AC supply requirements
Use either of the following types of AC supply:
• Single-phase (ie. between one phase and neutral of a
star-connected three-phase supply)
• Between two phases of a delta-connected three-phase supply
(one phase can be grounded)
Ground connections
The Drive must be connected to the system ground of the AC supply. The
ground wiring must conform to local regulations and codes of practice.
Refer to Wiring recommendations later in this chapter.
Warning
The ground loop impedance must conform to the
requirements of local safety regulations. The ground
connections must be inspected and tested at appropriate
intervals.
Power cables
Warning
Wiring must be in accordance with local regulations and
codes of practice. The table below shows typical cable sizes
for power input and output wiring. In the event of a
conflict, local regulations prevail.
Use pvc-insulated cable having copper conductors as shown in Table 4–1.
