3.4.1 Power supply port
The internal power supply 24Vdc is galvanically isolated and protected against polarity reversal and short circuits.
The panel has a power terminal.
The connector diagram is shown in Figure 11
Note:
check that the power supply is able to deliver the power needed for correct operation of the device.
The device must always be grounded. Grounding helps limit the effects of electromagnetic noise on the control
system. All electronic devices of the control system must be grounded. Ground the devices in a manner confor-
ming to applicable standards and regulations.

To limit susceptibility to noise of the GF_LOOPER 57CT programmer you have to install an electromagnetic emis-
sion suppression core as shown in figure 12.
This component, supplied with the product, is a ferrite core coated in plastic for round section wires.
