CAUTION
•
Securely connect the connector to the module.
•
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.
•
Wire the module correctly after confirming the type of the connected interface. If the cable is
connected to a different interface or wired incorrectly, it may cause a fire or breakdown.
•
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. If the cable is pulled while being connected to the
module, it may damage the module and/or cable or make cable contact improper, causing a
malfunction.
•
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.
[Setup and Maintenance Precautions]

DANGER
•
Do not touch the terminals while the power is on. Doing so may cause electric shocks or
malfunctions.
•
Before cleaning the module or retightening the module mounting screws, make sure to shut off
all phases of the external power supply used by the system. Failure to do so may cause the
module to electric shocks, breakdown or malfunction. If the screws are loose, it may cause the
module to short-circuit, malfunction or fall off. If the screws are tightened excessively, it may
damage the screws and cause the module to short circuit, malfunction or fall off.
