General Safety Precautions
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, malfunction
or incorrect unit operation.
When the product is disposed of, it should be done so according to your country’s regulations for similar
types of industrial waste.
Do not press on the GP unit’s display with excessive force or with a hard object, since it can damage the
display. Also, do not press on the touch panel with a pointed object, such as the tip of a mechanical pencil
or a screwdriver, since doing so can damage the touch panel.
Do not install the GP where the ambient temperature exceeds the specified range. Doing so may cause a
unit malfunction.
To prevent abnormally high temperatures from occurring inside the GP, do not restrict or block the GP
unit’s rear-face ventilation slots.
Do not operate the GP in areas where large, sudden temperature changes can occur. These changes can
cause condensation to form inside the GP, possibly causing it to malfunction.
Do not allow water, liquids or metal fragments to enter inside the GP unit’s case, since they can cause
either a malfunction or an electric shock. The allowable pollution degree is 2.
