Installation Precautions - Mitsubishi Electric CC-Link User Manual

[Installation Precautions]

• Do not directly touch the CC-Link embedded I/O adapter's conductive parts.
Doing so could cause malfunction or failure in the CC-Link embedded I/O adapter.
• Securely solder the CC-Link embedded I/O adapter to install it to a user board.
Defective contact could cause malfunction.
[Wiring Precautions]
• Before beginning any installation or wiring work, make sure that all phases of the power supply
have been obstructed from the outside.
Failure to completely shut off the power supply phases may cause electric shock and/or damage
to the adapter.
• Always ground the FG terminal to the protective ground conductor.
Doing so may cause electric shock or malfunction.
• Correctly connect the CC-Link embedded I/O adapter after confirming the rated voltage and pin
numbers of the product.
Failure to do so could make a short circuit with bare solderless terminals.
• When wiring the CC-Link embedded I/O adapter, check the rated voltage and terminal layout
and make sure the wiring is done correctly.
Connecting a power supply that differs from the rated voltage or wiring it incorrectly may cause
fire, failure or malfunction.
• Make sure that there are no foreign substances such as sawdust or wiring debris inside the CC-
Link embedded I/O adapter.
Such debris could cause fire, failure or malfunction.
• Make sure that the communication cable connected to the adapter is kept in the duct or fixed
with cramps.
Failure to do so may cause a damage to the user board or cables due to dangling, shifting or
inadvertent handling of cables, or misoperation because of bad cable contacts.
• Do not grab on the cable when removing the communication cable connected to the adapter.
When removing the cable with a connector, hold the connector on the side that is connected to
the adapter.
When removing the cable without a connector, loose the screws on the side that is connected to
the adapter.
Pulling the cable that is still connected to the adapter may cause a damage to the user board or
cable, or malfunction due to bad cable contacts.
