Hi,
Error code 154 indicates an internal communications fault. To resolve turn the UPS off, brain dead the unit, then restart.
To brain dead
1) Turn off and unplug UPS from wall 2) Disconnect Battery 3) You may hear an audible "click" from the UPS. 4) Reconnect battery, plug unit back in the wall, and turn UPS back on
