Installation; Ground Connection - FLIR SR-100 PT Installation And Operation Manual

Installation

The SR-PT Thermal Imaging camera is packaged in a separate box from the pan/tilt base. The
wires from the base will need to be connected to the camera through an opening in the back of
the camera and the camera will need to be installed on the top of the pan/tilt base. Then the
connections to the assembled unit are made.

Ground Connection

The SR-PT 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 assembly. 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. If is it
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 wire on the
pan/tilt base, and from the pan/tilt base to the Earth Ground Lug inside the rear cover of the
camera. Typically the Earth ground connection will be part of the power cable bundle.
