programming software.
Make the connection with
the device powered and
with inputs and outputs
disconnected.
• Installation notes
Always power the devices by means of the TRAFO1 transformers specified in the manual (one for each device) when:
• The application is unknown.
• Multiple devices have input signals that are not isolated from one another, such as, for example: non-isolated grounded thermocouples, transducers or transmitters
powered by a single supply, linear inputs with voltage or current not isolated from one another.
• It is a general rule that devices with shared signals (probes, transmitters, signal retransmission, etc.) must be powered by a separate transformer for each device.
• Any special cases not covered by the above example must be evaluated from time to time.
• One possible example of a power supply by a single transformer is the case of devices with RTD or PTC probes, with relay or logic outputs connected to individually
isolated devices (such as GTS static groups).
ATTENTION: in case of an input with a NON-isolated grounded thermocouple, the secondary of the power transformer for the device CANNOT be grounded: doing so
will cause the device to fail, with probable blowing of the internal fuse.
