Operating instructions - SBU IO-Link
B07
Safety information for working on the electrical system
The operating voltage required for the system may result in very serious injuries or even death if live parts
are touched. If a short circuit occurs there is a danger of sparks being generated, leading to a fire.
The system connection must be adequately dimensioned in order to prevent overloads. Switch the SBU IO-
Link off immediately in case of faults in the electricity supply.
It is forbidden to work on live active parts of the SBU IO-Link .
The SBU IO-Link must be in a safe condition and is to be kept in this condition. The SBU IO-Link must be
inspected regularly. Defects such as loose connections, etc. must be reported and rectified immediately.
The switch box is to be kept closed at all times. Only authorised personnel are allowed access to it for
inspection and maintenance.
The SBU IO-Link must be protected against indirect contact in accordance with its voltage, type of use and
place of operation so that protection against hazardous contact voltages exists in the case of a fault in the
SBU IO-Link .
DANGER
Danger to life due to high voltage.
Very serious injuries or death due to electrocution or effects on medical
implants.
Risk of falling due to electric shock.
The SBU IO-Link may only be connected by an electrician.
Switch the SBU IO-Link off and secure it against being switched on again.
Electrostatic charging may occur due to friction of the media in the pipeline and due to the possibly high
pressures. This charging can adversely affect the SBU IO-Link . The SBU IO-Link must therefore be
adequately earthed.
WARNING
Operational malfunction due to electrostatic charging.
Malfunctions of, or damage to components.
The SBU IO-Link may only be connected by an electrician.
The SBU IO-Link must be earthed.
