In order to access the electrical connections for the VSR-6, SR-19, SR -35 and SR-50 cameras,
the camera must be removed from its enclosure. With the SR-100 camera, it is only necessary
to remove the rear of the enclosure (refer to section 4.0
required for the SR-100P pressurized camera.
The SR-Series provides electrical contacts in the form of screw-terminal jacks, allowing it to
receive 10-28 AWG tinned leads from the power supply and serial communication interface.
3.2 Ground Connection
The SR-Series cameras have grounding and surge protection to provide further immunity from
high current transients that can occur in installations that are subject to electrical storms and/or
nearby lightning events. In order to ensure CE and FCC compliance as well as to protect
against these high current events, installers are required to provide an Earth connection to a
specific connection on the camera. Note: a ground connection to the exterior of the camera (for
example, to the mounting foot) is insufficient.
When the camera is shipped from FLIR, an internal ground wire (green) connects the interface
board to the Earth Ground Lug, located on the inside of the rear of the enclosure
disconnected during the installation, it must be reconnected. For proper installation, a ground
connection from an external Earth ground must be connected to the Earth Ground Lug as
shown in Figure 8: Earth Ground Connection. Typically the Earth ground connection will be part
of the power cable bundle.

Caution! The camera must be installed according to industry-standard practices and local
electrical codes. Failure to properly connect the enclosure and the electrical interface board to
ground could result in damage to the camera and possible bodily injury.

On the SR-100P camera, the Earth Ground Lug is located on the outside of the rear of the enclosure.
