Installation Guidelines

Mount the device vertically on a 35mm DIN rail (EN 60715 35x15/7.5) inside a control cabinet.
Maintain a minimum clearance of 50 mm above and below the unit to facilitate natural convection cooling.
Use a cable cross-section of at least 10 mm² for the 24 V DC input (L+) to safely handle the 40 A load.
Ensure correct polarity when connecting the external battery module to prevent damage to the internal fuse.
Always power down the system before performing wiring or maintenance on the module.
