Preparing for Installation

Make sure the mounting surface is strong enough to hold at least three times the total
weight of camera and mounting hardware.

Warning : DO NOT connect the camera to the power supply during installation.

Warning : For units intended to be installed outdoors: All wiring connecting to the unit must
be routed separately inside a different permanently earthed metal conduits (not supplied).

Warning
: Install external interconnecting cables in accordance to NEC, ANSI/NFPA70 (for
US application) and Canadian Electrical Code, Part I, CSA C22.1 (for CAN application)
and in accordance to local country codes for all other countries. Branch circuit protection
incorporating a 20 A, 2-pole Listed Circuit Breaker or Branch Rated Fuses are required as
part of the building installation. A readily accessible 2-pole disconnect device with a
contact separation of at least 3 mm must be incorporated.

Warning : DO NOT remove the protective film from the dome until the installation is
complete to protect the dome from distortions from fingerprints, oil, grease or other
contaminants.

Note : Dahua recommends attaching a “drip loop” (flex or hard conduit) during installation
to ensure condensation does not form in the mount or the conduit.
