3.1.2 Description
Chapter 3 details how to install a VG4 AutoDome to a Roof Parapet or to a Pipe mount. Any

3.2 Pre-installation Check List
1. Determine the location and distance for the power supply box based on its voltage and
current consumption. See Section 5 Cable and Wire Standards, page 88 for wiring
information and distances.

fiber optic cabling. See Section 5 Cable and Wire Standards, page 88 for video and control
protocol methods.

which it will be used.
5. If this AutoDome installation utilizes the AutoTracker feature, refer to
Section A Installation Notes for AutoTracker, page 102 , before mounting the AutoDome.
NOTICE! Power and I/O cabling must be routed separately inside different permanently
earthed metal conduits.
