CAUTION
Do not install the control lines or communication cables together with the main circuit lines or power
cables. Keep a distance of 100 mm or more between them.
Failure to do so may result in malfunction due to noise.
The MELSEC-WS safety controller fulfils the requirements of Class A (industrial applications) in
accordance with the "Interference emission" basic specifications.
The MELSEC-WS safety controller is therefore only suitable for use in an industrial environment and not
for private use.
[Installation Precautions]
CAUTION
Use the MELSEC-WS safety controller in an environment that meets the general specifications in the
user’s manual for the CPU module used. Failure to do so may result in electric shock, fire, malfunction, or
damage to or deterioration of the product.
Latch the module onto the DIN rail. Incorrect mounting may cause malfunction, failure or drop of the
module.
To ensure full electromagnetic compatibility (EMC), the DIN mounting rail has to be connected to
functional earth (FE).
Ensure that the earthling contact is positioned correctly. The earthling spring contact of the module must
contact the DIN rail securely to allow electrical conductivity.
Additionally connect all network cable shields directly at the control cabinet entrance to a common FE
ground line.
Tighten the screw within the specified torque range.
Undertightening can cause drop of the screw, short circuit or malfunction.
Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.
Shut off the external power supply (all phases) used in the system before mounting or removing the
module.
Failure to do so may result in damage to the product.
Do not directly touch any conductive part of the module.
Doing so can cause malfunction or failure of the module.
The MELSEC-WS safety controller is only suitable for mounting in a control cabinet with at least IP 54
degree of protection.
Failure to meet the installation method may cause the module to fail or malfunction due to the deposition
of dust or the adhesion of water.
Make sure that the connection of the Ethernet interface module cannot lead to hazardous
situations during installation.
Ensure that the connection of the Ethernet dedicated cables and power cables cannot lead to a
hazardous situation when implementing the unit on to the MELSEC-WS safety controller and Ethernet
network. Prevent unintended start-up of equipment during connection of a Ethernet interface module.
Failure to do so may cause the system to malfunction.
