• Be careful not to use cables that seem worn or old.
• 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.
• Use only original spare parts. Non-original spare
parts could cause fire, electrical discharge or other
hazards.
• Before proceeding with installation, check the
supplied material to make sure it corresponds
to the order specification by examining the
identification labels (4.3 Product marking, page
11).
• 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.
• The product is designed to house only cameras
that are properly certified.
• The maximum nominal value of the camera must
be 12Vdc, 18W max (57Vdc, 13W max for PoE
versions).
• A power disconnect device must be included
in the electrical installation, and it must be very
quickly recognizable and operated if needed.
• The separate protective earthing terminal provided
on this product shall be permanently connected
to earth.
• To connect the power supply line use the
appropriate junction-box (UPTJBUL). For further
information, refer to the product use and
installation manual.
MNVCU2_2222_EN
• 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.
• The device must be properly connected to the
earth circuit.
• Equipment intended for installation in Restricted
Access Location performed by specialist technical
staff.
• Connect the device to a power source
corresponding to the indications given on the
marking label. Before proceeding with installation
make sure that the power line is properly isolated.
The supply voltage should never exceed the limit
(±10%).
