The UPS start up sequence begins.
• If Auto Bypass is enabled (factory default), the critical load is immediately supplied by the bypass
source, in Bypass mode, until the inverter turns on and the UPS transfers to Online mode. Bypass only
comes on after DC Link is pre-charged. The status on the UPS control panel indicates the UPS is in
Bypass mode. If Auto Bypass is not enabled, the UPS output remains off until the UPS transfers to
Online mode
Every battery cabinet must have a UVR-type DC circuit breaker with an auxiliary contact. Failure to use this type
of circuit breaker may cause severe damage to the UPS and create a personnel hazard. Note that all battery
cabinets provided by the UPS manufacturer have this circuit breaker as a standard feature.
NOTE Do not close battery breaker until pre-charge is complete (i.e. Bypass Mode or Online
Mode has been achieved).
NOTE If "Batteries Disconnected" and/or "Battery Breaker Open" alarms are present, close the
battery breaker.
• The rectifier and inverter turn on. The inverter continues to ramp up to full voltage.
• When the inverter reaches full voltage, the static switch turns off (if auto bypass enabled). Power is
now supplied to the critical load in Online mode. It takes approximately three minutes for the UPS to
achieve Online mode.
• The UPS status indicates Online on the UPS Status area section of the screen. The UPM status
indicates Active on the Overview Screen (see Figure 64).
9. Close the battery breaker. The message “Request close external battery breaker?” appears.
To activate or enable/disable any of the UPS operational modes, follow the online screen prompts.
To obtain any system information, follow the on screen prompts to get to the proper screen. The operator
cannot inadvertently cause a system dump or disconnect unless they override a warning pop-up. Value or
information screens DO NOT affect system operation.

A UPS emergency power-off is initiated by the REPO pushbutton switch. In an emergency, you can use this
switch to control the UPS output.
The REPO switch de-energizes the critical load and powers down the UPSs immediately, without asking for
verification.
The UPS, including Bypass, remains off until restarted.
