How to use
Install the UPS in accordance with local electrical regulations and the manufacturer's installation instructions, mounting it in a dry, ventilated environment near the protected equipment. Connect the three-phase supply and the output feeders to the intended distribution circuits, ensuring correct phase sequence and secure terminations.

Usage recommendations
Place the UPS in a cool, dust-free location with sufficient clearance for ventilation and service access.
