9.1. 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 (0.5-1mm²), H07V-K (1.5-2.5).
The use of lead sleeves is recommended.
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
additional screw terminals.
For the wiring, cable ducts are to be provided at both sides of the modules (refer to chapter
3.2.3 , " Space Requirement ").
Warning
The activities described in this chapter presume that the grounding connection between SICAM TM and
cabinet or rack has been properly carried out and that these are earthed.
Warning
For modules that operate with voltages >60V (e.g.: DO-6212, DI-6101) care must be taken that
manipulation on the peripheral connectors may only be carried out in a de-energized state.
The reason for this is that when withdrawing the upper peripheral connector under voltage, the external
voltage can be conducted through the lower peripheral connector still connected. The pins of the upper
peripheral connector now freely accessible will now conduct the external voltage.
