➢ Strip the cable insulation, the exposed copper part depends on the size of the tube-
type pre-insulated terminal.
➢ Pass the conductor part of the cable into the tubular pre-insulated terminal and
crimp it with a crimping pliers.
→Wire cable connection steps:
➢ Press the spring of the terminal to insert the cable with the tubular pre-insulated
terminal into the port.
➢ Loosen the spring of the terminal, pull the cable lightly to check whether the cable
is firmly connected.
Matters need attention
➢ When wiring the terminal cables, avoid being bundled with cables with strong
interference signals, such as power lines, and must be routed separately.
➢ In the case of serious on-site electromagnetic interference, shielded cables should
be used to improve the anti-interference ability.
➢ It is not recommended to use the same power supply for the coupler module and
the expansion sub-module, especially when there is serious on-site electromagnetic
interference, different power supplies must be used and do not share the same
ground.
