3.9.3 Power supply isolation
The C6 P34 BOX power supply is galvanically isolated which means its output is electri-
cally 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.
3.9.4 Power supply connection
The device may 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.
