Electrical installation
An overlay of the electrical connections / terminals is included on the back page of this manual.
4.1 AC supply requirements
Voltage:
100 V drive: 100 V to 120 V ±10 %
200 V drive: 200 V to 240 V ±10 %
400 V drive: 380 V to 480 V ±10 %
Number of phases: 3
Maximum supply imbalance: 2 % negative phase sequence (equivalent to 3 % voltage imbalance
between phases).
Frequency range: 45 to 66 Hz.
For UL compliance only, the maximum supply symmetrical fault current must be limited to 100 kA.
On the size 2 110 V drives or when connecting single phase to a dual rated 200 V unit, the
supply should be connected to L1 and L3. Also the DC bus (-) terminal on 110 V drives
has no internal connection. The 110 V drives use a voltage doubler circuit on the input,
therefore the default for
Motor Rated Voltage
(Pr
08
) is 230 V.
