Engineering friendly design

Master Slave 1 Slave 2 Slave 15

• Slave units operate as alternative in cycle duty to realize higher stability, better

reliability and longer lifespan.

• Every time after the all units are turned off or all slave unit are turned off.

Control reliability design

Master Slave Master Slave

• If one slave unit fails, this unit will stop but the others will keep running. If master unit

fails, all the units will stop.

• If master unit’s protection happens, this unit will stop but the others will keep running.

If slave unit’s protection happens, this unit will stop but the others will keep running.

Except PE, P9 protection happens
