7.2.3 Communication bus monitoring
PARALLEL RECTIFIER
1-[ M ] 2- S
The second line of this menu gives a general indication regarding the communication between the UPS
units composing the system.

The numbers represent the single UPS units.

The letters M and S stand for MASTER and SLAVE respectively.

The brackets [ ] around a letter indicate that we are working on that specific UPS unit.

A question mark next to a number indicates that that UPS unit is not communicating on the data
bus.
7.2.4 Parallel type
PARALLEL
REx
The string on the second line may have two values, “POWER” or “REx”.

POWER means that the parallel system is so set as to require the presence of all the UPS units
to feed the load.

REx means that the system is redundant and the redundancy index is indicated by
number “X”. For example, in a system composed of 2 UPS units, “RE1” means that
only one of the UPS units is sufficient to feed the load.
