Open: [no light] Bypass circuit breaker running mode.
(5)
Digital Input 5: Inverter gets ‘EX_FLT1’ (External FauLT 1) signal from this digital input terminal.
Do not connect to the terminal when the terminal has no need.
Close: [green light] shows ‘External Fault 1’ state. Start fault handling procedure.
Open: [no light] No function.
(6)
Digital Input 6: Inverter gets ‘IN_FLT1’ (INternal FauLT 1) signal from this digital input terminal.
Do not connect to the terminal when the terminal has no need.
Close: [green light] shows ‘Internal Fault 1’ state. Start fault handling procedure.
Open: [no light] No function.
(7)
Digital Input 7: Power source of main controller is dualized in N5000 inverter. AC220V power
source for the controller is monitored through this terminal. Do not connect the power source
to the terminal when the terminal has no need.
Close: [green light] AC220V control power is correctly entering.
Open: [no light] AC220V control power is abnormally entering.

Digital Input 8: Power source of main controller is dualized in N5000 inverter. AC1100V power
source for the controller is monitored through this terminal. Do not connect the power source
[Reference 8]
There are two recommending types of installation for N5000 inverter.
Example of installation
K1, K2, and K3 are circuit breakers.
CASE1)
K1: ON, K2: ON, K3: OFF
Inverter running mode.
K1: * , K2: * , K3: ON
Bypass circuit breaker running mode.
In case of inverter running mode, signal should be sent to the digital input 4
terminal. In case of bypass circuit breaker mode, digital input 4 terminal should be
opened.
CASE2)
Inverter is always operated in inverter running mode. Digital input 4 terminal should
always be closed.
