Remote-EPO
The optional Remote-EPO feature allows external control of all outlets. The toggle switch on the
front panel selects the Remote-EPO mode.
•
OFF
will prevent all outlets from being powered.
•
LOCAL/ON
will enable power to all outlets, unless they are being disabled by the outlet
control bus.
•
REMOTE
will place all outlets under the control of the outlet control bus. The outlet
control bus includes three 3-pin connectors which are wired in parallel. This arrangement
allows multiple PDUs to be connected in a daisy-chain configuration and controlled from
a single control panel. The connectors mounted on the PDU are Amp/TE 1-480304-0, and
the mating connector is Amp/TE 1-480305-0. The 3-pin connectors use two low-voltage
signals as follows:
–
Shorting the ENABLE pin to the RETURN pin with a dry contact will trigger the
Enable signal.
–
Opening the DISABLE pin from the RETURN pin will trigger the Disable signal.
This signal is intended to be operated from a normally-closed contact on a control
switch. Note that the DISABLE pin must be shorted to the RETURN pin to allow the
switched outlets to operate, regardless of the toggle switch positions noted above.
–
Note that the Disable signal has priority, so that if both signals are triggered at the same
time, the net result will be Disable.
