Important Safeguards
1.1.
Warnings
•
Read this manual fully before attempting installation.
•
Do not install this product near flammable or explosive
materials.
•
Installation must be performed by qualified service
personnel in accordance with the national and local safety
codes.
•
Ensure any lift equipment used employs proper safety
features.
•
Cut off power to the unit before servicing.
•
Do not exceed 30VAC on 24 volt models. Operation
above 30VAC violates low voltage operation (Class 2)
specifications. Normal operation is 24VAC.
•
Be careful not to drop the camera module or camera
housing during installation.
•
Do not install this dome in any environment exceeding
the environmental conditions described below.

Lightning-Proof Requirements
Refer to Figure 1 throughout this section.
•
Maintain a minimum of 50 meter (164 feet) distance from
any high voltage cables or equipment.
•
Run outdoor rated cable under building eaves if possible.
•
Run cabling to the site in buried, sealed steel tubes
(conduit). In areas exposed to the elements, shield the
cables with steel conduit. Connect the conduit to ground
at a single point; connect the ground to a Bus.
•
In strong thunderstorm or high faradic zones (such as high
voltage transformer substations), extra strong lightning
proof equipment and a lightning rod must be employed.
•
Take the building lightning proof requirements into
account to design the lightning proof and grounding
system of outdoor equipment and cable. Ensure that the
system is in accordance with national and industrial
standards.
•
The system must be grounded with equal potentials. The
earth ground connection must satisfy the anti-
interference and electrical safety requirements and must
not short circuit eith the high voltage electricity net.
When the system is grounded separately, the resistance
of the ground conductor should be <4Ω
and the cross-
sectional area of the ground conductor should be
<25mm
