Prior to use
2.1 Selection of right equipment
You need to be sure that the equipment you intend to take into explosion hazardous area
matches up with the zone classification and other safety requirements related. At least the
following points should be notified prior to use:
2.1.1 Intended purpose of equipment
Please keep in mind what the actual application of equipment is. For example in case the
equipment is to be moved when connected to the supply it needs to be designed for that
purpose. If the certification is mentioning “portable” it means that the equipment is suitable
and tested for portable use. If the certification does not mention portable it means that the
equipment shall not be moved when it is in operation (reliable fixing of equipment).
Slam® -units are designed and tested for portable use.
2.1.2 Application of use (Zone XX) in accordance with equipment
category
Operator has the best knowledge of area classification at his site. To help the operators’
selection of equipment the certification is describing the equipment category. For explosion

9/16
hazardous areas there are three equipment categories. Slam® -units mentioned in this
instruction fall into Category 2 equipment.
Category 1 product is suitable for use in Zones 0, 1 and 2 / (20, 21 and 22)
Category 2 product is suitable for use in Zones 1 and 2 / 21 and 22
Category 3 product is suitable for use in Zones 2 / (22)
2.1.3 Gas explosion group (IIA, IIB or IIC) in accordance with
Equipment group (IIA, IIB or IIC)
This information is vital because the substances require different amount of energy to be
ignited. Safety requirements for equipment are not the same for different substances (e.g.
static electricity requirements).Therefore making the selection easier the gases are divided to
three different groups (IIA, IIB and IIC). Further information about the substances can be
found from EN 60079-20 (Data for flammable gases and vapours, relating to the use of
electrical apparatus).
Slam® -units mentioned in this instruction are Equipment group IIC.
2.1.4 Temperature class of the equipment
Please observe the Ignition Temperature (IT) of the substance creating the explosion hazard
at your site. Select the equipment based on IT of the substance. The temperature of the
equipment must be lower than IT. The highest temperature of the equipment is specified by
using Temperature Classes T1 to T6.
Example:
Petroleum IT is approximately 250 Celsius àMaximum allowed temperature class of the
equipment is T3 (< 200° C)
Slam® -units mentioned in this instruction are Temperature Class T4 (GASES)
Slam® -units mentioned in this instruction maximum surface temperature of 70⁰C (DUSTS)

10/16
2.1.5 Environmental criteria
Please observe the ambient temperature of the application in use because certification is
valid for temperatures between – 20°C --- + 50°C. Please see type label of the product for
further data. If the equipment is used in other temperatures than mentioned the safety can not
be guaranteed.
Selection and use of equipment is always under the responsibility of the operator.
Please note that all of the aforementioned criteria are to be passed when selecting the
equipment.
Please do not take any unnecessary risks.
