If using a split-bypass configuration, remove the factory-installed jumpers between the rectifier input and bypass input busbars, then connect the independent bypass source. For contractors and site engineers, this section provides:
Residual DC voltage remains in the internal capacitor banks even after disconnecting AC utility power. Always verify the DC bus drops below 5V before servicing. For contractors and site engineers
Verify utility frequency stability; check bypass input fuses. High ambient room temperature or faulty battery cell.
Requires inter-unit cables and configuring each unit’s parallel address (0-5). Unit 0 is master. Set DIP switches per Section 5.4. Do not hot-swap parallel cables.
