6.6.1 Wiring Diagrams for Different Operating Altitudes
• Operation up to 2000 m (6560 ft) altitude: Each relay can operate at different phase voltages. See
• Operation above 2000 m (6560 ft) altitude: Operation with voltage above 50 V AC requires operation on the same phase volt-
age. See Illustration 19.
• Operation with mixed voltage (24 V) and high voltage is possible. High voltage must be on the same phase. See
