2.7.1. REMOTE COMMUNICATION BOARD

Remote communication board is used to allow connection between the UPS and external devices.
The board has a series of voltage free contact terminals (M1) which can be connected to a dedicated
synoptic panel (chap. 2.7.2), acoustic or visual warning devices or remote signaling systems.
One or more remote EPO buttons (chap. 2-7-4) or a remote by-pass switch (chap. 2.7.5) can be connected
via the other two contacts (CN1).
Lastly, it is possible to connect the system to a PC via a DB9 (CN3) connector and use the specific
software (chap. 2.7.3)
