Safety Precautions
!CAUTION
■Precautions for Safe Use
•Do not use or store the product in the following locations.
•Locations subject to direct radiant heat from heating equipment
•Locations where the product may come into contact with water,
oil, or salt water
•Locations subject to direct sunlight
•Locations where dust or corrosive gases (in particular, sulfuric
or ammonia gas) are present
•Locations subject to extreme temperature changes
•Locations where icing or condensation may occur
•Locations subject to excessive shocks or vibration
•Locations subject to temperatures or humidity outside the
specified range
•Locations outdoors or exposed to wind or rain
•Locations subject to static electricity or noise
•Do not use the product in locations subject to temperatures outside
the specified ranges or in locations subject to condensation. If the
product is installed in a panel, be sure that the temperature around
the product (not the temperature around the panel) does not go
outside the specified range. The life of components is dependent
on the temperature. The life of components shortens when the
temperature rises, and it lengthens when the temperature falls. The
life of components can be lengthened by lowering the temperature
inside the product.
•Do not install the product near devices generating strong high
frequency waves or surges. When using a noise filter, check the
voltage and current and install it as close to the product as
possible.
•Do not touch terminals or perform wiring while power is supplied to
the product. Doing so may result in injury or malfunction.
•Do not touch the terminals while power is being supplied. Doing so
may result in product failure or malfunction.
•When tightening the terminals or connecting connectors, support
the product with one hand to prevent it from being pushed out of the
front of the panel.
•Wire to the correct terminal number. Incorrect wiring may result in
damage to or burning of components.
•Be sure power supplies and power lines for control power supply
and inputs have appropriate specifications. Not using power
supplies and power lines with appropriate specifications may result
in malfunction, burning, or electric shock.
•Do not attempt to disassemble, repair, or modify the product. Doing
so may occasionally result in minor or moderate injury.
•Do not allow pieces of metal, wire clippings, or fine metallic
shavings or filings to enter the product. Doing so may occasionally
result in fire or product failure.
•For DC input, use an SELV power supply with overcurrent
protection. Specifically, use an SELV power supply with double or
reinforced insulation between input and output, and an output
voltage of 30 Vrms with 42.2 V peak or 60 VDC maximum.
Recommended power supply: S8VS-06024@ (OMRON product)
■Precaution for Correct Use
Wiring
•Do not tighten the power supply terminals with excessive force
when wiring. Doing so may damage the terminals. Tighten each of
them to a torque of 0.29 to 0.49 N·m.
•Do not impose excessive force on the rear panel when tightening
the terminals of the M7F or connecting a connector to the M7F.
•When tightening the terminals of the M7F or connecting a
connector to the M7F, hold the displays by hand, otherwise the
displays may protrude from the case.
Environment
When using the M7F in places with dust, metal powder, or sprayed
oil, be sure to take appropriate measures so that no dust, metal
powder, or sprayed oil will penetrate the interior of the Display Units.
Mounting
•When panel-mounting, make sure that the side of the case marked
“TOP” is upward.
•When panel-mounting, do not press the central part of the displays,
otherwise the displays may be damaged. Press the flange part.
Connections
•If power will be supplied to the M7F from the PLC's I/O service
power supply, make sure that the current consumption of the M7F
does not exceed the rated capacity of the service power supply.
•It is recommended to supply power to the M7F from a dedicated
DC power supply in order to protect the PLC from being damaged.
•When using a controller other than the PLC or another company's
PLC, be sure to check the terminal arrangement of the connector of
the controller or the PLC. The terminal arrangement of OMRON's
cables incorporating connectors corresponds to that of the PLC.
Removing Color Plate
There is a gap (with a width of approximately 1 mm) between the
case and color plate on the left and right sides. To remove the color
plate, insert a flat-blade screwdriver into either one of the gaps and
move the color plate upwards.
Replacing Unit Plate
•Remove the unit plate with a pair of tweezers.
•Before pasting a unit plate to the plate holder, remove the ground
paper from the unit plate. Paste the unit plate to the plate holder so
that the symbol mark or character(s) of the face plate will be on the
bottom side (i.e., the decimal-point side) of the M7F.
Tighten the screws on the terminal block securely using
the recommended tightening torque of 0.29 to 0.49 N·m.
Loose screws may occasionally cause fire, resulting in
minor or moderate injury, or damage to the equipment.
