UPS Operation
Using the PowerPass
The PowerPass provides a high level of reliability with surge suppression and continuous online power for your equipment. It also maximizes uptime by providing a second source of power and surge protection. The PowerPass allows you to:
:Replace or upgrade the UPS without losing power to your equipment
:Provide surge protection if the UPS is not present
:Provide extra surge protection when the UPS is present
:Increase the number of output receptacles
:Protect a laser printer against power surges without overloading the UPS
This Maintenance Bypass feature is useful when replacing the UPS for maintenance or upgrades. Figure 11 shows the operation of the UPS with the PowerPass.
