- The GLC must be used as a built-in component of an end-use
product.
- The GLC should be installed in the front face of a metal panel.
- If the GLC is installed so as to cool itself naturally, be sure to
install it in a vertical panel.
General Wiring Cautions:
- To prevent shocks or malfunctions, the GLC’s FG (earth) wire
should be grounded according to the following:
1) A maximum grounding resistance of 100
Ω
Ω
Ω
Ω
Ω
or less.
2) A grounding wire of 2mm
2
or larger should be used.
- The GLC’s wiring should be checked to confirm both that the
operating voltage and wiring terminal locations are correct. If ei-
ther the voltage or the wiring terminal locations are incorrect, it
can cause a fire or accident.
- Be sure to secure all wiring terminal screws in place with the
designated torque. Screws and terminals that become loose can
cause a short circuit, fire or accident.
- Be sure that metal filings or wiring remnants do not fall inside the
GLC, since they can cause a fire, accident, or malfunction.
GLC Operation and Maintenance Cautions:
- Be sure to read the GLC’s manual and on-line help information
carefully before performing program changes, forced output, or
utilizing the RUN, STOP, PAUSE, Enable I/O and other commands
while the GLC is in operation. Mistakes concerning the use of
these items can cause a machine accident or damage.
- The liquid crystal panel contains a powerful irritant and if for any
reason the panel is damaged and this liquid enters your eye, flush
your eye for 15 minutes with running water and contact a physcian.
- Prior to inserting or removing a CF Card, be sure to turn the GLC'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 dam-
aged or lost.
- Do not turn OFF or reset the GLC while a CF Card is being ac-
cessed or insert or remove the CF Card. Prior to performing these
operations, create and use a special GLC application screen that
will prevent access to the CF Card.
GLC Unit Disposal Cautions:
- Be sure to dispose of the GLC unit in a manner appropriate to
your country’s industrial machinery disposal standards.
