[Wiring precautions]
Connectors for external connection must be crimped or pressed with the tool specified by the
manufacturer, or must be correctly soldered.
If the connection is incomplete, it may cause the module to short circuit, catch fire, or malfunction.
Install connectors securely to modules.
Make sure to place the communication and power cables to be connected to the module in a duct or
fasten them using a clamp. If the cables are not placed in a duct or fastened with a clamp, their
positions may be unstable or moved, and they may be pulled inadvertently.
This may damage the module and the cables or cause the module to malfunction because of faulty
cable connections.
When disconnecting the communication and power cables from the module, do not pull the cables
by hand.
When disconnecting a cable with a connector, hold the connector to the module by hand and pull it
out to remove the cable.
When disconnecting a cable connected to a terminal block, loosen the screws on the terminal block
first before removing the cable. If a cable is pulled while being connected to the module, it may
cause the module to malfunction or damage the module and the cable.
Be careful not to let any foreign matter such as wire chips get inside the module. They may cause
fire, as well as breakdowns and malfunctions of the module.
A protective sheet is pasted on the upper part of the module in order to prevent foreign matter such
as wire chips to get inside the module while wiring.
Do not remove this protective sheet during wiring work.
However, be sure to remove the protective sheet before operating the module to allow heat radiation
during operation.
