Factory-Installed Compressor Motor Starter - York YK Manual

Guide Specifications (Cont'd)
JOHNSON CONTROLS
(Optional) A harmonic filter that limits electrical power supply distortion from the variable
speed drive in order to help the building comply with the guidelines of IEEE STD. 519-
2014 shall be provided. The filter shall be unit mounted within the same NEMA 1 enclo-
sure and shall be UL listed. The following digital readouts shall be provided at the chiller
unit control panel as part of the filter package:
• Input KVA
• Total power-factor
• 3-phase input voltage
• 3-phase input current
• 3-phase input voltage total harmonic distortion (THD)
• 3-phase input current total demand distortion (TDD)
• Self diagnostic service parameters
Separate meters for this information shall not be acceptable.
