4.7 Cable and connector assignment
The casing of the standard data cable for the SLG used with MOBY is polyurethane (PUR
according to VDE 0250). This provides excellent protection to the cable against oils, acids,
alkalies and hydraulic fluids.
4.7.1 Cable configuration
The cable between the PC and SLG must have three cores and a shield.
The data can be transferred largely independently of the wire diameter over distances of up
to 30 m (depending on the baudrate).
Standard cable recommended by Siemens: LiYC11Y
Grounding of the SLG cable
It is generally recommended that the shield is connected to a ground rail over a large surface
area.
Trailing cable
The SLG can also be connected over a cable suitable for trailing.
Recommended cable type: HPM Paartronic 3340-C-PUR 3 2 0.25.
Power supply for SLG D1x
Power is supplied to the SLG D1x over a 4-pin M12 connector.
It is essential to consider the voltage drop over the supply cable.
The permissible length of the power supply cable depends on the power consumption of the
SLG and the resistance of the connecting cable.
