The UPS cabinet must be permanently bonded to the facility's safety grounding system before applying any input voltage.

It wasn't a software glitch. It was suffocating. Maintenance

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.

: Standard configurations include 415V AC 3-phase input and 240V AC single-phase output.
