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 Powerware 9135 with the
RPO port, it is necessary to:
S Use a two−position switch (normally−open or normally−closed contact
and held more than one second).
S Connect this RPO switch to a device that trips all breaker(s) located
upstream
(1)
and downstream
(2)
the Powerware 9135 UPS. This can
be achieved by means of a shunt trip:
−
(1)
If not, the output devices could be powered again through static
switch when the two−position switch is released.
−
(2)
If not, the output devices will remain powered several seconds
after the RPO activation.
NOTE The internal batteries will remain connected to the power module after RPO
activation.
