What This Chapter Contains
This chapter contains information that is relevant to the electrical installation of the PIU and drives in an electrical
cabinet such as:
Mains power supply and protective earthing
EMC compliance
Regenerative Brake Resistor Selection
Drive and motor connection
5.2
Mains Power Supply
The following components are required for connection to the mains supply to the PIU:
Isolation switch to allow correct isolation of the system from the power supply
Circuit breakers or fuses to protect cables, filter and drive
EMI filter to limit electrical noise on the mains supply
Line reactor to allow proper function of the PIU, and to limit conducted harmonics on the mains
supply.
Contactor(s) for safety under E-Stop conditions.
The EMI filter and line reactor are also required for EMC compliance; refer to
5.5 Installations Conforming to the
for details on the recommended EMC compliant installation.
The AMD5x PIUs and Drives are suitable for use on supplies of installation overvoltage Category III, according to
IEC 61800-5-1. This means they may be connected permanently to the supply at its origin in a building, but for
machine installations closer to primary distribution supply (overhead cables etc.) additional over-voltage
suppression (transient voltage surge suppression) must be provided to reduce Category IV to Category III.
3 Phase AC Voltage Supply
5.2.1
The three phase AC supply voltage range must be within the limits specified in
Section 10.4 Electrical
The AMD5x PIU has mains detection circuitry and errors will be generated if the PIU is operated outside
specifications, or in the event of loss of one or more phases of the mains supply. The PIU cannot be operated
with a single phase supply. The mains supply to the PIU can be connected in either phase rotation
.
