Chapter 3 - Power Connections
The ACS 300 is designed for use on 200 to 240 V and on 380 to
480 V supplies. Refer to tables 3-1 and 3-2 to see allowable
voltages.
WARNING! NEVER connect voltage higher than 240 V to the
mains input terminals of the 200 to 240 V ACS 300.
Note! The Factory setting of the 400 V series ACS 300 supply
voltage is 480 V. If your voltage is much lower than 480 V, for
example 380 V or 400 V, you may get an undervoltage fault
message when first using the ACS 300. After connecting the
mains cabling, change the value to correspond to the mains
voltage. Press the Start/Stop key to reset the fault message.
Mains Cable
Note! A three-conductor screened cable (single phase and
neutral with protective earth) or four-conductor (three-phase with
protective earth) are recommended for the mains cabling, see
Figure 3-1. Dimension the cables and fuses in accordance with
the input/output current. Refer to Table 3-1.
Always pay attention
to local legislation when sizing the cables and fuses.
