Appendix04/07 AWB8230-1541GBUL ® Caution, Warnings and InstructionsWiring Warnings for Electrical Practices and Wire SizesThe Cautions, Warnings, and instructions in this sectionsummarize the procedures necessary to ensure an inverterinstallation <strong>com</strong>plies with Underwriters Laboratories ® guidelines.j Warning!Use 60/75 °C Cu wire only or equivalent.j Warning!Open Type Equipment.j Warning!Suitable for use on a circuit capable of delivering not morethan 5,000 rms symmetrical amperes:• 240 V maximum for DF51-322 and DF51-320 models.• 480 V maximum for DF51-340 models.j Warning!“Suitable for use on a circuit capable of delivering not morethan 5,000 rms symmetrical amperes, 480 V maximum.”For DF51 models.Circuit Breaker and Fuse SizesThe inverter’s connections to input power must include UL Listedinverse time circuit breakers with 600 V rating, or UL Listed fusesas shown in the table below.Fuse (class J)rated 600 VUL ListedFuse (class J)rated 600 VTerminal Tightening Torque and Wire SizeThe terminal screw dimensions for all DF51 inverters are listed inTable 42 (a Page 217) and Table 2 (a Page 4). Thisinformation is useful in sizing spade lug or ring lug connectors forwire terminations.When connecting wiring, use the tightening torque listed in theabove mentioned tables to safely attach wiring to the connectors.Determination of wire and fuse sizesThe maximum motor current in your application determines there<strong>com</strong>mended wire size. The following table gives the wire size inAWG. The “Power Lines” column applies to the inverter inputpower, output wires to the motor, the earth ground connection,and any other <strong>com</strong>ponent. The “Signal Lines” column applies toany wire connecting to the two green 7 and 8-position connectorsjust inside the front enclosure panel.<strong>Inverter</strong> ModelDF51-…InputVoltageMotor outputFuse(UL-rated, class J, 600 V)Wiring SizeRangeTorquekW HP A AWG ft-lbs Nm322-025 200 V 0.2 k 10 16 0.6 0.8322-037 0.4 m 10 16 0.6 0.8322-055 0.55 o 10 16 0.6 0.8322-075 0.75 1 15 14 0.9 1.2322-1K1 1.1 1 m 15 14 0.9 1.2322-1K5 1.5 2 20 (single ph.)12 0.9 1.215 (three ph.)322-2K2 2.2 3 30 (single ph.)10 0.9 1.220 (three ph.)320-4K0 4 5 30 12 0.9 1.2320-5K5 5.5 7 m 40 10 1.8 2.5320-7K5 7.5 10 50 8 1.8 2.5340-037 400 V 0.4 m 3 16 0.9 1.2340-075 0.75 1 6 16 0.9 1.2340-1K5 1.5 2 10 16 0.9 1.2340-2K2 2.2 3 10 16 0.9 1.2340-3K0 3 4 15 140 0.9 1.2340-4K0 4 5 15 14 0.9 1.2340-5K5 5.5 7 m 20 12 1.8 2.5340-7K5 7.5 10 25 12 1.8 2.5AWG = American Wire Gauge.
