Precautions for Safe Use 3
• Locations subject to water, oil, or chemicals
• Locations subject to shock or vibration
Take appropriate and sufficient measures when installing systems in the fol-
lowing locations. Inappropriate and insufficient measures may result in mal-
function.
• Locations subject to static electricity or other forms of noise
• Locations subject to strong electromagnetic fields
• Locations subject to possible exposure to radioactivity
• Locations close to power supplies
■
Installation and Mounting
• Use the EtherNet/IP-DeviceNet Router within an enclosure with IP54 pro-
tection or higher according to IEC/EN 60529.
• Use DIN rail (TH35-7.5/TH35-15 according to IEC 60715) to install the
EtherNet/IP-DeviceNet Router into the control panel. Mount the EtherNet/
IP-DeviceNet Router to the DIN rail using PFP-M End Plates (not included
with the EtherNet/IP-DeviceNet Router) to prevent it falling off the DIN rail
because of vibration.
• Space must be provided around the EtherNet/IP-DeviceNet Router, at
least 5 mm from its side and at least 50 mm from its top and bottom sur-
faces, for ventilation and wiring.
■ Installation and Wiring
• Use the following to wire external I/O devices to the EtherNet/IP-
DeviceNet Router.
• Disconnect the EtherNet/IP-DeviceNet Router from the power supply
before starting wiring.
• Properly apply the specified voltage to the EtherNet/IP-DeviceNet Router
inputs. Applying an inappropriate DC voltage or any AC voltage may inter-
fere with functionality, may reduce safety, or may cause the EtherNet/IP-
DeviceNet Router to be damaged or burnt.
• Be sure to separate the communications cables and I/O cables from near
high-voltage/high-current lines.
• Be cautious not to get your fingers caught when attaching connectors to
the plugs on the EtherNet/IP-DeviceNet Router.
• Tighten the DeviceNet connector screws correctly (0.25 to 0.3 N·m).
• Incorrect wiring may lead to loss of safety functions. Wire conductors cor-
rectly and verify the operation of the EtherNet/IP-DeviceNet Router before
using the system in which the EtherNet/IP-DeviceNet Router is incorpo-
rated.
• After wiring is completed, be sure to remove label for wire clipping preven-
tion on the EtherNet/IP-DeviceNet Router to enable heat to escape or
proper cooling.
■ Power Supply Selection
Use a DC power supply satisfying the following requirements.
Solid wire
0.2 to 2.5 mm
2
(AWG 24 to AWG 12)
Stranded (flexi-
ble) wire
0.34 to 1.5 mm
2
(AWG 22 to AWG 16)
Stranded wires should be prepared by attaching insulated bar
terminals (DIN 46228-4 standard compatible) to the ends before
connecting them.
