1.3.1
Mounting
Precondition for the mounting of the SICAM I/O Modules is, that the SICAM A8000 System
which should be expanded, is already mounted on the DIN rail. Then you can mount the bus
connector which is delivered with the SICAM I/O Module on the DIN rail and press it into the
connector of the Master Module (in case of CP-8000 in the connector of the coupling module).
Afterwards you can plug the SICAM I/O Module on the bus connector.
Warning
The removal and attachment of energized modules is not allowed.
For modules that operate with voltages >60 V, care must be taken that manipulation on the peripheral
connectors may only be carried out in a de-energized state.
The display (LCD, LED) of the modules do not grant a guarantee that the peripheral connectors are de-
energized.
Note
For details about the mounting refer to the manual
SICAM A8000 Series CP-8000, CP-8021, CP-8022.
Caution
Bus communication is system-internal only. It is not allowed to modify the bus connector.
The devices must be powered by a SICAM A8000 power supply only. For USA and Canada: Use a UL
listed SICAM A8000 power supply.
1.3.2
Electrical Connection
Check the adherence of the specified limit values.
Connect the process-devices to the screw terminals. 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°C with full load. For this
reason, the isolation of the wires must withstand a higher temperature than the device
environment temperature.
