Fail-safe function
Disconnection of a signal line, instantaneous power failure, or abnormal signal may cause a problem.
For this reason, please adopt a fail-safe function for the entire system by yourself.
To ensure safety, be sure to incorporate the interlock circuit, limit circuit, or the like, in the external cir-
cuit excluding the S-LINK V system circuit.
CAUTION
To connect the S-LINK V gateway controller to your system, be sure to adopt a fail-safe function.
Regarding the fail-safe function, if you have an unclear or doubtful point, please contact our sales division.
Conformity to EC Directives
The S-LINK V gateway controller conforms to various standards. However, to connect the gateway
controller to your system, check that the entire system can conform to various standards.
WARNING
To conform to the EC Directives, the S-LINK V system is tested in accordance with the EMC Directive stan-
dards, such as EN 50081-2 of the EMI standard and IEC 61000-6-2 of the EMS standard. When you incorporate
the S-LINK V system in your machine or equipment, check that the wiring condition conforms to the require-
ments of the EC Directives.
To use the SL-VGU1-C together with the PLC (programmable logic controller) manufactured by Mitsubishi Elec-
tric Corporation and to conform to the requirements of the EMC order, observe the following items.
Install the system while referring to the ‘PLC User’s Manual’ prepared by Mitsubishi Electric Corporation and the
‘CC-Link User’s Manual.’
● Be sure to put the PLC and the SL-VGU1-C in a conductive box.
● Be sure to ground the shielded cable that connects the PLC to the SL-VGU1-C in the 300mm area of the
SL-VGU1-C.
● If the shielding effect is not enough, install a ferrite core.
