3.9.5 Power supply insolation
The C6 P34 PANEL power supply is galvanically isolated which means its output is elec-
trically separated from its input. This feature has many benefits:
• Increases the noise immunity of the system
• Avoids input short circuits in systems with the power supply grounded
• Breaks ground loops which may cause interferences in the video signals.
3.9.6 Power supply connection
• The device has to be connected to a 24 VDC (18-32VDC) power supply which
satisfies the requirements of safe extra low voltage (SELV) in accordance with
IEC/EN/DIN EN/UL60950-1.
• Remove the two poles plug connector from the system.
• Connect the positive and the negative poles (also refer to the label on the back
of the system) to their respective terminals of the two pole plug connector. Use
wires with a cross-section of 1.5 mm
2
(AWG16). Always check that the voltage
drop along the supply wiring is not excessive and the input voltage remains
above the minimum required (18VDC) in the worst load condition.
• Connect the ground cables (PE) to the earthing points.
