5Preparatory Work
5.1Installation Instructions
a) Before installation, ensure that BCU manual switch is in disconnected state.
b) The battery shall be installed in a place away from heat source and avoid sparks. The safety distance is greater than 0.5m.
c) The connecting cables for installing batteries shall be as short as possible, to prevent too big voltage drop of the line
d) Batteries of different capacity, different P/N or from different manufacturers cannot be connected.
e) After installation, ensure the anode and cathode of BCU and inverter are connected correctly.
f) The installation place shall be on a horizontal ground, without accumulated water.
