DC CIRCUIT SECTIONING
WeCo recommends the installation of a bipolar disconnector for direct current interposed between the battery or several
batteries and inverters.
In some countries it is mandatory, so it is not possible in this manual to give detailed indications to define the type and standard
of this device.
It is required that the installer and the design technician work to verify the local regulations and the sizing of the disconnector to
be used according to the power of the inverter.
In case of need it is still possible to contact WeCo by writing to service@wecobatteries.com
PRE-CHARGE CIRCUIT AND START-UP PRECAUTIONS
The batteries are equipped with a pre-charge circuit to protect the power circuit of the inverter.
During the ignition phase of the batteries the disconnectors installed between the battery and the inverter must be closed, otherwise the
pre-charging function will be ineffective in the open circuit.
The inverter and batteries may be damaged if the disconnectors are closed after the batteries are turned on.
