2. Installation
1 - Check that the battery circuit breaker (1)
of each EXB is OFF ("0" position).
Start the following operations from the
lowest level:
2 - Connect the battery cable (2) to the UPS
battery power connector (3) and the other
end of the battery cable to the EXB battery
power connector (4).
3 - Connect the battery detection cable (5)
to the UPS battery detection connector (6)
and the other end of the battery detection
cable to the EXB battery detection
connector (7).
4 - Connect the inter-EXB battery cable (8)
to the second EXB battery power
connector (9) and the other end of the
battery cable to the second EXB battery
power connector (10) of the above EXB.
5 - Connect the battery detection cable to
the second EXB battery detection
connector (11) and the other end of the
battery detection cable to the second EXB
battery detection connector (12) of the
above EXB.
6 - Repeat operations 2 to 5 to other levels
7 - Close the battery circuit breaker (1) of
each EXB ("I" position).
1 - Connect the equipments to the UPS
using the cables (1).
It is preferable to connect the priority
equipments to the two outlets (3) and the
non priority equipments to the two outlets
(2) that can be programmed in pairs.
Connect any high-power devices to the
16 A outlet (4).
To program shutdown of outlets (2) during
operation on battery power and thus
optimise the available backup time, the
EATON communication software is
required.
2 - Fit the connection securing system (5)
that prevents the plugs from being pulled
out accidentally.
