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

■ 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.
