2.7.2 Making Load Connections (continued)
150V to 600V Models
WARNING
To protect personnel against accidental contact, install a physical shield for
the connections at any load attached to a high voltage power supply.
The 150V to 600V models have a 4-terminal, wire clamp output connector. See Figure 2.7-4 for a labeled
drawing of the wire clamp connector. To prepare and connect the load wiring:
1. Strip 0.4" (10 mm) at the end of each of the wires.
2. To connect the wiring, loosen each terminal screw, insert a stripped wire into the terminal, and tighten
the screw securely.

2.7.3 Inductive Loads
To prevent damage to the power supply from inductive kickback, connect a diode across the output. The diode
must be rated at greater than or equal to the supply’s output voltage and have a current surge rating greater than
or equal to the supply's output rating. Connect the cathode to the positive output and the anode to return.
Where positive load transients such as back EMF from a motor may occur, connect a transorb or a varistor
across the output to protect the power supply. The breakdown voltage rating for the transorb or varistor must be
approximately 10% higher than the rated supply output.
