Remote power off
Installation of a Remote power off function must be carried out in compliance with applicable regulations.
In order to fully de-energize devices and EX RT with an RPO port, it is necessary:
- To use a two-position switch (Normally Open or Closed contact should be held more than 1 second to be
taken into account),
- To use battery cabinet(s) EX RT EXB EPO.
- To connect to this RPO switch a device that allows to trip all breaker(s) located upstream
and AC BY PASS as well as downstream
trip.
(1) If not, the output devices will remain powered through the AC BY PASS if RPO switch has been
loosened.
(2) If not, the output devices will remain powered several seconds after the RPO activation.
