AC INPUT CORD
The AC input cord is the disconnect device for the power supply. The plug must be readily identifiable to the
operator. The input cord must be no longer than 3 m (9.84 feet). The AC cord size wire will depend on the
maximum power of the power supply.
The AC input cord we recommend is specified below, “AC Cord Specification”.
If you require a special cord, call our sales representative

LOAD WIRING
To select wiring for connecting the load to the power supply, consider the following factors:
x Insulation rating of the wire
x Current carrying capacity of the wire
x Maximum load wiring length for operation with sense lines
x Noise and impedance effects of the load lines
x Length, impedance and gauge size of the load lines
CURRENT CARRYING CAPACITY: As a minimum, load wiring must have a current capacity greater than
the output current rating of the power supply. This ensures that the wiring will not be damaged even if the
load is shorted. Table 2.1 shows the maximum current rating, based on 450 A/cm², for various gauges of wire
rate for 105qC operations. Operate at the maximum current rating results in an approximately 30qC
temperature rise for a wire operating in free air. Where load wiring must operate in areas with elevated
ambient temperatures or bundled with other wiring, use larger gauges or wiring rated for higher temperature.
