The power supply terminal block is shown in the figure below.
The unit must always be grounded to earth. Grounding helps limit the effects of noise due to electroma-
gnetic interference on the control system.
Earth connection will have to be done using either the screw or the faston terminal located near the power
supply terminal block. A label helps identify the ground connection. Also connect to ground the terminal
3 on the power supply terminal block.
The power supply circuit may be floating or grounded. In the latter case, connect to ground the power
source common as shown in figure (see below) with a dashed line.
When using the floating power scheme, note that the panes internally connects the power common to
ground with a 1MΩ resistor in parallel with a 4,7nF capacitor.
The power supply must have double or reinforced insulation.
The suggested wiring for the power supply is shown below.
Fig. 6.2
All the electronic devices in the control system must be properly grounded. Grounding must be performed
according to applicable regulations.

Note:
Ensure that the power supply has enough power capacity for the operation of the equipment.
