IM 1029-2 Magnitude™ Frictionless Centrifugal Chillers – Model WMC 27
Case 5, WMC 145D – 150D Field Power Wiring
Case 5 adds remote-mounted combo harmonic filters. In these model WMCs the fuses are located in the
compressor. Field wiring is run from the disconnect switch load side to the power block in the remote filter.
The standard line reactors are shipped in the unit and are removed and discarded in the field. A shipped loose
power block is field mounted in their former location and one side is wired to the remote filter. The wires that
originally ran from the line reactor up to the compressor are now connected to the other side of the power
block.
NOTE: the fuses and compressor shown in the “Chiller” block are located in the compressors on these
models, not in the power panel. The wire routing is shown in Figure 22.
