CONTROL PANELS CP600 2ND GENERATION
CP600 2nd generation, 2, en_US 17
8 Power supply, grounding and shielding
The power supply terminal block is shown in the figure below.
3 conductors 1,5 mm
2
wire size minimum, minimum temperature conductor rating 105 °C.
Ensure that the power supply has enough power capacity for the operation
of the equipment.
The unit must always be grounded to earth with 1,5 mm
2
wire size minimum. Grounding helps
limit the effects of noise due to electromagnetic 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 con-
nect 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 1 MΩ resistor in parallel with a 4,7 nF capacitor. The power supply must have
double or reinforced insulation. The suggested wiring for the power supply is shown below.
