† The MFM has its own individual wall power unit located at the station
and therefore is not added to the unit load calculation.
‡ Up to two DSSs (one DSS per MLX-28D or MLX-20L) can be
powered from each control unit carrier. For example, a three-carrier
system can have six system operator positions, each with one DSS
powered from the control unit.
If the unit load for slots 5 and 6 is less than or
equal to 27, auxiliary power is sufficient for the
carrier.
If the unit load for slots 5 and 6 is more than
27, continue to step 9.
