Step 8-1
Step 8
For backup connection, 12AWG or 4mm² cable is required to be used. For grid connection,
10AWG or 6mm² cable is required to be used. Please make sure the resistance of cable is
lower than 1 ohm.
b. Insert the conductor into the suitable ferrule acc. to DIN 46228-4 and crimp the contact.
c. Unscrew the swivel nut from the threaded sleeve and thread the swivel nut and threaded
sleeve over the AC cable.
d. Insert the crimped conductors L, N and PE into the corresponding terminals and tighten the
screw with a hex key wrench screw driver (size:2.5, 1.2~2.0 N.m). Ensure that all conductors
are securely in place in the screw terminals on the bush insert.
e. Screw the swivel nut onto the threaded sleeve. This seals the AC connector and provides
strain relief for the AC cable. When doing so, hold the bush insert firmly by the locking cap.
This ensures that the swivel nut can be screwed firmly onto the threaded sleeve.
f. Assembly the plug shell ,adapter as below picture, Push the adapter and Shell by hand until
a “Click” is heard or felt.
g. Plug the AC connector into the jack for the AC connection by hand until a “Click” is heard
or felt.

Step 2. Make the cable and crimp theterminal.
When locking the power grid cable into the external power grid connector, the RST should be
marked on the corresponding cable, because when installing the CT, the three CTs with RST
identification need to be buckled on the RST line of the corresponding identification.
