IM 1029-2 Magnitude™ Frictionless Centrifugal Chillers – Model WMC 25
Case 3, WMC 250D, 290D, 400D Field Power Wiring
Case 3 adds the combo harmonic filters. The standard line reactors are shipped in the unit and are removed
and discarded in the field. Field wiring to the harmonic filter would be the same size as the incoming lines.
Figure 20 shows the optional multi-point connection to two disconnect switches. The standard would be a
single-point connection to a single disconnect switch.
