Introduction
1.6 Product-specific information
ESD guidelines
ESD components are destroyed by voltage and energy far below the limits of human perception.
Voltages of this kind occur as soon as a device or an assembly is touched by a person who is not
electrostatically discharged. ESD components which have been subject to such voltage are
usually not recognized immediately as being defective, because the malfunction does not occur
until after a longer period of operation.
NOTICE
Damage to the speed monitor from electrostatic charging!
The speed monitor contains electrostatically sensitive devices. These modules will be
destroyed or damaged by improper handling.
• You must discharge your body electrostatically immediately before touching an electronic
• Always hold the component by the plastic enclosure.
• Electronic modules should not be brought into contact with electrically insulating materials
• Always place electrostatic sensitive devices on conductive bases.
• Always store and transport electronic modules or components in ESD-safe conductive
Note
In the case of capacitive or inductive load at the output contacts, sufficient suppressor circuits
must be provided to protect against contact overload. A fuse must also be connected in series
to protect against welding of the safety contacts (see Chapter "Technical data (Page 71)").
Note
Routing of the sensor cables
If electromagnetic interferences are to be expected, all initiator/encoder cables must be shielded
when laid. The shielding must be connected to PE at both ends.

switch cabinet or the water pipe.
