TDK AC Input Connector, 1500W models, AC Input Connector, 750W models, AC Input Cord

WARNING

Some components inside the power supply are at AC voltage even when the On/Off switch is in the “Off” position. To avoid electric shock hazard, disconnect the line cord and load and wait two minutes before removing cover.

3.7.1 AC Input Connector, 1500W models

The AC input connector is a 3-Terminal wire clamp located on the rear panel. Use suitable wires and tightening torque as follows:

1.Wire diameter: 12AWG or 10AWG.

2.Tightening torque: 6.5 - 7.0 Lb-inch.

3.7.2 AC Input Connector, 750W models

An IEC connector is provided on the rear panel for connecting the unit to the AC power source with an AC cord. The IEC connector also provides the safety ground connection while the AC cord is plugged into an appropriate AC receptacle.

WARNING

The AC input cord is the disconnect device of the power supply. The plug must be readily identifiable and accessible to the user. The AC input cord must be no longer than 3m.

3.7.3 AC Input Cord

Refer to Section 1.3.4 for details of the AC input cords recommended for the 750W and the 1500W models.

3.7.4AC Input Wire Connection, 1500W models

1.Strip the outside insulation of the AC cable approx. 10cm (3.94 inches). Trim the wires so that the ground wire is 10mm (0.4 inches) longer than the other wires. Strip 14mm (0.55 inches) at the end of each of the wires.

2.Unscrew the base of the strain relief from the helix-shaped body. Insert the base through the outside opening in the AC input cover and screw the locknut securely (11-14 Lb-inch.) the base, from the inside.

3.Slide the helix-shaped body onto the AC cable. Insert the stripped wires through the strain re- lief base until the outer cable jacket is flush with the edge of the base. Tighten (16-18 Lb-inch.) the body to the base while holding the cable in place. Now the cable is securely fastened in- side the strain relief. Refer to Fig. 3-2.
