3.10. Connecting the Load
3.10.1. 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 Section 3.9.2).
•
Insulation rating of the wire should be at lease equivalent to the maximum Output
voltage of the Power Supply
•
Maximum wire length and voltage drop (design for 1V drop per lead).
•
Noise and impedance effects of the load wire (refer to Section 3.9.4).
3.10.2. Current Carrying Capacity
The load cables between the Power Supply Output and the load must be specified.
The cable connections must be secured to required torque spec. Failure to meet
these requirements could cause substantial voltage-drop power losses, terminal over-
heating, and insulation degradation.
The Output styles vary depending on the Output voltage range:
•
Platform A & B (Output Voltage Range: 7.5V-80V &100V-300V).
– Vertical Bus Bar Configuration
– 0.422 inch mounting hole
-
7.5V - 25V models have two mounting holes
-
30V - 300V models have one mounting hole
– Use 3/8 inch diameter bolt/nut.
•
Platform C (Output voltage range: 400V- 600V)
– Threaded-stud configuration
– M6 x1.0inch nut/washer size
The Output connections are protected with a metal cover. To connect the load cables,
remove the metal cover and connect the proper size cables with nuts and bolts.
Proper torque (as per bolt size) should be applied to any bolt/nut combination.
Typical cable sizes for load connections are shown below. Use cables that meet
requirements for current, voltage, length, temperature and termination.

WARNING
Turn Off the AC input power before making or changing any rear
panel connection. Ensure all live circuits are discharged and that all
connections are securely tightened before applying power.
