Fig.3-2: Stripped Wires installed in Strain Relief
3.7.1 AC Input Connector, 1500W models
The AC input connector is a 3
ated on the rear panel. Use suitable wires and
tightening torque as follows:
Wire diameter: 12AWG or 10AWG.
3.7.2 AC Input Connector, 750W models
An IEC connector is provided on the rear panel for connecting the unit t
o 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.
Refer to Section 1.3.4 for details of the AC input cords recommended fo
AC Input Wire Connection, 1500W models
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 inche
the end of each of the wires.
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
shaped body onto the AC cable. Insert the stripped wires through the strain r
lief base until the outer cable jacket is flush with the edge of the base. Tighten (16
the body to the base while holding the cable in place. Now the cable is sec
side the strain relief. Refer to Fig. 3
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.
Some components inside the power supply are at AC vol
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.
