Risk of explosion due to electrostatic
discharge.
• The product is intended for fixed installation and
the user shall not frequently touch the product in
service (other than maintenance).
• Take suitable measures to ensure that no
electrostatic discharges can build up in the
classified area.
• The device should be cleaned using a damp cloth;
compressed air must not be used.
• Make sure that all personnel and equipment are
correctly grounded.
• Install only when the environmental relative
humidity is over the 30% (stable, ever or for long
time) or in ambient with humidity control system.
• Do not install in a location where the electrostatic
charge can increase without technical solutions
able to avoid electrostatic charge allowed in IEC/TS
60079-32-1, TR 600079-32-1 and/or in IEC 60079-14
standards. Example:
• Locations near ventilation systems.
• Locations where there is a risk of an increase in
electrostatic charge caused by compressed air
and dust.
• Locations in hightly charge generating
processes such as highly charge generating
processes, mechanical friction and separation
processes of dust, pneumatic powder conveying
flow, liquid droplet spraying or charge spraying
application.

DANGER!
High level hazard.
Risk of electric shock. Disconnect the
power supply before proceeding with any
operation, unless indicated otherwise.
• Make sure that the power is off when installing or
carrying out maintenance, with the circuit-breaker
open.
• A power disconnect device must be included
in the electrical installation, and it must be very
quickly recognizable and operated if needed.
• The electrical system to which the unit is
connected must be equipped with a 10A max
automatic bipolar circuit breaker. The minimum
distance between the circuit breaker contacts
must be 3mm (0.1in). The circuit breaker must
be provided with protection against the fault
current towards the ground (differential) and the
overcurrent (magnetothermal).
• The device can only be considered to be switched
off when the power supply has been disconnected
and the connection cables to other devices have
been removed.
• Be careful not to use cables that seem worn or old.
• All the cables must comply with IEC60332-1-2, IEC
60332-1-3 and IEC/EN60079-14.
• When commencing installation make sure that
the specifications for the power supply for the
installation correspond with those required by the
device.
• For continued protection against risk of fire,
replace only with same type and rating of fuse.
Fuses must be replaced only by service personnel.
• This equipment is not suitable for use in locations
where children are likely to be present.
