2.1 Mounting and other Mechanical Instructions

2.1.1 Mechanical Characteristics

2.1.2 Mounting instructions

The VinciX-48V-BMS Module is supplied as an assembled Printed Circuit Board (PCB) without any enclosure. To maintain safe operating conditions, it is recommended to mount the PCB in an enclosed metal enclosure and leave approximately 10mm space between the PCB and the metal enclosure on both the top and bottom sides. The board outline drawing is shown in the figure below. There are 5 mounting holes of 4.3mm diameter, and the use of M3 screws to install the board is mandatory.
