External Control Connector pin
3.7.6 Multiple load connections with distribution terminals
If remotely located output distribution terminals are used, the power supply output terminals should be
connected to the distribution terminals by a pair of twisted or shielded wires. Each load should be
separately connected to the remote distribution terminals. If Remote Sensing is required, the sensing
wires should be connected to the distribution terminals or at the most critical load.
3.7.7 Grounding outputs
Either the positive or negative output terminals can be grounded. To avoid noise problems caused by
common-mode current flowing from the load to ground, it is recommended to ground the output
terminal as close as possible to the power supply output.
Always use two wires to connect the load to the power supply regardless of how the system is
grounded.
The maximum potential (including output voltage) that either output terminal
is from ground, must not exceed the specified voltage on the front panel.

The External Control Connector signals are connected to the
negative output terminal. If the negative output terminal is
floated with respect to chassis ground , those signals will also
float at the same potential. Use appropriate safety measures
to prevent a shock hazard.
