1.5 Electrical Connection
Warning! Before any assembly or connection work, discharge the frequency in-
verter. Verify that the frequency inverter is discharged.
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 inverter label.
When working at the frequency inverters, comply with the applicable standards BGV
A2 (VBG 4), VDE 0100 and other national directives. Comply with the electrical instal-
lation instructions given in the documentation as well as the relevant directives. The
manufacturer of the industrial machine or plant is responsible for making sure that
the limit values specified in the EMC product standard EN 61800-3 for electrical vari-
able-speed drives are complied with. 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 meas-
ures are taken before. Otherwise the unit may be damaged.
1.6 Information on Use
Warning! The frequency inverter may be connected to power supply every 60 s.
Consider this for a jog operation of a mains contactor. For commission-
ing or after an emergency stop, a non-recurrent, direct restart is permis-
sible.
After a failure and restoration of the power supply, the motor may start
unexpectedly if the AutoStart function is activated. Install protective
equipment if personal injury or material damage is possible.
Before commissioning and start of normal operation, make sure to fix all
covers and check all terminals. Check the additional monitoring and
protective devices according to EN 60204 and applicable the safety di-
rectives (e.g. Working Machines Act, Accident Prevention Directives
etc.).
No connection work may be performed, while the system is in operation.
1.7 Maintenance and Service
Warning! Unauthorized opening and improper interventions can lead to personal
injury or material damage. Repairs on the frequency inverters may only
be carried out by the manufacturer or persons authorized by the manu-
facturer. Check protective equipment regularly.
