3.7 CONNECTING THE LOAD
WARNING
Turn off the AC input power before making or changing any rear panel
connection. Ensure that all connections are securely tightened before
applying power. There is a potential shock hazard when using a power
supply with a rated output greater than 40V.
3.7.1 Load Wiring.
The following considerations should be made to select wiring for connecting the load to the power supply:
* Current carrying capacity of the wire (refer to 3.7.2).
*Insulation rating of the wire should be at least equivalent to the maximum output voltage of the power
supply.
*Maximum wire length and voltage drop (refer to 3.7.2).
*Noise and impedance effects of the load wiring (refer to 3.7.3).
3.7.2 Current Carrying Capacity
Two factors should must be considered while selecting the wire size. 1.Wires should be at least heavy
enough not to overheating while carrying the power supply load current at the rated load, or the current
that would flow in the event the load wires were shorted, whichever is greater.
2.Wire size should be selected to enable voltage drop per lead to be less than 1.0V at the rated current.
Please refer to Tables 3-2 and 3-3 for maximum wire length to limit the voltage drop in American and
European dimensions respectively.

For currents not shown in Tables 3-2 and 3-3 , use the formula :
Maximum length=1000/(current*resistivity)
Where current is expressed in ampers and resistivity in ohms/km or ohms/1000ft.
