1.4.9 Installing Power Modules and Battery Modules
The number and possible installation positions of the Power Modules and Battery Modules may vary according to
the chosen factory configuration. Thanks to the different mounting depth it’s not possible to install a power module
instead of a battery module and vice versa.
Please install the power modules and Battery modules from bottom to top, so as to avoid cabinet toppling due to high
gravity center.
