6.1 Installation Notes
1. This unit must be installed by qualified personnel in
accordance with the locally applicable electrical
regulations.
2. The PROTECT 1.M uses fans for cooling, which
means sufficient ventilation must be provided at the
installation location (see also chapter 6.2:
Installation area).
3. A battery system with a nominal DC voltage of 120
Vdc is required as the external battery for the
PROTECT 1.M. The battery capacity and the battery
pack can be selected according to the user's
requirements. As an option, appropriately
preconfigurations with a wide range of capacity
values can be purchased directly from AEG Power
Solutions.
4. Connection diagram: The PROTECT 1.M has two
input modes: A single-phase input and a three-

mode and selects the corresponding operating
mode automatically.
