Wiring
Use tube-type pre-insulated terminals and cables with appropriate wire diameters for
terminal wiring.
Cable production steps:
Strip the cable insulation layer, and the size of the exposed copper tube depends
on the size of the pre-insulated terminal.
Insert the conductor part of the cable into the tube-type pre-insulated terminal
and crimp it with a crimping tool.
Cable access steps:
Press the spring of the connection terminal and insert the cable with the tube-
type pre-insulated terminal into the port.
Loosen the spring of the terminal block, gently pull the cable, and check whether
the cable is firmly connected.
