Maintenance
Do not connect or disconnect Host and GP unit communication cables while the GP is turned ON.
Do not replace the GP unit’s battery yourself. The GP uses a lithium battery for backing up its internal
clock data and the battery may explode if it is replaced incorrectly. When replacement is required, please
contact your local GP distributor.
To prevent a GP unit malfunction due to excessive noise, isolate all GP input/output signal lines from all
power wiring or power cables via a separate wiring duct.
Be sure all cable connectors are securely attached to the GP unit. A loose connection may cause incorrect
input or output signals.
Be sure to ground the GP unit’s FG wire separately from other equipment FG lines. Also, be sure to use a
grounding resistance of 100. or less and a 2mm

[0.0062inch

] or thicker wire, or your country’s applicable
standard. Otherwise, electric shock or malfunctions may result.
Be sure to use only the designated torque to tighten the GP unit’s terminal block screws. If these screws
are not tightened firmly, it may cause a short-circuit, fire or incorrect unit operation.
Be sure that metal particles and wiring debris do not fall inside the GP unit. They can cause a fire, mal-
function or incorrect unit operation.
Be sure to read the GP unit’s manual carefully before performing program changes, entering forced out-
put, or using the RUN, STOP, or PAUSE commands while the GP is operating. Mistakes made when using
these items can cause machine accidents or damage.
Be sure the electricity is turned OFF before attaching or detaching an I/O unit. If the electricity is ON when
an I/O unit is attached or detached, damage or malfunction to the I/O unit may occur.
Be sure to turn the GP unit’s CF Card ACCESS switch OFF and confirm that the ACCESS lamp is not lit
prior to inserting or removing a CF Card. Otherwise, CF Card internal data may be damaged or lost.
Do not reset or turn the GP OFF, or insert or remove the CF Card while the GP unit’s CF Card is being
accessed. Create special application screens to perform operations like turning power OFF, resetting the
GP or inserting or removing the CF Card.
