1.3 Standard unit construction
The following list familiarizes you with some common unit features important to recognize.
End parts: Flexible, plastic-made end parts ensure shock-absorbing and harmless contact to
sensitive and hard surface in case the luminary drops to the ground even from high position. Light
construction affects the total weight of the unit itself.
Transparent PC –tube: Polycarbonate tube, being durable, flexible and lightweight plastic, brings
advantage for use. Unique antistatic treatment allows the use of PC in explosion hazardous areas.
Aluminium frame: Nearly all CentaurSlam® Hornet–units are based on use of solid but flexible
aluminium frame. Components are tightened with screws on it, making the unit tough and durable
in severe conditions. Moreover, the frame derives excessive heat out from the luminary thereby
extending lifetime of the unit.
Electronic ballast: The ballasts are independent from each others (CSH236 and CSHL236).
Under failure of one ballast, the other still continues operating. Low-voltage protection (smart-
feature) brings reliability and convenience for use, especially when operating with transformers or
with long cables.
Compact fluorescent lamp (CFL): CFL are standard types but undergo special spark-prevention
process (encapsulation) in the factory. They also have a component certificate. Light colour is cool-
white and colour temperature 4000 K –not blinding the user’s eyes but bringing appropriate help
for the user to complete his job.
Cable: Standard cable of the CentaurSlam® Hornet–series is H07BQ-F. This cable has
polyurethane (PUR) outer sleeve. PUR withstands well chemicals as well mechanical wearing.

6(16)
However, the user has an option to specify cable type in accordance with work site requirements of
own.
Socket: Optional in-built sockets (receptacles) for linking the CentaurSlam® Hornet units in series
(apart from CSH118)
Other common accessories (optional):
Antistatic protective film for PC tube against chemical splashes and other substances
Adjustable hanging straps for light fixing.

Declaration of Conformity included in the delivery.
1.4.2 Individual testing reports
Each CentaurSlam®–unit has its own individual serial number and is provided with an original,
individual testing report when leaving the factory. The year of manufacture is specified on the type
label of the equipment. Following tests have been done for CentaurSlam® Hornet–units according
to standards relating to portable luminaries for explosion hazardous area. The Declaration of
Conformity is specifying the relevant standards. The testing report which is included in the delivery
specifies the results of the factory tests for that particular unit. The testing report typically specifies
the following tests:
PE –resistance test
The purpose of this test is to measure persistence of earth conductor.

7(16)
Vital test for electrical safety as well as explosion safety because of e.g static electricity control.
The test current is 10 A (current) and the overall resistance should not exceed 0,5 ohm.
High voltage test (electrical strength)
The purpose of this test is to measure leakage current trough insulation. Vital test for revealing
broken components or similar failures which can not be identified visually.
Testing voltage applied is 2130VDC. Maximum leakage current is 5mA.
Test of expected use of equipment
The luminary is subjected to shaking and vibration –to see that all the internal wires are properly
attached and components are not loose.
Operational test of luminaire and accessories
The unit is plugged-in and checked that it is working properly after all accomplished tests above.
Visual inspection

markings attached).
2. 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).

8(16)
CentaurSlam® -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 hazardous areas
there are three equipment categories.
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)
CentaurSlam® -units mentioned in this instruction fall into Category 2 equipment.
2.1.3 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 60079-20-1
(Data for flammable gases and vapours, relating to the use of electrical apparatus).
CentaurSlam® -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 ignition temperature is approximately 250 Celsius Maximum allowed temperature
class of the equipment is T3 (< 200° C)
CentaurSlam® -units mentioned in this instruction are Temperature Class T3 (GASES)
CentaurSlam® -units mentioned in this instruction maximum surface temperature of 90⁰C (DUSTS)

9(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 --- + 40°C. Some CentaurSlam® HORNET luminaries are certified
for temperatures between –40°C --- + 40°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 fulfilled
when selecting the equipment.
Please do not take any unnecessary risks.
3. Operating instructions
3.1 Personnel
The use of the equipment is to be controlled and accepted by the operator. The personnel using
the unit have to be authorized by the operator or his representative. In case of further training of
using the equipment please contact the local supplier of this equipment.
3.2 Visual Inspection of CentaurSlam® Hornet
As for all equipment to be used inside explosion hazardous area it is recommended that before
taking the unit into Ex –area, a visual re-inspection on the unit was taken and an analysis made
that the unit is un-damaged (e.g. any part or wires are loose damaged or disconnected)
In case faults or defects on the unit are noticed, it is prohibited to take such a unit into Ex –area
until corrective actions have been made.

10(16)
3.3 Special Attention on 2-pole use (24 V or 42 V)
Certain CentaurSlam® Hornet -units are designed to be used together with step-down
transformers. Using CentaurSlam® Hornet -unit with transformers of 2-pole socket outlets (without
earthing / bonding) imposes certain extra requirements for the unit itself. All the external metal and
aluminium parts of the CentaurSlam® Hornet are replaced by the manufacturer with plastic parts or
equipped with plastic covers in order to avoid electrostatic charging and a consequent risk of
explosion. This process can only be done by manufacturer because the certification of the product.
Please inform us about your requirement for 2-pole use when placing the order. Products originally
manufactured for 3-pole use can not be modified later for 2-pole use.
Note! Lack of equipotential bonding may cause danger in Ex –area, therefore please pay special
attention to all installations of yours involving metallic parts. Static charging is especially noted on
standards referring to installations in explosion hazardous areas (e.g. EN 60079-14).
3.4 Connection to the supply
It is recommended that the unit is first connected to the mains / transformer before entering the
explosion-hazardous area. Potential equalization should be arranged by the operator prior entering
explosion hazardous area.
CentaurSlam® Hornet-units with 2-pole supply (without bonding connection) can be taken to
explosion hazardous area without connecting it to the supply first.
3.4.1 Requirements for supply (electricity)
The following main requirements should be taken into account:
Supply voltage: Variation may be maximum +/- 6% from the value stated in the unit type label.
Current: Maximum current of the system is 16 A.
Frequency: Standard 50 Hz if not otherwise stated in the type label.
Fuse protection: The supply has a fuse with a breaking capacity of at least 1500 A
Earth Leakage Circuit Breaker (ELCB): It is recommended to use a supply with 30 mA ELCB.
Please observe the type label for further data.

range of accessories at http://www.centaurea.fi
3.6 Linking in Series
Certain CentaurSlam® Hornet-units may be equipped with Ex –certified socket in the factory.
Sockets are considered as one option so they are added to the unit upon customer’s special
request.
In-built sockets are recommended when the illuminated area is notably large, complex or not
enough wiring points are available. Linking the units in series save time, amount of cable and
provide an opportunity to build a chain of lights to provide enough illumination in the darkness.
When linking CentaurSlam® Hornet –lights together, please take the following steps:
1) If using transformer, ensure its condition and capability to supply correct amount of voltage
and current
2) Connect the first unit outside the Ex –area
3) Then connect the other luminaries to each other one by one
4) The in-built socket is only for chaining CentaurSlam® Hornet units.
5) Fix them with accessories you have selected
6) Take the chain into Ex –area

12(16)
Amount of lights which may be connected with each other depends on the supply voltage. Here
you may see general guide-lines for linking with 5 m 3x1.5mm2(or 3x2.5mm2) cable each:

The CentaurSlam® Hornet ballast protects itself against excessive voltage drops (numerous
linking) by switching itself off. If too many units are connected to the chain, some units of the chain
will switch off. You may start up by unplugging the last units on the line.
Voltage peaks are more harmful and may damage the ballast permanently when subjected to
excessive peaks continuously.
If fluorescent tubes are flickering when the units are chained up, it may be due to excessive linking.
This may shorten notably the lifetime of fluorescent tube. Unplug the last unit on the line to ensure
proper function of the unit.
