• 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.
• Comply with all the national standards during the
device installation.
• 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.
• Any device which could be installed inside the
product must comply with the current safety
standards.
• 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).
MNVCHTV32_2104_EN
• A power disconnect device must be included
in the electrical installation, and it must be very
quickly recognizable and operated if needed.
