Output Terminals
The output and sense terminals are duplicated on the rear panel terminal blocks and are marked
+O/P, −O/P, +S and −S. These connections are paralleled with their front panel equivalents.
Switch the LOCAL/REMOTE switch to REMOTE when remote sensing is required. When the rear
panel Output terminals are used, the use of remote sense is always recommended to ensure that
output regulation is maintained within specification; connections can be made to either the front or
the rear remote sense terminals but never to both pairs of terminals at the same time. Switch back
to LOCAL when remote sensing is not in use.
Analogue Remote Control (XPF 60-20A only)
Connections CV and CC provide analogue control of the Output Voltage and Current Limit
respectively when slide switches CV and CC are set to Remote. These inputs, and their common
return signal (RTN), are isolated from the output; the isolation rating with respect to the output is
300V max. The input scaling can be set independently, by intermal links, as 0 to 5 Volts (the factory
default) or 0 to 10 Volts for 0 to 100% of maximum output. Maximum permissible input is 60V. CV
and CC can be used independently or together.
Return slide switches CV and CC to Local when analogue remote control is not in use.

Do not apply external voltages to these terminals.
Remote On/Off (XPF 60-20A only)
A switch closure or logic low between connections Rem Off and COMmon will turn off the output.
Warning! COM is referenced to the output control circuit and will be within ~1V of the
positive output potential.
