• Comply with all the national standards during the
device installation.
• This device was designed to be permanently
secured and connected on a building or
on a suitable structure. The device must be
permanently secured and connected before any
operation.
• Before proceeding with installation, check the
supplied material to make sure it corresponds
to the order specification by examining the
identification labels (4.2 Product marking label,
page 7).
• Any device which could be installed inside the
product must comply with the current safety
rules.
• If the installation is NEMA TYPE 4X, the installer
must replace the cable glands of the product with
NEMA TYPE 4X cable glands.
• For all connections, use cables that are able to
withstand temperatures of at least 75°C (167°F).
• The product is designed to house only cameras
that are properly certified according to IEC/UL
60950-1 or IEC/UL 62368-1 (7W max).
• A power disconnect device must be included
in the electrical installation, and it must be very
quickly recognizable and operated if needed.
• To connect the power supply line use the
appropriate junction-box (UPTJBUL). For further
information, refer to the product use and
installation manual.

• Use Listed tube crimping lugs for the connection
of the network conductors to the terminals. The
copper tube crimping lugs must be suitable for
the type of installation (from -20°C (-4°F) a +80°C
(+176°F) min., V-0). Copper tube crimping lugs
examples: RP, BP o YP (Cembre).
• Installation category (also called Overvoltage
Category) specifies the level of mains voltage
surges that the equipment will be subjected
to. The category depends upon the location
of the equipment, and on any surge voltage
protection provided. Equipment in an industrial
environment, directly connected to major
feeders/short branch circuits, is subjected to
Installation Category III. If this is the case, a
reduction to Installation Category II is required.
This can be achieved by use of an insulating
transformer with an earthed screen between
primary and secondary windings, or by fitting
UL listed Surge Protective Devices (SPDs) from
live to neutral and from neutral to earth. Listed
SPDs shall be designed for repeated limiting of
transient voltage surges and the following rated
operation conditions: Type 2 (SPDs permanently
connected to the power network and intended
for installation on the load side of the service
equipment); Nominal Discharge Current (In)
20kA min. For example: FERRAZ SHAWMUT,
STT2240SPG-CN, STT2BL240SPG-CN rated
120Vac/240Vac, (In=20kA). Maximum distance
between installation and reduction is 5m.
