Installation and Maintenance Requirements
Mount in a standard equipment rack using 1.0–2.0 mm cold-rolled steel rack frames. Pair with a CC/CV smart charger without balancing hardware. Commission by securing the battery, connecting charger and interconnect cabling, and verifying RS485/CAN telemetry. A 1-foot RS485 cable and parallel cabling are included. Perform an annual visual inspection of bus bars and firmware telemetry review; no calibration or electrolyte servicing is required.
Warranty and Service Information
Includes a 10-year limited manufacturer defect warranty, direct replacement parts distribution, and lifetime technical engineering support.
