2.7 Residual hazards and protective measures
VIBGUARD IIoT is verifiably safe assuming it is used as intended. The following damage may occur if operated incor-
rectly or used improperly:
Personal damage
Damage to the system or to the machine
Danger due to running machine!
During installation and maintenance work on the machine, there is a risk of injury from moving machine com-
ponents.
l
Shut down the entire machine system and secure it against unintentional restarting.
Danger due to electric shock!
There is a risk of injury due to low voltage when working on the switch cabinet when it is open (230 V).
l
Observe the safety markings on live components.
l
Before carrying out any installation, repair or maintenance work, disconnect the system from the power sup-
ply, determine that there is no voltage and secure the power supply against being switched on again.
l

Danger due to improperly laid cables
Personnel may stumble over an improperly laid cable and injure themselves. The cable can be damaged due to
external influences.
l
Lay the cable in such a way that no one can stumble over it.
l
Use cable ties or a Velcro fastener to fix the cable in place.
l
Lay the cable in a cable duct or protective tube.
Damage due to electrostatic discharge
During installation, repair and maintenance work on the system, the electronic components can be damaged if tou-
ched due to electrostatic discharge.
l
Use an earthing strap if contact with the components cannot be ruled out.
Damage due to contamination
In a loaded industrial environment, the system components may have their function impaired or be damaged due
to contamination or moisture when the switch cabinet is open.
l
Keep the switch cabinet closed as much as possible.
Incorrect measurements due to electromagnetic interference
High frequency rays or electrostatic discharge in the vicinity of the system and measuring equipment can lead to
incorrect measurements.
l
Do not lay the sensor cables in the vicinity of heavy current lines.
l
Select an installation site with low electromagnetic radiation exposure.
