Connect the Input LINE phase of the first ATA to the phase L1 of AC Three Phases Utility; connect the Input LINE
phase of the second ATA to the phase L2; then connect the Input LINE phase of the third ATA to the phase L3.
Connect the Input NEUTRAL phase of each ATA units and the NEUTRAL of AC Three Phases Utility to the NEUTRAL
power bar. Connect the EARTH of each ATA unit to the EARTH bar. For safety we recommend to install a protection
device (fuse) on the Input LINE connection of each ATA units and a protection device (fuse) on the NEUTRAL
connection of the system. Refer to the diagram below.
ATTENTION: only the input LINE connection of each ATA are to be placed under a protection
system. You can not install the security systems on the input NEUTRAL connection of each ATA.
The input NEUTRAL connections are placed in common on the NEUTRAL bar. The protection of
the input NEUTRAL line must be placed between the power supply and the NEUTRAL bar.
ATTENTION: be sure that the length of all the power cables is as similar as possible for each
ATA, so as to ensure a right distribution of the absorbed current.
The following table shows the recommended size for wires.
