RPO Installation
Installation of the RPO function must be carried out in compliance with applicable regulations. The cable is not
included.
In order to fully de-energize devices and the Eaton 9135 UPS with the RPO port, it is necessary to:
l
Use a two-position switch (normally-open or normally-closed contact and held more than one second). See
Figure 18.
l
Connect this RPO switch to a device that trips all breaker(s) located upstream
(NOTE 1)
and downstream
(NOTE 2)
from the Eaton 9135 UPS. This can be achieved by means of a shunt trip.
