All equipment leaves the factory wired on 0V tap. For 08V operation, reconnect from 0V to 08V tap. The acceptable operating voltage range for the 0V and 08V taps are: An 8 gauge copper, color-coded thermostat cable is recommended. The connection points are shown in this Manual. See Table below. TABLE OPEATIN VOLTAE ANE TAP ANE 0V 6 08V 0 87 NOTE: The voltage should be measured at the field power connection point in the unit and while the unit is operating at full load (maximum amperage operating condition). Low Voltage onnection These units use a -volt A low voltage circuit. The T terminal is the V transformer output, and the terminal is the VA hot terminal for the operation of the equipment. T and are connected with brass jumper bar which can be removed and T and connected to external N (normally closed) contact such as a fire/smoke detector that will cause immediate shutdown of the equipment upon activation. terminal is grounded. terminal is the fan input.
