4.2.4 I/O Signal Line Placement
• Input and output signal lines must be separated from the power control cables for operating circuits.
• If this is not possible, use a shielded cable and connect the shield to the OT unit’s frame.
4.3 CF Card Insertion/Removal
This section describes how to insert and remove a CF Card.
Precautions
When using the unit and a CF Card, follow the precautions below:
• Prior to inserting or removing a CF Card, be sure to turn the unit’s CF Card ACCESS switch OFF and to
confirm that the ACCESS lamp is not lit. If you do not, CF Card internal data may be damaged or lost.
• Check that the CF Card DIP switches setting are appropriate.
• While a CF Card is being accessed, NEVER turn OFF or reset the unit, or insert or remove the CF Card.
Prior to performing these operations, create and use a special unit application screen that will prevent
access to the CF Card.
• Prior to inserting a CF Card, familiarize yourself with the CF Card’s front and rear face orientation, as
well as the CF Card connector’s position. If the CF Card is not correctly positioned when it is inserted into
the unit, the CF Card’s internal data and the unit may be damaged or broken.
• Be sure to use only CF Cards manufactured by Schneider Electric. Performance can be compromised
when using another manufacturer’s CF Card.
Once unit data is lost, it cannot be recovered. Since accidental data loss can occur at any time, be sure to back
up all unit screen and CF Card data regularly.
CAUTION
CORRUPTED CF CARD DATA
• Be sure to follow the instructions given below to prevent the CF Card’s internal data from being
destroyed or a CF Card malfunction from occurring:
• DO NOT bend the CF Card.
• DO NOT drop or strike the CF Card against another object.
• Keep the CF Card dry.
• DO NOT touch the CF Card connectors.
• DO NOT disassemble or modify the CF Card.
Failure to follow these instructions can result in injury or equipment damage.
