Relevant Standards
These terminals have been manufactured in accordance with:
• Standard EN IEC 60079-0 (2018) and IEC 60079-0 (2017): Explosive
atmospheres - Part 0: Equipment - General requirements.
• Standard EN IEC 60079-7 (2015) + A1 (2018) and IEC 60079-7 (2015) +
A1 (2017): Explosive atmospheres - Part 7: Equipment protection by
increased safety “e”.
• Standard EN 60079-15 (2010) and IEC 60079-15 (2010): Explosive
atmospheres - Part 15: Equipment protection by type of protection “n”.
• Standard EN 60079-31 (2014) and IEC 60079-31 (2013): Explosive
atmospheres - Part 31: Equipment dust ignition protection by enclosure “t”.
DANGER
POTENTIAL FOR EXPLOSION
Install, use, and maintain these modules in accordance with:
• Standard IEC 60079-14: Explosive atmospheres - Part 14: Electrical
installations design, selection and erection.
• Standard IEC 60079-17: Inspection and maintenance of electrical
installations in hazardous areas.
• Edicts, by-laws, laws, directives, circulars, standards, regulations and any
other document relating to where the apparatus is installed.
Failure to follow these instructions will result in death or serious injury.
Permitted zones of application
Refer to the section "Markings" to get information about the permitted zones of
protection and the types of protection.
• The product installed in zones 2/22 hazardous areas must be certified and
bear the marking.
• Ensure with the marking that the terminals are compatible with the
conditions permitted for the hazardous area at the site where it is being
used.

Installation, Operation and Maintenance
Make sure you follow all the recommendations in the user manual for each
product and additionally those listed below.
DANGER
POTENTIAL FOR EXPLOSION
• Confirm that the location is free from explosively hazardous gases or dust
before connecting or disconnecting equipment, replacing or wiring modules.
• Make sure that the ambient temperature in protective enclose never exceeds
the temperature marked on the product.
• Confirm each interface (COM, Ethernet, USB, power line, …) has been
securely locked.
• Confirm that any USB cable has been attached with its appropriate clamp.
• Install the modules in an enclosure EPL Gc insuring a minimal ingress
protection IP54 for use in zone 2 and in an enclosure EPL Dc insuring a
minimal ingress protection IP6X for use in zone 22.
• Make sure the purging test inside the product is performed and validated in
accordance with IEC 60079-2 when installed in an IP4X pressurized
enclosure.
• Do not install the modules in the environment more than Pollution Degree 2
as defined in IEC 60664-1.
• Do not open the enclosure when an explosive atmosphere is present.
• Confirm that the power supply has been turned OFF before disconnecting,
replacing or wiring modules.
• Ensure that ground at power supply is properly connected.
• Do not use equipment that has been damaged.
• Do not expose the terminal to direct sunlight.
• Do not allow layers of dust to form on the product: it should be cleaned
regularly.
• Implement method to avoid risk of electrostatic discharge at using zone 2
and 22 areas. See the details at NOTE.
• Add the warning for potential electrostatic charging hazard in a location
visible by the operator after installation in order to maintain the required level
of safety.
• Take into consideration during the installation, that the product underwent
only a shock corresponding to an energy of a low risk at 2J.
• Mount the display in an enclosure according to the installation procedures
described in the user manual.
• Use only the identical replacement battery (HMIZGBAT) for the product.
Failure to follow these instructions will result in death or serious injury.
NOTE: The front surface of the product has risk of electrostatic discharge. If the product is
operating in zone 2/22 areas, the following instructions must be applied:
All models except for HMIDT752 and HMIDT952:
• Use non-conductive gloves (e.g. Electrosoft Latex Gloves by Honeywell Safety) made of
leather, plastic or rubber whose surface resistance is more than 1 GΩ at 23 ± 2 °C and
50 ± 5 % relative humidity.
4/8
• Use a non-conductive touch pen (XBTZGPEN by Schneider Electric) made of plastic
material whose surface resistance is more than 1 GΩ at 23 ± 2 °C and 50 ± 5 % relative
humidity to all terminals.
HMIDT752 and HMIDT952:
• Install the product away from 1,000 mm distance from a potential electrostatic source
(e.g. plant process, conveyor belt, pipe, etc). The environmental conditions shall not be
lower than 25 % relative humidity. If the potential electrostatic source is upper than 30
kV, it is necessary to call an expert to evaluate the electrostatic risk and the distance
between the product and the electrostatic source.
