tighten to ensure water-tight fittings. PTFE tape or pipe sealant (e.g., DuPont RectorSeal
T) is suitable for this purpose.
9.7 Removing the back cover
Use a cross-head screwdriver to loosen the four captive screws and remove the cover,
exposing the connections at the back of the camera. There is a grounding wire con-
nected 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.
9.8 Connecting power
Power requirements:
24 VAC (21-30 VAC; 24 VAC: 215 VA max. with heater) or 24 VDC (21-30 VDC; 24 VDC:
200 W max. with heater).
The camera itself does not have an on/off switch. Generally, the FLIR G300 pt series
camera will be connected to a circuit breaker, and the circuit breaker will be used to con-
nect 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 en-
sure adequate current-carrying capacity. Always follow local building codes.
Ensure the camera is properly grounded. Typical to good grounding practices, the cam-
era chassis ground should be provided using the lowest resistance path possible. FLIR
Systems 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.
