RELAY BOARD
The relay board is an interface system with the user on which it is possible to know the status of
the UPS via eight deviators controlled by the system, one of which standard and the other seven
optional. These contacts are normally used for turning on the acoustic and visual signalling systems,
depending on specific events. The types of relays used allow for connecting the users in operation
up to 250V with alternate current, with a maximum input of 10A.
An alarm can be associated with each relay (see table B1), otherwise the standard setting can be
maintained. In the event of having to modify the alarm/relay match-up please contact a technician.
The position of this board will change according to the model chosen, however once removed,
the second access will always be visible and accessible to the user.
