The secondary circuit wiring for NA1-2000X~6300X with type (3H) intelligent controller and instantaneous under-voltage release The secondary circuit wiring for NA1-2000X~6300X with standard type (M) 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 : communication output
12 ,13 : Signal alarm of load 1 output; 14 ,15 : Signal alarm of load2 output
16 ,17 :Breaking signal output; 18 ,19 :Making signal output
20 : PE line; 21 : N phase input terminal
22 ,23 ,24 : A, B, C three phase power input terminal (note the sequence)(highest-voltage of AC 400V)
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.
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.
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 ~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.

Circuit explanation for signal output:
a. Broken-line parts shall be provided by customers.
# #
b. Terminals 6 ,7 can output NC (normal close) contact if that is required by users.
#
c. Terminal 35 can be directly connected to power (automatic pre-storing energy),
alternatively connect power after connecting NO button (manual-controlled pre-storing energy).
# #
d. The 21 ~24 is only for wiring with function meter display. (Excluding the special wiring)
