Electrical connection
Before performing any work on the electrical system:
DANGER
Life-threatening voltages inside the frequency
inverter housing!
Contact can lead to serious injuries or death.
Never open the FI housing in operation! Switch
off the main switch and secure it against being
switched on again.
Wait for at least 5 minutes until all capacitors
have been discharged!
Before switching on again, close the FI housing.
DANGER
As soon as the VARIPACK frequency inverter is
energized, the capacitors in the FI DC link are
charged.
From this moment on, all electrical components
in the VARIPACK frequency inverter present
risks!
The operation of the VARIPACK frequency inverter re-
quires the following electrical connections:
• VARIPACK earth connection.
• VARIPACK power connections (power cable and
motor cable)
• VARIPACK control connections.
For the layout of the cable diameters, fuses and tight-
ening torques of the earth and power connections, see
table 3, page 49.
