l The manufacturer declines all responsibility for any damage caused by an improper use of the appliances
mentioned in this manual. Furthermore, the manufacturer reserves the right to modify its contents without
any prior notice. The documentation contained in this manual has been collected with great care. The
manufacturer, however, cannot take any liability for its use. The same thing can be said for any person or

l Before starting any operation, make sure the power supply is disconnected.
l Be careful not to use cables that seem worn or old.
l Never, under any circumstances, make any changes or connections that are not shown in this handbook.
Improper use of the appliance can cause serious hazards, risking the safety of personnel and of the
installation.
l Use only original spare parts. Non-original spare parts could cause fire, electrical discharge or other
hazards.
l Before proceeding with installation, check the supplied material to make sure it corresponds to the order
specification by examining the identification labels (Product marking).
l 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.
l 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 external surge 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, 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, suitable rated for operating voltage and designated as follows: Type 2
(Permanently connected SPDs intended for installation on the load side of the service equipment
overcurrent device); Nominal Discharge Current (In) 20kA min. For example: FERRAZ SHAWMUT,
STT2240SPGCN, STT2BL240SPG-CN rated 120Vac/240Vac, (In=20kA). Maximum distance between
installation and reduction is 5m.
l Any device which could be installed inside the product must comply with the current safety standards.
l If the installation is NEMA TYPE 4X, the installer must replace the cable glands of the product with NEMA
TYPE 4X cable glands.
l For all connections, use cables that are able to withstand temperatures of at least 75°C (167°F).
l The product is designed to house only cameras that are properly certified (7W max).
l A power disconnect device must be included in the electrical system, and it must be very quickly
recognizable and operated if needed.
l To connect the power supply line, use an appropriate junction box. For further information, refer to the
product use and installation manual.
l Use Listed copper 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] to +80°C [+176°F]
min., V-0). Copper tube crimping lugs examples: RP, BP o YP (Cembre).
