3-Wire vs. 4-Wire
Configurations ProDySC models are available for use with either 3-wire (L1, L2, L3) or 4-wire
(L1, L2, L3, N) sources. The input N conductor must be connected to 4-wire
models for proper operation. Do not connect a N conductor to 3-wire models
.
3- Wire Models Bulletin 1608P part numbers containing V3 are configured for 3-wire source (L1,
L2, L3) and 3-wire loads (X1, X2, X3). Do not connect a N conductor to 3-wire
models.
Figure 5 shows the 3-wire ProDySC system wiring schematically,
including the recommended Bypass Switch .

Note: The 3-wire ProDySC models rated greater than 240V have not been evaluated by
Underwriter's Laboratories, Inc.(R) for connection to a corner-grounded or ungrounded delta
power source. Contact Rockwell Automation Technical Support for assistance.
