Correct use

The MELSEC-WS safety controller fulfills 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.

The MELSEC-WS safety controller may only be used within specific operating limits

(voltage, temperature, etc., refer to the technical data in Chapter 12) in the sense of

Section 2.2 and Section 7.1. It may only be used by specialist personnel and only at

the machine at which it was mounted and initially commissioned by qualified

personnel in accordance with the MELSEC-WS manuals.

All warranty claims against Mitsubishi Electric Corporation are forfeited in the case

of any other use, or alterations being made to the software or to devices, even as

part of their mounting or installation.

 Pay attention to the safety notes and protective measures of the user's manuals

(hardware) and Safety Controller Setting and Monitoring Tool Operating Manual!

 Make sure that on the implementation of safety-related functional logic, the

regulations in the national and international standards are met, in particular the

control strategies and the measures for risk reduction that are stipulated for your

application.

 The external voltage supply of the device must be capable of buffering brief mains

voltage failures of 20 ms as specified in IEC 60204.

 The MELSEC-WS safety controller may not start up normally when power is

restored immediately after the external power supply has been shut off (within 5

seconds). To restore the power, wait for 5 or more seconds after power-off.

 The modules of the MELSEC-WS safety controller conform to Class A, Group 1,

in accordance with EN 55011. Group 1 encompasses all ISM devices in which
