The parallel wiring operation of IST7 series (10kVA-40kVA) is the same but the parallel port position of
IST7 series (30kVA-40kVA) is different with IST710, above we take IST710 as an example to illustrate.
When the battery pack is shared by UPS in the parallel system, please make sure that all battery
parameters of each UPS are consistent, such as battery capacity, battery number, charging voltage and
charging current.
