Handling Precautions

When installing the EtherCAT Communication Unit and the SmartSlice I/O Units, observe the following

handling precautions

• Always turn OFF the power supply to the EtherCAT Communication Unit, the SmartSlice I/O Units
and the external I/O, before mounting or dismounting a Unit or connecting or disconnecting cables.
• Do not connect or disconnect the EtherCAT Communication Unit's communication cable while the
EtherCAT network is operational. Short-circuits or poor contacts in the EtherCAT cable may prevent
normal communication.
• Ensure that the power supplies for the EtherCAT Communication Unit and the SmartSlice I/O Units
and the external I/O are wired correctly.
• Provide separate conduits or ducts for the I/O and communication lines to prevent noise from
high-tension lines or power lines.
The SmartSlice I/O system is installed and set up as an EtherCAT Slave. The EtherCAT
Communication Unit's communication connector connects to the Master Unit through an EtherCAT
communication cable. Up to 64 SmartSlice I/O Units can be connected to one GRT1-ECT Unit.
