HAZARDOUS VOLTAGE!
HIGH VOLTAGE IS PRESENT AT THE TERMINAL BLOCK
OR UNIT MOUNTED DISCONNECT SWITCH.
To prevent injury or death from electrocution, it is the re-
sponsibility of the technician to recognize this hazard and
use extreme care when performing service procedures with
the electrical power energized.
[ ] Observe the ABC and CBA phase indicator lights on the
face of the sequencer. The ABC indicator light will glow if
the phase is ABC. If the CBA indicator light glows, open
the disconnect switch or circuit protection switch and re-
verse any two power wires.
[ ] Restore the main electrical power and recheck the phas-
ing. If the phasing is correct, open the disconnect switch or
circuit protection switch and remove the phase sequence
indicator.
