2.5.3 Electrical connection of power unit
The following information relates to all power connections to the frequency inverter. This includes:
• Mains cable connection X1 (L1, L2/N, L3, PE)
• Motor cable connection X2 (U, V, W, PE)
• Braking resistor connection X3 (B+, B-)
• Link circuit connection (B+, DC-)
When connecting the device, please note the following:
1. Ensure that the mains supply provides the correct voltage and is suitable for the current
required(Chap. 7 "Technical data")
2. Ensure that suitable electrical fuses with the specified nominal current range are installed between
the voltage source and the device.
3. Mains cable connection: to terminals L1-L2/N-L3 and PE (depending on device)
4. Motor connection: to terminals U-V-W and PE
5. The shield of a shielded motor cable must also be connected to a large area of the metal shielding
bracket of the EMC Kit, however, at least to the electrically conducting mounting surface of the
control cabinet.
The use of ring cable lugs is recommended for connecting to PE.
Information
