The secondary circuit wiring for NA1-2000X~6300X with type (3M) intelligent controller and time-delay under-voltage release The secondary circuit wiring for NA1-2000X~6300X with type (3H) intelligent controller and time-delay under-voltage release
# # # # # # # #
3 ,4 ,5 : Fault trip contact output(4 common terminal); 6 ,7 ,8 ,9 : Auxiliary contact（normal open）
# # # #
10 ~11 : empty; 12 ~19 are the programmable output terminal. The normal products without these terminals,
but if the customer special ordered, the cost extra added.
3M type acquiescence output:
# # # #
12 ,13 : Signal alarm of load 1 output; 14 ,15 : Signal alarm of load2 output
# # # #
16 ,17 : Self-diagnose alarm; 18 ,19 : Fault trip
# # #
20 : PE line; 21 ~24 : Display the voltage of the signal input. The normal products without these terminals,
if the customer special ordered the function meter, the cost extra added.
# # # #
21 : N phase input terminal; 22 ,23 ,24 : A, B, C three phase power input terminal (note the sequence)(Highest-voltage of AC400V)
# #
25 ,26 Connect to the N phase current transformer or the input terminal of the current leakage transformer.
The normal products without these terminals, if the customer special ordered, the cost extra added.
# # # #
27 ,28 : Under-voltage release( C
onnected to the main circuit)
; 29 ,30 : Shunt release
# # # #
31 ,32 : Closing release; 33 ,34 : Energy storage indicator
# # # #
34 ,35 : Energy storage motor; 36 ,37 : Under-voltage time delay release
# #
38 ~51 : Auxiliary contact
Note:
a. Red colored part is to be connected by users
b. When the power system is three phase three wire, directly connect the Un to U2. (If the voltage exceeds 400V,
special explanation when ordered)

1 , 2 : Intelligent controller power input
Note: When the power supply of the intelligent controller
is AC power, the 1 ~2 connects to the AC power directly.
When the power supply is DC power, forbid connecting the
1 ~2 to the DC power directly. Add a DC power supply
module, then the DC power connect to the input terminal
of the DC power supply module, and the 1 ~2 connect to
the output terminal of the DC power supply module,
or else the intelligent controller will be damaged.

ST~DP: DP protocol module. There is no need for the ST-DP protocol module,
if the communication protocol is Modbus-RTV. But when the communication protocol is Profibus-DP,
the ST-DP protocol module is necessary, but the cost extra added.
ST power module IV: power converter (optional components)
ST201: Magnify the signal capacity of the controller. ( optional components)
If the customer special ordered, the cost extra added.
