4.4 Electrical connection
DANGER
Moving systems/parts throughout the production facility during set-up at
the workplace
Death or very serious injury/material damage
► Do not enter the danger zone when the system is operational.
DANGER
Risk of fire and explosion
Death or very serious injury
►
The SCTMi must not be used in environments where there is a risk of
explosion.
CAUTION
The output signals can change when the power supply is switched on or
a plug connector is plugged in.
Serious personal injury and/or damage to property
►
The electrical connection must be carried out only by persons who are able to
assess the impact of signal changes on the overall machine, facility or system.
ATTENTION
Inappropriate voltage supply
Destruction of switch
►
►
►
Only operate the switch using power supply units with protected extra-low
voltage (PELV)
The system must incorporate safe electrical cut-off of the power supply in
compliance with EN60204
Do not connect or disconnect the plug connectors when voltage is applied
The SCTMi can be operated only via IO-Link communication. To do so, corresponding
hardware components are required (IO-Link master).
The SCTMi is designed to supply sensors and actuators with potential separation. It is electrically
connected using a 5-pin M12 connector with a pin assignment that corresponds to the IO-Link
specification for class B ports.
ATTENTION
Incorrect connection with the IO-Link class B port
Poss. damage to the IO-Link master or periphery
►
When operating the IO-Link class A switch with an IO-Link master with a class
B port, ensure compliant connection and potential separation.
The maximum length of the electrical supply line is 20 meters in accordance with the IO-Link
specification.
