3.2 Mounting/Dismantling

This chapter describes the mounting of the Ethernet interface module.
Make sure that the connection of the Ethernet interface module cannot
lead to hazardous situations during installation!
Ensure that connecting an Ethernet interface module 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 an Ethernet interface module.
3.2.1

Steps for mounting the modules

The MELSEC-WS safety controller is only suitable for mounting in a
control cabinet with at least IP 54 degree of protection.
While supply voltage is applied, modules must not be plugged to nor be
removed from the MELSEC-WS safety controller.
To ensure full electromagnetic compatibility (EMC), the DIN mounting rail
must be connected to functional earth (FE). Additionally connect all
network cable shields directly at the control cabinet entrance to a common
FE ground line.
 In a MELSEC-WS safety controller, the WS0-CPU0 or WS0-CPU1 module is
positioned at the extreme left.

The two optional network modules follow directly to the right of the CPU module.

Connect further MELSEC-WS safety I/O modules (e.g. WS0-XTIO or WS0-XTDI)
onto the right side of the network modules and any additional safety relay output
modules (WS0-4RO) to the extreme right of the entire MELSEC-WS safety
controller.

Mount the modules in accordance with EN 50274.

The modules are located in a 22.5 mm wide modular system for 35 mm DIN rails
according to EN 60715.

Ensure that suitable ESD protective measures are taken during mounting.
Otherwise the FLEXBUS+ backplane bus may be damaged.
 The connection between the modules is effected by means of the plug
connection integrated in the housing. Take into account that, when replacing a
module, the MELSEC-WS modules have to be pushed approx. 10 mm apart
before the corresponding module can be removed from the DIN rail.

Take suitable measures to ensure that foreign matter does not penetrate the
connector openings, in particular that of the memory plug.
