Error Codes - PROLiNK Master II Series User Manual

3) Turn off the output breaker and disconnect the parallel cable and share the UPS current cable you
want to remove. Now, you can disconnect the UPS from the parallel system.
4) Turn on the input breaker of the remaining UPS and the system will switch to Bypass mode. Set the
maintenance switch from "BPS" to "UPS position and reinstall the maintenance bypass cover.
5) Turn on the rest of the UPS according to the previous section.
Warning: (Only for parallel systems )
●
Before turning on the parallel system to activate the inverter, make sure that all the maintenance
switches of the unit are in the same position.
●
When the parallel system is turned on, please do not operate any unit maintenance switch.
●
Parallel systems do NOT support ECO mode. Therefore, please DO NOT "Enable" ECO mode in any
unit.
