1.7.5. Maintenance Bypass Mode
NOTE: 5-kVA to 10-kVA models include an MCB to switch the load to bypass. On 16-kVA to 20-kVA models, a dry
contact may be used to trigger maintenance bypass.
Used when the UPS requires maintenance or repair, Maintenance-bypass mode powers the connected equipment
with utility power while electrically isolating the internal UPS components.
NOTICE
Risk of power interruption. Can damage the connected equipment.
If utility power fails or if its quality is out of range while the UPS is in Maintenance Bypass Mode, the UPS may shut
down without notice and shut-o output power to the load.
NOTE: The UPS has no user-serviceable parts. If the UPS malfunctions and requires service, visit https://www.
vertiv.com/support/ or contact your local Vertiv representative.
