Precautions for Correct Use
•
Installation and Storage Sites
Install and store the product in a location that meets
the following conditions:
•
Surrounding temperature of 0 to +50°C
(-20 to + 65°C in storage)
• No rapid changes in temperature (place where dew does not
form)
•
Relative humidity of between 35 to 85 %
• No presence of corrosive or flammable gases
• Place free of dust, salts and iron particles
• Place free of vibration and shock
• Place out of direct sunlight
• Place where it will not come into contact with water, oils or
chemicals
•
Orientation of Product
To improve heat dissipation, install the product in the
following orientation only.
•
Ambient Temperature
• Maintain a minimum clearance of 50 mm above and below
the controller to improve air circulation. A minimum clearance
of 10 mm between other devices must also be maintained on
the right and left sides of the product. However, if the adjacent
devices do not generate heat, provide at least 50 mm of
clearance from the top of the Controller. For the clearance at
the bottom and sides, follow the mounting method.
• Do not install the product immediately above significant
heat sources, such as heaters, transformers, or
large-capacity resistors.
• Do not let the ambient temperature exceed 50 °C (122 °F).
• Provide a forced-air fan cooling or air conditioning if the
ambient temperature is near 50 °C (122 °F) so that the
ambient temperature never exceeds 50 °C (122 °F).
Do not install in this orientation.
Do not install in this orientation.
•
Box type
•
LCD integrated type
To reserve ventilation path,
the feet must be mounted
to the side panel that is
positioned at the base.
•
Ground
• The FZ controller power circuit is not insulated from its internal circuit.
• When grounding the 24 V DC power supply’s positive terminal, do not ground the FZ controller’s FG terminal or the PLC’s FG
terminal.
Since the PC’s shell and the SG (0V) are connected inside the PC, current would run through the route shown in the figure below
and cause burnout.
• As in the case with a PC, you can safely ground the FZ controller’s FG terminal without a problem when there is no possibility that
the SG (0V) and the FG will short-circuit. For information about the PLC wiring, check the specifications of your PLC before wiring.
• Be sure to use a pedestal when connecting a camera to the FZ controller.
As the shell of the camera is the SG (0V), it can cause short-circuiting between the SG (0V) and the FG if a pedestal is not used.
• To avoid receiving an electric shock when grounding a positive terminal, do not touch the SG (0V) (camera, power supply
terminal).
• When mounting a box-shaped controller (FZ3-35_-10/FZ3-H35_-10/FZ3-75_-10/FZ3-H75_-10/FZ3-95_-10/FZ3-H95_-10/FZD-
55_-10) at its base, it will short-circuit to the FG of your device since the bottom surface is connected to the SG (0V). In order to
avoid this, we provide insulating spacers. Please consult your OMRON representative for information.
