1-18 | ni.comChapter 1 Installation and PreparationEven if you turn the output off or turn the POWER switch off, if the bleeder on/offsetting (CF11) is set to oFF, the voltage that was present when the output was on willremain at the output terminals. Set the bleeder on/off setting to on before you touchthe sensing terminals.Regardless of whether local sensing or remote sensing is used, be sure to attach thesensing terminal cover before turning the POWER switch on.If the sensing cables come loose, the output voltage across the load may become unstable, andan excessive voltage may be applied to the load. If an appropriate OVP trip point is set, the OVPwill trip before an excessive voltage is generated.When you are finished with remote sensing, return to local sensing mode.Figure 1-19.
