• To reduce the risk of ignition of hazardous
atmospheres, disconnect the equipment from the
supply circuit before opening. Keep the product
tightly closed when in operation.
• The equipment is certified for use in ambient
temperatures of -40°C to 60°C (-40°F / 140°F).
• Installation of this equipment shall be carried out
by suitably trained personnel in accordance with
the applicable code of practice IEC/EN 60079-14.
• The temperature of the surfaces of the device
is increased by exposure to direct sunlight. The
surface temperature class of the device was
determined only with ambient air temperature,
without taking into consideration direct sunlight.
• 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.
• 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.
• Make sure that the device is firmly anchored.
• A power disconnect device must be included
in the electrical installation, and it must be very
quickly recognizable and operated if needed.
• It is only allowed to open back flange of the
housing for cabling of the system. The other
flanges must be open only from the manufacturer.
• Do not use power supply cables that seem worn
or old.
• For technical services, consult only and exclusively
authorized technicians.
• 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
12).
• This device was designed to be permanently
installed on a building or on a suitable structure.
• Do not allow children or unauthorised people to
use the appliance.
• A disconnecting device, readily and easily
accessible, must be incorporated in the electrical
system of the building for rapid intervention.
• For continued protection against risk of fire,
replace only with same type and rating of fuse.
Fuses must be replaced only by service personnel.
• 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.
For devices powered at 24Vac the supply voltage
should never exceed the (+/- 10%) limit. For
devices powered at 12Vdc the supply voltage
should never exceed the (+/- 5%) limit.
