PT-Series HD Camera Installation
1.6.2
Connecting power
The camera itself does not have an on/off switch. Generally a circuit breaker will be used to apply or
remove power to the camera. If power is supplied to it, the camera will be in one of two modes:
Booting Up or Powered On.
The power cables supplied by the installer must use wires that are sufficient size gauge (16 AWG
recommended) for the supply voltage and length of the cable run. Always follow local building codes!
To satisfy FCC requirements, the supplied noise suppression ferrite must be installed on the camera
system power cable unless power cables are enclosed in metal conduit. Refer to Figure 1-4.
Note that the heater power cable requires two-wire power. Do not connect to the power supply
ground.
Ensure the camera is properly grounded. Typical to good grounding practices, the camera chassis
ground should be provided using the lowest resistance path possible. FLIR requires using a
grounding strap anchored to the grounding lug on the back plate of the camera housing and
connected to the nearest earth-grounding point.
Note
The terminal blocks for power connections will accept a maximum 16 AWG wire size.
3/4” NPT for Cable
Gland or Conduit
