1.5 Wiring Process Peripherals
Cabinet-internal wiring is preferably carried out with plastic-insulated cables according to
DIN VDE 298 T4 2/89.
Types: H05V-K/H05V2-K (0.5…1 mm²) or H07V-K/H07V2-K (1.5…2.5 mm²).
Use only copper wires.
Due to the power dissipation in the device there is a higher temperature on the terminals than
the device ambient temperature. This increase is maximum 15°K with full load. For this reason
the isolation of the wires must withstand a higher temperature than the device environment
temperature.
Example:
Max. ambient temperature Max. operating temperature Cross section
55°C 70°C H05V-K, H07V-K
70°C 85°C H05V2-K, H07V2-K
1.5.1 Peripheral Connectors
The construction of the peripheral connectors is designed for direct peripheral wiring. That
means, that the wiring can be carried out without the use of a routing terminal or other addi-
tional screw terminals.
Removable screw terminals are used as peripheral connectors. These are attached to the de-
vice for delivery.
Optionally spring-loaded- or crimp terminals can be used.
Cable cross sections up to 2.5 mm² can be used. If a wire bridge with 0.75 mm² is used or a
bridged comb, the cable cross section is limited to 1.5 mm².
Preferably wire end sleeves are to be used.
A cable duct is to be provided for the wiring of the process signals.
