FPS-S1U Instruction Manual

10.7.3 Making the load connections

!WARNING

Hazardous voltages may exist at the outputs and the load connections when using a power supply with a rated output greater than 40V. To protect personnel against accidental contact with hazardous voltages, ensure that the load and it's connections has no accessible live parts. Ensure that the load wiring insulation rating is greater than or equal to the maximum output voltage of the power supply.

The load wires should be properly terminated with terminals securely attached. DO NOT use unterminated wires for load connection at the FPS-S1U.
