ATTENTION: for safety and efficiency it is recommended to use always cables with the
cross section equal or thicker than the specified one into the previous table.
In order to have good heat dissipation, the power cables MUST come into the cabinet
from top of the cabinet.
Installer has to consider the max. Power when considering future extension.
We recommend to use dedicate AC Input/Output power Lines for the UPS.
Connect the GROUND wire first when making wire connection. Disconnect the GROUND
wire last when making wire disconnection.
