic sensitive devices
Before working on the product, the sta must ensure to be free of
electrostatic charge.
High leakage current
Carry out xed installation and PE connection in compliance with the
following standard:
ENIEC61800-5-1/ENIEC60204-1
Hot surface
Use personal protective equipment or wait until the device has cooled
down!
Protection of the machine/system
• Drives can reach dangerous overspeeds, e.g. from setting high output frequencies for
motors and machines which are not suitable. The inverters do not provide any protection
against such operating conditions. Use additional external components for this purpose.
• Only switch the contactor in the motor cable when the inverter is inhibited. Switching them
when the inverter is enabled is only permissible when no monitoring components respond.
Motor
In the event of a short circuit of two power transistors, a residual movement of up to 180°/
number of pole pairs on the motor may occur (e.g. 4-pole motor): Residual movement max.
180 °/2=90°).
Residual hazards
The user must take the residual hazards mentioned into consideration in the risk assessment
for his/her machine/system. If the above is disregarded, this may result in injuries to persons
and material damage!
DANGER!
Dangerous electrical voltage
During operation and up to 20 minutes after power-o, hazardous electrical voltages may be
present at the connections of the product.
The leakage current against earth (PE) is > 3.5 mA AC or > 10 mA DC.
Possible consequences
• Death or serious injury from electric shock
Protective measures
• Any work on the product must only be carried out in a deenergized state.
• Check that no voltage is present!
• After switching o the mains voltage, observe the signs on the product.
• After switching o, wait until the drive is at a standstill.
• Implement the measures required by EN IEC 61800-5-1 or EN IEC 60204-1, i.e. xed
installation and standards-compliant PE connection.
Degree of protection - Protection of persons and device protection
Information applies to the mounted and ready-for-use state.
Motor protection
With some settings of the inverter, the connected motor can be overheated.
• E.g.via the operation of self-ventilated motors at low speeds over a long period.
• E.g. by operating DC-injection braking over a long period.

EMC-compliant installation
The drive system of inverter and drive comply with the EMC Directive 2014/30/EU if they are
installed according to the specications of CE-typical drive systems. These guidelines should
also be followed in installations requiring FCC Part 15 or ICES 001 compliance. The structure
at the installation location must support the EMC-compliant installation with shielded motor
cables.
• Please use suciently conductive shield connections.
• Connect the housing with shielding eect to the grounded mounting plate with a surface as
large as possible, e.g. of inverters and RFI lters.
• Use central earthing points.
The following example shows the eective wiring.
