3.3.2 Remote Bus Connectors
There are a total of three remote bus connectors two at the front, and one at the rear. All connectors are wired in parallel.
Multiple PDUs can be wired in a daisy-chain fashion to be operated by a single remote panel. It does not matter which
connectors are used for “in” vs. “out” purposes.

3.3.2.1 Remote Bus Connector Wiring
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 remote bus Enable signal.
•
Shorting the Disable pin to the Return pin with a dry contact will trigger the remote bus Disable signal.
•
Note that the Disable signal has priority, so that if both signals are triggered at the same time, the net result will be
Disable.

3.4 Outlet Sequencing Option
The Outlet Sequencing option requires that the remote switching/EPO option be present as well. Note that the remote
option alone does not necessarily include sequencing, but sequencing can be configured at the time of purchase. Refer to
Marway’s Standard Products Catalog for a list of the specific models which include the sequencing option.
With the sequencing option, Group A outlets are powered when the main circuit breaker is turned on, Group B outlets are
powered upon Enable, and Group C outlets are powered about 2 seconds after Group B.
