Note
If older SK TU2-PBR modules are used, only normal, straight M12 plug connectors and
sockets can be used. However, angled connectors can be used with the new hardware
version (from May 2007).

2.3.3 Profibus module SK TU2-PBR-24V
The power supply for this Profibus option is via an external 24V
connection (M8 round plug connector). The Profibus participant can
therefore be identified by the master system even without a voltage
supply to the frequency inverter.
• 2x 5 pin M12 connectors
• Additional 24V supply voltage (3-pin M8 socket)
• Transfer rate of up to 12Mbit/s
• Rotary coding switch for setting the PPO type
• Rotary coding switch for address setting
The data required for this purpose are set using the three rotary coding switches. The data is read in
when the 24V (approx. 100mA) are applied.
External M8 round plug connector for 24V supply voltage connection
To connect an SK 300E / 750E with Profibus 24V option to an
existing Profibus network, special connection accessories are
required for the separate voltage supply (Section 3). An M8
socket is used, which enables compliance with the high
protection class IP55/66. The following recommended M8
components must be used for Profibus applications. 24Vdc connection assignments

Connection of the 24V supply voltage
The supply voltage is 24V DC ±25% (Pin 1 = 24V, Pin 3 = GND, approx. 100mA). A normal M8 cable
socket is used for the 24V connection.
External M12 round plug connector BUS connection
To connect an SK 300E / 750E with Profibus option to an
existing Profibus network, special connection accessories are
required (Section 3). M12 connectors are used, which enable
compliance with the high protection class IP55/66. The following
recommended M12 components are specially designed for
Profibus applications. Shielding is provided and the coding (B
coding) complies with the Profibus standard. When selecting the
connectors, care must be taken that conventional M12
components with A coding are not used. Standard assignment

Termination resistor
The termination resistor for the last bus participant can be screwed to the Bus-out socket of the of the
final frequency inverter or bus participant as the termination connector.
