ABB REACT-3.6-TL Application Note page 5

three connections are required to connect the backup output: Phase, Neutral and Earth, with a cable of a maximum
2
size of 4 mm (the connection of the earth wire is mandatory).
The electrical features of the backup output to be taken into account for the sizing of the line are indicated in the
table below:
BACKUP OUTPUT – Technical Data
Rated AC output Voltage (Vacr)
Maximum output Current (Iac max)
Rated output Frequency (fr)
Maximum Apparent output Power (Sacr)
Maximum output fault current
Maximum AC overcurrent protection
We recommend sizing the conductor by defining the section based on the length of the line in order to limit voltage
dips at the load terminals, and therefore avoid any unwanted disconnection of the utilities connected to the backup
source. In this regard, the following table should be considered as reference:
230 V (1Ø)
13 A
50 Hz
3000 VA
27 A rms (60ms)
16A
