6.2.2 Preparation for Mounting on a Base
After the rack is removed to the installation position of BESS (battery energy storage system) with a forklift
or a tool. Fine adjust the rack and remove it to the designed position, open the internal door of rack, use
M10 or M12 screw to fix the rack.
When the rack needs to be fixed on the steel channel, Φ14 holes can be made in the steel channel. Fix the
rack to the steel channel with screws.
When the rack is fixed to the concrete floor, make holes on the floor and fix the rack to the concrete floor
with expansion screws.
For the detailed mounting on a base, please seen the Installation Manual.
6.3 Electrical Connections
6.3.1 Input requirement
DC-DC 400KW :The PV DC voltage of the cabinet must be within its required input range
，
Otherwise, the DC-DC cabinet will not work. When users configure the number of series of photovoltaic
panels, the maximum input voltage and the minimum input voltage of the module should be fully
considered. Specifically can consult the company's technical service personnel.
The battery system used with the DC-DC cabinet should be equipped with a DC switch and the
charge/discharge voltage should be between input voltage ranges. When the DC-DC cabinet is
connected to an external battery pack, make sure the DC switch is disconnected.
