120 VAC low-voltage closing 2-pin input and 2-pin output receptacles (KME6-1775-A) and 240 VAC low-voltage
closing with 2-pin input and 2-pin output receptacle (KME6-1775-D).
WARNING: Hazardous voltage. Before applying
power to the control, confirm that male pins of
the input power receptacle are electrically insulated to
prevent unintentional contact with 120V AC voltage.
Failure to do so may result in severe personal injury or
death. T372.0
DANGER: Hazardous voltage. Do not connect
potential transformer low-voltage secondaries to
the control through cables or other wiring until the unit is
installed in the field. Transformer high-voltage primary
windings will become live when 120V AC is applied to
the control from an alternate source if the transformer
secondary is connected. Failure to comply may result in
severe personal injury or death. T371.1
Note: Terminal Block positions TB7-3 and TB7-4 are
factory-jumpered together.
Terminal Block positions TB7-5 and TB7-6 are
factory-jumpered together.
