New installation lithium-ion SmartUPS will not start on battery before connecting utility.

Issue:

When you first connect the battery, you need to connect the UPS to utility power before turning it on.

Product Line:

Smart-UPS

Environment:

SMTL2200RM2UC, SMTL2200RM2UCNC, SMTL3000RM2UC, SMTL3000RM2UCNC - All Serial Numbers

Cause:
The Lithium-Ion battery needs to wake-up the first time by applying AC input power to the UPS, before the UPS can power up on battery (“Cold-Start”)

Resolution:

Connect the UPS to AC power to start up. After the battery is powered up for the first time, the UPS can be cold-started (power up on battery) from then on.
