} External measures must be used to connect the terminal to the function earth (e.g.
mounting rail).
} Always connect the mounting rail to the protective earth via an earthing terminal. This
will be used to dissipate hazardous voltages in the case of a fault.
} The power supply must meet the regulations for extra low voltages with protective sep-
aration.
Connecting the supply voltage
Connect the supply voltage to the fieldbus module:
} 24 V terminal: + 24 VDC
} 0 V terminal: 0 V
} Protect the supply voltage as follows:
– Circuit breaker, characteristic C - 6 A
or
– Blow-out fuse, slow, 6A
PROFIBUS DP interface
It is possible to define which outputs on the control system will communicate with
PROFIBUS-DP. The connection to PROFIBUS-DP is made via a female 9-pin D-Sub con-
nector in accordance with the guidelines of the PROFIBUS User Group (PNO).
