transformer, while the single phase version can be installed on the transformer secondary.
Refer to the Voltage Snubber instruction manual (available at
) for details.

High Voltage Connections
2.3.1
Initial Selection of AC Input Voltage
The AC voltage supplied to the power controller should be at least 1.1 times higher than the
maximum DC voltage required by the CEDI module(s). The AC voltage is single-phase and it
can range from 220 VAC to 660 VAC.
For example:
If the maximum DC voltage required by a CEDI module is 300 VDC, then the input to the
controller must be at least 330 VAC. The maximum design input voltage is 660 VAC. The
unit can tolerate input voltage variations of +/- 10%. If the design input voltage is greater than
660 VAC,
then typical voltage variations can result in voltages outside the unit’s operating
conditions.
2.3.2
High Voltage Connections
AC and DC power connections must be made as described in Table 1. Figure 6 shows a basic
illustration of these connections.
