Unit Voltage Phasing
It is important that proper rotation of the compressors
be established before the unit is started. Proper motor
rotation requires confirmation of the electrical phase

Technical Data
WARNING! It is imperative that L1, L2, and L3 in the
starter be connected in the A-BC phase sequence to
prevent equipment damage due to reverse rotation.
WARNING! To prevent injury or death due to
08
electrocution, take extreme care when performing
(V/Ph/Hz)
service procedures with electrical power energized.
