DC Floating Voltage:

No output terminal may be more than 240 Vdc from any other terminal or from chassis ground. Also, no overvoltage terminal may be more than 240 Vdc from any other terminal or chassis ground.

Remote Sense Capability: (See wire size selection, page 47 and remote voltage sensing, page 48)

Outputs can maintain specifications with up to 1 volt drop per load lead except that the maximum voltage at the output terminals must not exceed the rated output voltage + 1 volt (see Figure 4-6). If the steady state voltage drop exceeds approximately 1.5 V on either load lead when remote sensing, a circuit will trip the OVP.
