E02 Electrical connection
Switch the SBU IO-Link off and secure it against being switched on again! Connect the electrical supply
cables in the control box, observing the terminal assignment in the circuit diagram.
Connect all connections according to the legal regulations and the VDE directives.
Make sure that cable cross sections and fuses are adequately dimensioned in accordance with the power
consumption.
Metallic cable glands must be connected to the earthing system. Unused holes for cable glands must be
sealed with blanking plugs.
The attachment of wire end ferrules must always be done with suitable crimping tools to ensure constant
quality of the crimping.
Measures may need to be taken against external influences if the SBU IO-Link is installed outdoors. These
could be, for example, rain roofs or an enclosure. It is the duty of the company operating the SBU IO-Link
to check this.
The potential equalisation of the SBU IO-Link takes place via the piping or via one of the three fixing
screws of the PCBs.
Only separate cable glands suitable for the application may be used for the cable entries. Connecting
threads in the switch box that are not required are sealed with suitable separately certified screw plugs.
The installation and maintenance may only be carried out by an
electrician
; refer here in particular to the
chapter "Safety".
Electrostatic charging may occur due to friction of the media 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.
Danger to life due to high voltage.
Very serious injuries or death due to electrocution.
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.
DANGER
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.
