To start the UPS system:
1. Close all Module Output Breakers (MOBs).
2. Close the UPS input feeder circuit breaker.
3. If dual feed, close the UPS bypass feeder circuit breaker.
4. If IBCs are installed, close the battery breakers.
5. Observe the UPS control panel display becoming active, indicating logic power.
6. Verify no alarms are active.
7. Tap the CONTROLS tab on the main menu navigation bar. The System Control screen is displayed.
8. Tap the GO ONLINE button.
9. If requested, enter the Level 1 password. Default password is 1111.
The rectifier and inverter turn on. The inverter continues to ramp up to full voltage.
Once the inverter reaches full voltage, all UPS inverter switchgear close and the static switches turn off.
Power is now supplied to the critical load in dual conversion mode from all UPSs. It takes approximately
one minute for the UPSs to achieve the dual conversion mode.
If an Integrated Battery Cabinet (IBC) is installed, refer to the Eaton 93PM Integrated
Battery Cabinet Installation Manual-Large and Large High Rate or the Blank, listed in
Chapter 1 Introduction, For More Information section, for IBC battery
breaker location.
If an Sidecar Integrated Accessory Cabinet-Bypass (SIAC-B) is installed, refer to the
Eaton 93PM Sidecar Integrated Accessory Cabinet-Bypass Installation and Operation (50
kW and 100 kW SIAC-B) Manual, listed in Chapter 1 Introduction, For More
Information section, for operating instructions.
This unit is a four-wire device. The loss of a single input phase or the loss of neutral with
unbalanced four-wire loads will be considered a complete loss of input power and
discharge the battery to provide power to the load. This unit does not utilize an actively
switched neutral. Installations are advised that the loss of neutral may affect four-wire
loads. Please contact Eaton if your supply neutral is switched. (e.g. by a 4-pole ATS
switch)
