Operation
Start-Up
• VERIFY that all connections to the UPS are correct.
• Verify that either the 3-Phase AC source or the DC source (or both) are present and within range.
If the AC INPUT source or the DC source are active and within range, the color of the LED above
the “ON/OFF” switch will be amber. The amber light indicates that the UPS is in standby mode
and ready to be turn “ON”. The battery pack LEDs will also be appropriately illuminated.
• Momentarily push the “ON/OFF” switch on the front panel of the UPS upward. The switch
can then be released and it will return to its normal (neutral) position.
• The UPS will immediately enable its outputs (assuming there is no fault condition). The color
of the LED above the “ON/OFF” switch will switch from amber to green. The LEDs on the
battery pack will indicate the amount of power being delivered to the load. LEDs on the front
panel will also indicate which source is currently in use.
Note: If no input power sources are available or within the required range, the UPS can still be
turned “ON”. The UPS will draw power from the internal battery for as long as the battery has
charge. A battery startup procedure is also referred as a “COLD START” in the industry. If no
input source is available other than the battery pack, the LEDs above the “ON/OFF” switch and
the battery pack LEDs will be initially “OFF”. When the “ON/OFF” switch is pushed to the “ON”
position, all of these LEDs will be appropriately illuminated.
Shut-Down
• Shut down the equipment connected to the UPS.
• Push the “ON/OFF” switch on the front panel of the UPS downward and hold it in this
position for more than 1 second. The color of the LED above the “ON/OFF” switch will
switch from green to amber (if one or both input power sources are present) or it will turn
“OFF” (if no power sources are present). The switch can then be released to return to its
normal position.
• The UPS will disable all outputs and proceed to shut down.
• The battery pack LEDs will either be appropriately illuminated (if one or both input power
sources are present) or they will be “OFF” (if no power sources are present).
• It is not necessary to move the AC SWITCH on the rear panel of the UPS to the “OFF”
position.
