7. CONNECTIVITY AND COMMUNICATION OPTIONS
7.1. MULTILEVEL COMMUNICATION
MASTERYS BC can manage di erent communication channels simultaneously. It is equipped with standard communication ports
and two slots to host additional optional boards.
This gives MASTERYS BC immediate interfacing and integration fl exibility as soon as the unit is installed, with no need for trained
personnel.
The table below lists the possible connections between the UPS and the external devices.
As each channel is independent, simultaneous connections
can be made to satisfy the di erent levels of signalling and re-
mote monitoring.
For UPS systems connected in parallel: all options
listed in this chapter must only be installed on the
UPS systems in the parallel setup configured as ICM
(see chapter 2.11.1). For further information about
parallel systems please refer to the relevant chapter.
