GAS AND COMBUSTIBLE DUST ATMOSPHERE EQUIPMENT
Explosion protection for:
- Gas Atmosphere Protection “e”, Level “ec” (increased safety)
- Combustible Dust Enclosure “t”, Level tc
Voltage Tolerance: ±10%
Duty Cycle: 100% ED
Ambient Temperature: -10°C <Ta<+50°C
ASSEMBLY CONDITIONS
•The connector must guarantee IP65 protection (complying to IEC 60529)
•The M3x31 screw must be tight with a maximum torque of 0.6 Nm.
•Assembling and commissioning must only be carried out by qualified and authorized persons.
•Install away from heat sources that can affect its thermal class.
•Make sure that the assembly is done in clean conditions.
INFORMATION FOR SAFE USE AND RESIDUAL RISKS
Before Installing and using product, read carefully the following notes:
Respect of maintenance indications:
It is requested to follow carefully the indications about maintenance reported in the paragraph
“PERIODICAL INSPECTION AND MAINTENANCE”, with particular reference about product cleaning.
If it is not respected, it could cause an overheating, and an ignition source for explosion could be created.
Use not allowed of product:
It is requested to use the product at ambient conditions indicated in general information, reported below:
- Tmin and Tmax: -10°C and +50°C
- Voltage tolerance ±10% of Nominal Voltage
A use not in compliance with the conditions reported above could cause an ignition source.
The devices are not resistant to exposure to direct sunlight or exposure to other sources of UV radiations for
extended periods. If necessary, provide the use of suitable protective shield and proper measure to prevent their
removal. Do not energize the coil if not correctly assembled with its own valve; incorrect assembly can increase
power absorption and therefore generate abnormal overheating.
Product encapsulation deterioration, due to mechanical impact:
Coil encapsulation in plastic material is a protection system from explosion.
It is therefore required to install the product in a zone protected from mechanical impacts.
Product wrong connection or disconnection:
In order to prevent the creation of electrical arcs, it is necessary to connect and disconnect the product when
power supply off and when explosive atmosphere is not present.

PERIODICAL INSPECTION AND MAINTENANCE
In order to prevent failures and risks, respect the following indications:
CONTROL DESCRIPTION
FREQUENCY
Verify visually integrity of the product surface.
If the product is damaged, deformed or has been corrupted by any
modification from original shape and aspect, substitute it.
Weekly
Clean the surface with wet clothes or antistatic products with power supply
switched off, in order to prevent electrostatic charges.

Description
Equipment in category 3 is intended for use in areas in which
explosive atmospheres caused by gases, vapors, mists, or air/dust
mixtures are unlikely to occur or, if they do occur, are likely to
do so only infrequently and for a short period only.
Equipment in this category ensures the requisite level of
protection during normal operation.
The resulting Marking is:
Where:
Specific marking of explosion protection
Category 3 - see the board above
Explosive gas atmospheres
Explosive atmosphere in the presence of combustible dust
Type of protection for explosive gas atmospheres – increased safety
Type of protection for explosive dust atmospheres – protection by enclosure
Temperatura class: T5/T6 for Gas, T 95°C / 80°C for Dust
Equipment protection level [EPL] for explosive gas atmospheres
Equipment protection level [EPL] for explosive dust atmospheres
Group II - Electrical apparatus for places with a potentially explosive atmosphere, other than
mines susceptible to firedamp
The symbol Ex indicates that the electrical apparatus corresponds to one of the protection type
reported in EN 60079 - 0
Electrical equipment of Group II is subdivided according to the nature of the explosive gas
atmospheres – IIC, a typical gas is hydrogen
Electrical equipment of Group III is subdivided according to the nature of the explosive dust
atmospheres – IIIC, conductive dust
