• When installing the device, comply with all the
national standards.
• This device was designed to be permanently
installed on a building or on a suitable structure.
The device must be installed permanently 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 markings, page 7).
• Any device which could be installed inside the
product must comply with the current safety
standards.
• 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 (7W max).
• A disconnecting device, readily and easily
accessible, must be incorporated in the electrical
system of the building for rapid intervention.
• 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 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) 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 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
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, STT2240SPG-
CN, STT2BL240SPG-CN rated 120Vac/240Vac,
(In=20kA). Maximum distance between installation
and reduction is 5m.
