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.
