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.
