AC Utility Line Connection
Connect the AC Utility Line to the power bars of the ATA units, and be sure to divide correctly LINE, NEUTRAL and
EARTH connections. 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.
