NOTE
Transformer voltage taps must be selected to match the incoming supply voltage.
See section on Mains Power Supply Connection.
Power required: 3.0 kW, 15.5 amperes full load at 208 V~, 60 Hz and
2.6kW, 13 amperes full load at 200 V~, 50 Hz.
58 amperes starting current, 68 amperes locked-rotor current.
Power Cord Connector: NEMA L6-20P (2 pole, 3 wire, 20 A, 250 V~) male plug
to connect to customer’s receptacle.
Power Conductor Requirements for hard wiring (if not using the compressor power cord):
Use 12 AWG (3.3 mm
2
) copper wire rated at 250 V~ minimum, protected with oil-
resistant insulation. Two power leads and one grounding conductor are required.
Power should be provided through a separately fused safety switch with 20-ampere fuses.
Fuses are SLO-BLO, type T. Fuse ratings are 250 volts, 0.4 ampere, 0.63 ampere, 1.0 ampere
and 5.0 amperes. See the Description and the Parts sections.
Cold Head Receptacle: Receptacle on the compressor front panel used with a cold head cable
provides power to the cold head.
Accessory Receptacle on the compressor used with an optional accessory cable provides
remote on/off switching capability.
Control Logic provides:
Automatic restart after power interruption
Remote start/stop capability (using optional accessory cable).
