Before commencing the installation

• Disconnect the power supply of the device.

• Ensure that devices cannot be accidentally restarted.

• Verify isolation from the supply.

• Earth and short circuit the device.

• Cover or enclose any adjacent live components.

• Follow the engineering instructions (AWA/IL) for the 

device concerned.

• Only suitably qualified personnel in accordance with 

EN 50110-1/-2 (VDE 0105 Part 100) may work on this 
device/system.

• Before installation and before touching the device ensure 

that you are free of electrostatic charge.

• The functional earth (FE, PES) must be connected to the 

protective earth (PE) or the potential equalisation. The 
system installer is responsible for implementing this 
connection.

• Connecting cables and signal lines should be installed so 

that inductive or capacitive interference does not impair 
the automation functions.

• Install automation devices and related operating elements 

in such a way that they are well protected against 
unintentional operation.

• Suitable safety hardware and software measures should 

be implemented for the I/O interface so that an open 
circuit on the signal side does not result in undefined 
states in the automation devices.

• Ensure a reliable electrical isolation of the extra-low 

voltage of the 24 V supply. Only use power supply units 
complying with IEC 60364-4-41 (VDE 0100 Part 410) or 
HD384.4.41 S2.

• Deviations of the mains voltage from the rated value must 

not exceed the tolerance limits given in the specifications, 
otherwise this may cause malfunction and dangerous 
operation.

• Emergency stop devices complying with IEC/EN 60204-1 

must be effective in all operating modes of the automation 
devices. Unlatching the emergency-stop devices must not 
cause a restart.

• Devices that are designed for mounting in housings or 

control cabinets must only be operated and controlled 
after they have been installed and with the housing 
closed. Desktop or portable units must only be operated 
and controlled in enclosed housings.

• Measures should be taken to ensure the proper restart of 

programs interrupted after a voltage dip or failure. This 
should not cause dangerous operating states even for a 
short time. If necessary, emergency-stop devices should 
be implemented.

• Wherever faults in the automation system may cause 

injury or material damage, external measures must be 
implemented to ensure a safe operating state in the event 
of a fault or malfunction (for example, by means of 
separate limit switches, mechanical interlocks etc.).

• Depending on their degree of protection, frequency 

inverters may contain live bright metal parts, moving or 
rotating components or hot surfaces during and 
immediately after operation.

• Removal of the required covers, improper installation or 

incorrect operation of motor or frequency inverter may 
cause the failure of the device and may lead to serious 
injury or damage.

• The applicable national accident prevention and safety 

regulations apply to all work carried on live frequency 
inverters.

• The electrical installation must be carried out in 

accordance with the relevant regulations (e. g. with 
regard to cable cross sections, fuses, PE).

• Transport, installation, commissioning and maintenance 

work must be carried out only by qualified personnel 
(IEC 60364, HD 384 and national occupational safety 
regulations).

• Installations containing frequency inverters must be 

provided with additional monitoring and protective 
devices in accordance with the applicable safety 
regulations. Modifications to the frequency inverters 
using the operating software are permitted.

• All covers and doors must be kept closed during 

operation.

• To reduce the hazards for people or equipment, the user 

must include in the machine design measures that restrict 
the consequences of a malfunction or failure of the drive 
(increased motor speed or sudden standstill of motor). 
These measures include:

– Other independent devices for monitoring safety-

related variables (speed, travel, end positions etc.).

– Electrical or non-electrical system-wide measures 

(electrical or mechanical interlocks).

– Never touch live parts or cable connections of the 

frequency inverter after it has been disconnected from 
the power supply. Due to the charge in the capacitors, 
these parts may still be live after disconnection. Fit 
appropriate warning signs.
