[Wiring Precautions]
CAUTION
● Programmable controllers must be installed in control panels. Connect the main power supply to the
power supply module in the control panel through a relay terminal block. Wiring and replacement of a
power supply module must be performed by qualified maintenance personnel with knowledge of
protection against electric shock. For wiring, refer to Page 122 Wiring in this manual.
● For Ethernet cables to be used in the system, select the ones that meet the specifications in the user's
manual for the module used. If not, normal data transmission is not guaranteed.
[Precautions for using channel isolated analog-digital converter modules, channel isolated
digital-analog converter modules, channel isolated RTD input modules, and temperature
control modules]
● Individually ground the shielded cables of the programmable controller with a ground resistance of
100 ohms or less. Failure to do so may result in electric shock or malfunction.
[Precautions for using channel isolated thermocouple input modules]
● Individually ground the shielded cables of the programmable controller with a ground resistance of
100 ohms or less. Failure to do so may result in electric shock or malfunction.
● Do not place the module near a device that generates magnetic noise.
[Precautions for using high-speed counter modules and flexible high-speed I/O control
modules]
● Do not install the control lines or communication cables together with the main circuit lines or power
cables. Keep a distance of 150mm or more between them. Failure to do so may result in malfunction
due to noise.
● Ground the shield cable on the encoder side (relay box) with a ground resistance of 100 ohm or less.
Failure to do so may cause malfunction.
[Precautions for using CC-Link IE Controller Network (when optical fiber cables are used)]
● For optical fiber cables to be used in the system, select the ones that meet the specifications in the
MELSEC iQ-R Ethernet/CC-Link IE User's Manual (Startup). If not, normal data transmission is not
guaranteed.
[Precautions for using CC-Link system master/local modules]
● Use Ver.1.10-compatible CC-Link dedicated cables in a CC-Link system. If not, the performance of
the CC-Link system is not guaranteed. For the station-to-station cable length and the maximum
overall cable length, follow the specifications in the MELSEC iQ-R CC-Link System Master/Local
Module User's Manual (Startup). If not, normal data transmission is not guaranteed.
[Precautions for using redundant function modules]
● For tracking cables to be used in the system, select the ones that meet the specifications in the
MELSEC iQ-R CPU Module User's Manual (Startup). If not, normal data transmission is not
guaranteed.
[Precautions for using AnyWireASLINK master modules]
● Do not apply the 24VDC power before wiring the entire AnyWireASLINK system. If the power is
applied before wiring, normal data transmission is not guaranteed.
● Connect a 24VDC external power supply to the device(s) in an AnyWireASLINK system.
