Communication - Eaton STS 16 Installation And User Manual

Installation

Communication

Use of the communications ports on the
STS module is optional and not required
for correct operation of the module.
STS is equipped as standard with a Basic
communications port for incoming data
from both sources S1 and S2 (both UPSs
must have a free Basic port), as well as
with an STS COM communications port.
Basic communication
For a High Availability Pack configuration,
the Basic STS communications port
receives the data from both UPS sources
S1 and S2. To activate the port, it is
necessary to connect the UPS S1 and
UPS S2 communications ports on the
module to the Basic communications
ports on the UPSs S1 and S2, using the
cables supplied with STS (see figure 7).
The Basic port of the STS always
forwards the status information provided
by the Basic port of the UPS currently
supplying the equipment.
