6.1 General wiring guidelines
Please note:
}
Information given in the "Technical details" must be followed.
} Max. continuous current that the external power supply must provide: 160 mA
}
Use copper wiring that can withstand temperatures of up to 75 °C.
}
Always connect the mounting rail to the functional earth via an earthing terminal. This
will be used to dissipate hazardous voltages in the case of a fault.
}
Separate the supply voltage cable from the analogue input current lines.
}
For transducers located outside the control cabinet: Where the cable enters the control
cabinet, the cable shield must be connected to the earth potential over a wide surface
area and with low impedance (connect in star).
}
The power supply must meet the regulations for extra low voltages with protective sep­
aration.
Please note the following when connecting the interfaces:
}
The following minimum requirements of the connection cable and connector must be
met:
–
–
–
} Measures to protect against interference:
–

6.2.1 Cable requirements
Screw terminals:
} Minimum conductor cross section on field connection terminals = 0.25 mm
}
Maximum conductor cross section on field connection terminals for the functional earth
= 2.5 mm
}
Torque setting with screw terminals: 0.50 Nm.

INFORMATION
Only connect and disconnect the Gateway when the supply voltage is
switched off.
Only use standard industrial Ethernet cable and connectors.
Only use double­shielded twisted pair cable and shielded RJ45 connectors (indus­
trial connectors).
Only use 100BaseTX cable in accordance with the Ethernet standard (min. Cat­
egory 5)
Ensure the requirements for the industrial use of CANopen are met, as stated in the
Installation Manual published by the User Group.
