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 safe separation.
Information
Only connect and disconnect the Gateway when the supply voltage is
switched off.
Please note the following when connecting the interfaces:
} The following minimum requirements of the connection cable and connector must be
met:
– Only use standard industrial Ethernet cable and connectors.
– Only use double-shielded twisted pair cable and shielded RJ45 connectors (indus-
trial connectors).
– Only use 100BaseTX cable in accordance with the Ethernet standard (min. Catego-
ry 5)
} Measures to protect against interference:
– Ensure the requirements for the industrial use of EtherCAT are met, as stated in
the Installation Manual published by the User Group.
Wiring the units
Cable requirements
Screw terminals:
} Minimum conductor cross section on field connection terminals = 0.25 mm 2 (AWG24),
} Maximum conductor cross section on field connection terminals for the functional earth
= 2.5 mm 2 (AWG12),
} Torque setting with screw terminals: 0.50 Nm.
