Safety
This section includes general safety instructions for handling Weidos devices. Specific warning notices for
specific tasks and situations are given at the appropriate places in the documentation. Failure to observe the
safety and warning notices may result in damage to persons and material.
2.1
General Safety Notice
Consider the following steps to follow. A false manoeuvre could be the cause of an accident or material
damage.
Do not disassemble or modify the modules. This could lead to breakdowns or malfunctions and could lead to
injuries or fire.
- All types of radio communication devices, including mobile phones and personal handy-phone systems
(PHS), must be kept more than
25cm
away from the controller in all directions. Failure to observe this
precaution exposes malfunctions caused by excess of temperature.
- Disconnect the external power supply of the system (on all phases) before connecting or disconnecting a
module. Failure to observe this precaution may cause faults or malfunctions of the module.
- Before handling a module, dispose of the electrostatic charge accumulated by the human body by touching
a suitable conductive object. Failure to observe this precaution may cause faults or malfunctions of the
module.
Fuse protection
The operator must set up the equipment so that it is protected against overloading. The 12V DC or 24 V DC
power supply units used must fulfill the SELV category, no matter whether they supply the system or feed-in
modules. The output voltage of the feed-in power supply has to fulfill overvoltage category 1 according to
IEC 61010.
Electromagnetic Compatibility RED Directive
The IEC 61000 standard on immunity requirements for electromagnetic compatibility applies to standard and
additional wireless communications in Weidos products.
The immunity requirements have been selected to ensure an adequate level of immunity for devices used in
industrial settings. The equipment meets the essential electromagnetic compatibility requirements
concerning immunity.
According to the regulations that are part of EN 61131-2: 2007 and specifically, the sections
61000-6-2 for immunity and 61000-6-3 for emissions, Weidos models ensure the smooth operation of all
your wireless networks in industrial and / or domestic environments.
