[Wiring Precautions]
● Prevent foreign matter such as dust or wire chips from entering the module.
Such foreign matter can cause a fire, failure, or malfunction.
● A protective film is attached to the top of the module to prevent foreign matter,
such as wire chips, from entering the module during wiring. Do not remove the
film during wiring. Remove it for heat dissipation before system operation.
● When the CC-Link system master/local module is connected to the head
module, use dedicated cables that are specified by the manufacturer. If any
other cable is used, performance of the CC-Link system is not guaranteed.
Also, the maximum overall cable length and the station-to-station cable length
must meet those specified in the MELSEC-L CC-Link System Master/Local
Module User's Manual. If not, normal data communication is not guaranteed.
● Mitsubishi 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 who is
familiar with protection against electric shock.
For wiring methods, refer to the MELSEC-L CPU Module User's Manual
(Hardware Design, Maintenance and Inspection).
Precautions for using high-speed counter modules
● Ground the shield cable on the encoder side (relay box). Always ground the
FG and LG terminals to the protective ground conductor. Failure to do so may
cause malfunction.
Precautions for using CC-Link/LT master module
● For the CC-Link/LT, use the cables specified by the CC-Link Partner
Association. The performance of the CC-Link/LT cannot be assured if any
other cables than the specified are used. For the network wiring, follow the
specifications described in MELSEC-L CC-Link/LT Master Module User's
Manual. Normal data communication is not guaranteed if the wiring is not
conducted according to the specifications.
