5.2 Steps for dismantling the modules
Remove the removable terminals with wiring and the end clips.
If there are several modules, slide the modules away from each other
individually in the direction of the arrow until the side plug connection is
separated.
Press the module downwards at the rear (1)) and remove it from the
DIN rail in the direction of the arrow while keeping it pressed down (2)).
6 Electrical installation
De-energize the entire system!
Mettez le système entièrement hors tension !
The system could start up unexpectedly while you are
ATTENTION
connecting the devices.
Le système pourrait être mis en marche par inadvertance
pendant qu'on connecte les dispositifs.
Observe the relevant safety standards!
Observez les normes de sécurité pertinentes!
All safety related parts of the installation (cabling,
connected sensors and actuators, configuration settings,
EDM) must be according to the relevant safety standards
(e.g. IEC 62061 or EN/ISO 13849-1).
Tout matériel ou logiciel ayant des implications de sécurité
(câblage, capteurs et actionneurs à raccorder,
paramétrages de configuration, EDM) doivent être
conformes aux normes de sécurité applicables (par
exemple, IEC 62061 ou EN/ISO 13849-1).
The MELSEC-WS safety controller fulfils the EMC requirements in
accordance with the basic specification IEC 61000-6-2 for industrial use.
Carry out the electrical installation in accordance with EN 60204-1
To ensure full electromagnetic compatibility (EMC), the DIN rail has to
be connected to functional earth (FE).
The voltage supply of the devices must be capable of buffering brief
mains voltage failures of 20ms as specified in IEC 60204-1.
The voltage supply has to fulfil the regulations for extra-low voltages
with safe separation (SELV, PELV) in accordance with IEC 60664 and
EN 50178 (equipment of electrical power installation with electronic
devices).
You must connect all the modules of the MELSEC-WS safety controller,
the connected protective devices as well as the voltage supply/ies with
the same 0VDC (GND).
All connected pick-ups and downstream controllers as well as wiring
and installation have to fulfil the required safety characteristics.
If a module is replaced the correct terminal assignment has to be
guaranteed, for example by labelling or suitable cable routing.
For further information that is to be taken into consideration when the
MELSEC-WS safety controller is used, refer to the "Safety Controller
User's Manual" and "Safety Controller Setting and Monitoring Tool
Operating Manual".
7 Configuration and commissioning
Do not commission without a check by qualified
safety personnel!
Ne pas procéder à la mise en service sans qu'un
ATTENTION
personnel de sécurité qualifié ait effectué un
contrôle.
Before initial commissioning of a system using a
MELSEC-WS safety controller, it must be checked and
released by qualified safety personnel. Document the
result of the safety check.
La première mise en service d'un système utilisant un
contrôleur de sécurité MELSEC-WS ne doit être
effectuée qu'après contrôle et sur autorisation délivrée
par un personnel qualifié. Les résultats du contrôle de
sécurité doivent être dûment documentés et suivis.
The MELSEC-WS safety controller can be configured by the Setting and
Monitoring Tool connected to the RS-232 interface or USB interface (only
WS0-CPU3 module) of a CPU module, or the port of an Ethernet interface
module.
Note The Setting and Monitoring Tool is required to configure and
commission the MELSEC-WS safety controller.
The system configuration of the complete MELSEC-WS safety
controller is stored in the memory plug. The system does not
have to be reconfigured when a module is replaced.
For the diagnostics after module replacement with the higher
version (for instance, upgraded from V1.11.0 to V2.01.0), the
Setting and Monitoring Tool version 1.7.0 is required.
