Use a cross-head screwdriver to loosen the four captive screws and remove the cover, ex-
posing the connections at the back of the camera. There is a grounding wire connected
between the case and the back cover.

NOTE
• Be careful that gaskets are not pinched when mounting the back cover.
• Do not wipe off the grease from the gaskets when mounting the back cover. The grease is critical to
the tightness of the housing.
7.8 Connecting power
Power requirements:
24 VAC (21–30 VAC; 24 VAC: 215 VA max. with heater) or 24 VDC (21–30 VDC; 24 VDC:
195 W max. with heater).
The camera itself does not have an on/off switch. Generally, the FLIR A3xx pt series cam-
era will be connected to a circuit breaker, and the circuit breaker will be used to connect or
interrupt the power supply 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 cable supplied by the installer must use wires that are of a sufficient gauge size
(16 AWG is recommended) for the supply voltage and length of the cable run, to ensure
adequate current-carrying capacity. Always follow local building codes.
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 Sys-
tems 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.
