Observe electrical safety regulations and good practices:
Electrical safety regulations stipulated by the appropriate technical
authorities must be observed.
Do not use if the product is damaged or diminished in any way:
Carefully inspect each module before it is installed (or re-installed).
If at any time it is observed that the condition of equipment is
diminished in any way so that there is even the slightest possibility of
incorrect functioning, it should be assumed that safe operation is no
longer possible, and the equipment should be removed immediately
so that even unintentional operation is made impossible. Examples of
such conditions are:
• Visible damage to the equipment
• Loss of electrical function/s
• Exposure to temperatures higher the specified operating limit
• Visible indication of burning
• Visible physical damage due to impact or excessive mechanical
shock
Do not attempt to open the housing or repair any of the
modules:
It is forbidden for safety control products such as this to be repaired
or modified in any way: this can diminish or render inoperative its
critical safety functions. A malfunctioning or damaged module must
be immediately removed, so that even inadvertent operation of the
system becomes impossible in such circumstances. An identical
module should be installed in its place, after the new module has
been tested to confirm that it is in proper working condition.
Opening the enclosure of a module will immediately void its
warranty.
