Do not shrink the cord-entry seal until it has been ascertained that unit is functioning. • ONLY CONNECT THIS TO 24 V AC or 12 V DC CLASS 2 POWER SUPPLY. • To prevent fire or electric shock hazard, the UL listed wire VW-1 style 1007 should be used for the cord for Input Terminals. • Do not use a transformer larger than 10 VA. Cord length and wire gauge 24 V AC The recommended cord length and copper wire size are shown in the table for reference. The voltage supplied to the camera should be between 19.5 V AC and 28 V AC.
