DC Floating Voltage:
No output terminal may be more that 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 pages 50 - 52):
Outputs can maintain specifications with up to 10 volt total in the remote sense leads.
