Electrical Installation
5.5 Mains Connection
DANGER
Disconnect the frequency inverter from mains voltage and protect it against being ener-
gized unintentionally.
Verify that the frequency inverter is discharged.
Wait for some minutes until the DC link capacitors have discharged before starting to
work at the unit.
When the frequency inverter is disconnected from power supply, the mains, DC-
voltage and motor terminals may still be live for some time.
The mains fuses and cable cross-sections are to be selected according to EN 60204-1 and DIN VDE
0298 Part 4 for the nominal operating point of the frequency inverter. According to UL/CSA, approved
Class 1 copper lines with a temperature range of 60/75°C and matching mains fuses are to be used
for the power cables. The electrical installation is to be done according to the device specifications and
the applicable standards and directives.
CAUTION
The control, mains and motor lines must be kept physically separate from one another.
The cables connected to the frequency inverters may not be subjected to high-
insulation tests unless appropriate circuitry measures are taken before.
Minimum Torque to tighten the screws: 0.5 Nm (4.6 lb-in)
Maximum
Torque to tighten the screws: 0,6 Nm (5,3 lb-in)
Recommended sizes of Mains fuses F1 are described in the technical data chapter 11.2 “Device data”.
: Only for in DC link connections.
Comply with the notes on cable cross-sections in chapter 5.4 "Dimensioning of conductor cross-
section".
Mains terminals:
0,2 … 4 (flexible cable with sleeve)
0,2 … 6 (rigid cable)
