Undertightening can cause a short circuit, fire or malfunction.
Overtightening can cause a drop, short circuit or malfunction due to damaged screws or
module.

Do not touch the conductors and electronic parts of the module directly.
Doing so can cause a malfunction or failure.
Fit the external device connection connector and peripheral device connection connector
securely into the connectors of the module, and confirm that they click.
Incorrect fitting can result in poor contact, causing false input or false output.
When the drive unit and peripheral device are not connected, always mount the connector
covers. Failure to do so can cause a malfunction.
