5. Press and hold the On button until you hear the uninterruptible power supply
beep (approximately one second). The Power-on LED stops flashing and the
Load level LEDs display the percentage of load being applied to the
uninterruptible power supply. The uninterruptible power supply is now in Normal
mode and is providing power to the connected devices.
Notes:
1. The batteries charge to 90% capacity in approximately 3 hours. Make sure that
you charge the batteries for 24 hours after installation or long-term storage.
2. If more than two extended battery modules are installed, use an external battery
charger for faster recharge times.
Remote emergency power-off installation
The uninterruptible power supply includes a remote emergency power-off connector
that enables you to turn off power at the uninterruptible power supply output
receptacles from a customer-supplied switch in a remote location.
The remote emergency power-off feature shuts down the connected devices
immediately and does not follow the orderly shutdown procedure initiated by any
power-management software.
Any devices that are operating on battery power are also shut down immediately.
When the remote emergency power-off switch is reset, the connected devices will
not return to battery power until the uninterruptible power supply is restarted
manually.
If the Off button is pressed after the remote emergency power-off is activated, the
uninterruptible power supply remains in Standby mode when restarted until the On
button is pressed.
Notes:
1. The remote emergency power-off function activates when the remote
emergency power-off contacts close.
2. For Europe, the emergency switch requirements are detailed in Harmonized
document HD-384-48 S1, “Electrical Installation of the Buildings, Part 4:
Protection for Safety, Chapter 46: Isolation and Switching.”
To connect a remote emergency power-off switch, complete the following steps:
1. Turn off the uninterruptible power supply and disconnect all external cables and
power cords.
