4.2 Wiring for parallel signal cable
Parallel signal cable connection diagram:
It is recommended to lock the ‘parallel cable’ (as below) for preventing the parallel ports
suffering an unexpected pulling-force and causing the parallel system fault.
4.3 Parallel system Operation:
1.
Turn on the input breakers for the parallel UPS.
2.
Pressing button continuously for more than 1 second for one UPS of the system,
then the system will start to turn on and enter line mode.
3.
Regulate the output voltage of the each UPS separately, and check if the output
voltage difference between the two ups is less than 0.5V. If the difference is more
than 0.5V, the UPS need to be regulated.
4.
If the difference output voltage is less than 0.5V, turn off the input breakers to let
UPS shut down. Then switch on the output breakers for the two UPS.
5.
Turn on the input breakers for the parallel UPS. Pressing button continuously
for more than 1 second for one UPS of the system, then the system will start to turn
on and enter line mode and the system will work normally in parallel.
