In addition to the "LINE" and "BYPASS" LEDs the "LOAD" LED is now
illuminated. After a few seconds the "INVERTER" LED is illuminated and
the "BYPASS" LED is extinguished. The UPS is now in ON-LINE operation.
ALL LinearPlus/RM: Repeat the UPS start-up procedure on the second and
on third UPS, if present. At this point all the bypass indicators are
extinguished. All inverter indicators illuminate indicating that all parallel UPS
inverters are running, and ready to supply the load.
Fifth step
Connect the load to the UPS output distribution and each UPS LCD display
(LinearPlus) or LED display (LinearPlusRM) indicates the same load value.
The load is spread evenly across all the UPS.
