Handling and installation
Warning!
Damaged or destroyed components must not be put into operation because they may be a
health hazard.
The frequency inverters are to be used in accordance with the documentation as well as the applica-
ble directives and standards.
It must be handled carefully and protected against mechanical stress.
Do not bend any components or change the isolating distances.
Do not touch electronic components or contacts. The devices are equipped with components which
are sensitive to electrostatic energy and can be damaged if handled improperly. Any use of damaged
or destroyed components shall be considered as a non-compliance with the applicable standards.
Removal of seals from the housing can result in invalidation of warranty.
Do not remove any warning signs from the device.

Electrical Installation
Warning!
Before any assembly or connection work, discharge the frequency inverter. Verify safe iso-
lation from power supply.
Do not touch the terminals because the capacitors may still be charged.
Comply with the information given in the operating instructions and on the frequency in-
verter label.
Follow the safety rules applying to work on electrical equipment.
Follow the safety rules applying to work on electrical equipment:
− Isolate: Isolate the installation from all possible sources of electrical power.
− Secure against reconnection. Only the persons working on the installation may re-commission the
relevant part of the installation.
− Verify there is no electrical power: Using a measuring instrument or voltage tester, ensure there is
no voltage against ground on the relevant plant component.
− Ground and short-circuit: Starting from the ground terminal, connect all conductors to one anoth-
1)
er.
− Cover und shield neighboring live parts: By covering, shielding or isolation of energized plant com-
ponents contact with such parts is to be prevented.
1)
Deviations from this are possible in certain circumstances.
When working at the frequency inverters, comply with the relevant accident prevention regulations,
the applicable standards BGV A2 (VBG 4), VDE 0100, standards governing work on systems with dan-
gerous voltages (e.g. DIN EN 50178) and other national directives.
Comply with the electrical installation instructions given in the documentation as well as the relevant
directives.
Responsibility for compliance with and examination of the limit values of the EMC product norm DIN
EN 61800-3 for variable-speed electrical drive mechanisms is with the manufacturer of the industrial
plant or machine. The documentation contains information on EMC-conforming installation.
The cables connected to the frequency inverters may not be subjected to high-voltage insulation tests
unless appropriate circuitry measures are taken before.
Do not connect any capacitive loads.
