Operating Manual for XHR Series Power Supply

60 V to 600 V Models

The output connector for the 60 V to 600 V models is a 4-terminal, wire clamp 
connector located on the rear panel. Two of the terminals are for local sense 
connections. See 

Figure 2.5

. 

To prepare and connect the load wiring:

1. Strip insulation 0.35in. (9 mm) at the end of the wires.
2. Loosen the terminal screw, insert the stripped wire into the terminal, and tighten 

the screw securely.

Figure 2.5

Output Connector 

(For 60 V to 600 V models.)

WARNING

To protect personnel against accidental contact with hazardous voltages, ensure 
that the load, including connections, has no live parts which are accessible. Also 
ensure that the insulation rating of the load wiring and circuitry is greater than or 
equal to the maximum output voltage of the power supply.
