Videotec NVX220W01A Manuel D'instructions page 11

• 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 (5.3 Product marking, page
11).
• Since the user is responsible for choosing the
surface to which the unit is to be anchored, we
do not supply the fixing devices for attaching the
unit firmly to the particular surface. The installer is
responsible for choosing fixing devices suitable for
the specific purpose on hand. Use methods and
materials capable of supporting at least 4 times the
weight of the device.
• Choose an installation surface that is strong
enough to sustain the weight of the device, also
bearing in mind particular environmental aspects,
such as exposure to strong winds.
• 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.
• Make sure the product is to be secured to building
before operation.
• Equipment intended for installation in Restricted
Access Location performed by specialist technical
staff.
• Handle the product with care to avoid accidental
contacts, sharp edges and corners.
• The main insulation must be set up externally to
the product by a safety transformer and/or an
insulated direct current power supply unit.
MNVCNVX_2110_EN
• To feed the product use a safety transformer
and/or a voltage isolated power supply with the
appropriate characteristics. The characteristics
of output power must not exceed the following
values. Supply voltage: 24Vac (±10%) or 24Vdc
(±5%).
• A power disconnect device must be included
in the electrical installation, and it must be very
quickly recognizable and operated if needed.
• For technical services, consult only and exclusively
authorized technicians.
• Use adequate personal protective equipment
during installation.
• Comply with all the national standards during the
device installation.
• This is a Class A product. In a domestic
environment this product may cause radio
interference. In this case the user may be required
to take adequate measures.
• 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.
• To comply with the main supply voltage dips and
short interruption requirements, use a suitable
Uninterruptable Power Supply (UPS) to power the
unit.
• Power the device using a mains power supply
24Vac, 24Vdc or, for models without a board for
video analysis, a PSE (Power Sourcing Equipment)
in compliance with IEEE 802.3at (PoE+).
• In the case of a 24Vac power supply, you must
provide for adequate separation from the AC
power supply line using double or reinforced
insulation between the main power supply line
and the secondary circuit.
