3.3 System ground
For system safety, the housing of the battery system can be grounded or equipotential
connected. When the original protective conductor fails, it prevents the ground current from
touching the current, causing personal injury.
The system grounding cable steps are as follows:
(1) Confirm that the battery system is turned off and there is no input.
(2) Connect the ring terminal at one end of the yellow-green ground wire (labeled
CABINET/GND) to the grounding point of the top beam of the cabinet.
(3) The other end passes through the waterproof joint of the cabinet and is connected to
the grounding point of the outer casing of the inverter.
3.4 System wiring
Note: In order to ensure that the lithium battery system can safely and reliably
disconnect from the grid, install a separate single-pole or two-stage circuit breaker as a
protection device (according to local electrical codes) before the grid is connected to the
lithium battery system; Before you need to ensure that the battery module is in the off state;
all external connection cables are routed from the top of the cabinet through the hole
