• To comply with the main supply voltage dips and
short interruption requirements, use a suitable
Uninterruptable Power Supply (UPS) to power the
unit.
• Power the device using a mains power supply
24Vac, 24Vdc or, for models without a board for
video analysis, a PSE (Power Sourcing Equipment)
in compliance with IEEE 802.3at (PoE+).
• In the case of a 24Vac power supply, you must
provide for adequate separation from the AC
power supply line using double or reinforced
insulation between the main power supply line
and the secondary circuit.
