3 Safety rules

DANGER!

Explosion hazard.

Read carefully to avoid danger of explosion.

• Installation and maintenance of the appliance

must be carried out by specialist technical sta in

compliance with the applicable reference code

EN/IEC 60079-14, EN/IEC 60079-17 and national

standards.

• Installation should be carried out using adequate

tools. The location in which the device is installed

may require use of specic tools.

• CAUTION! The external equipotential connections

must be set up through the eyelet on the outside

of the product. Do not use as a protective terminal.

Use cables with a minimum section equal to: 4mm²

(11AWG).

• The equipotential connection is mandatory to

avoid the risk of ignition of products installed in

potentially explosive environments.

• Do not open the device when powered and in

explosive atmosphere.

• Make all connections, installation and maintenance

work in a non-explosive atmosphere.

• 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 ambient

temperature, without taking into consideration

direct sunlight.

• Make sure that the unit and other components of

the installation are closed so that it is impossible to

come into contact with live parts.

• Ensure that the sealing of cable entry systems (if

any) has been performed properly and the time of

glue hardening has been observed.

The equipotential connection must be carried out

using an external cable with a minimum 4mm²

section (11AWG).

Connect the cable for the earthing equipotential

connection with the eyelet terminal supplied

(suitable for cables with 4mm² up to 6mm² section).

Fix the eyelet using the screw (M5) and washer.

Characteristics of the M5 screw:

• Material: A4 Class 70

• Screw head: ISO 4762

• Length: 8mm (0.3in)

compressed air must not be used.

8 Information on disposal

and recycling

The European Directive 2012/19/EU on Waste

Electrical and Electronic Equipment (WEEE) mandates

that these devices should not be disposed of in the

normal ow of municipal solid waste, but they should

be collected separately in order to optimize the

recovery stream and recycling of the materials that

they contain and to reduce the impact on human

health and the environment due to the presence of

potentially hazardous substances.

The symbol of the crossed out bin is marked

on all products to remember this.

The waste may be delivered to appropriate collection

centers, or may be delivered free of charge to the

distributor where you purchased the equipment at

the time of purchase of a new equivalent or without

obligation to a new purchase for equipment with size

smaller than 25cm (9.8in).

For more information on proper disposal of these

devices, you can contact the responsible public

service.
