4. CONSTRUCTION DESCRIPTION
Light fittings are built according to common electrical engineering rules. The product meets the essential
requirements of the Directives and the harmonized standards listed in the EU Declaration of Conformity.
Used solutions and materials, electrical equipment and proper insulating spaces makes that during
normal exploitation there is no possibility any sparks, electrostatic charge, dangerous heating or light
fitting destruction caused by environment factors occurrence.

Edition: 1.0 tel: [phone], fax: [phone]
Light fittings are built as a one chamber equipment. Housing, endcaps and mounting tray are made of
aluminum. Sealing is made of silicone.
Used terminals ensures safe and non-sparking connection of inner wires and admission cables. The
diffuser is made of UV resistant polycarbonate (PC), PMMA or tempered glass.
5. PRELIMINAIRES

6. LIGHT FITTING MOUNTING
The EXL400LED luminaire should be fixed directly to the ceiling with screws. The size of the mounting
holes is Ø6mm. The spacing is adjustable by positioning the brackets.
7. ELECTRICAL CONNECTION
Installation and electrical connection should be in accordance with the requirements of PN-EN
60079-14.
To connect power supply:
•enter the power cable to the housing through the cable entry (gland),
•carefully unisolate the wires (8-10mm), and put it into the connector according to a label inside
the light fitting,
•precisely tighten power cable in the gland with two wrench,
•check the effectiveness of grounding.

Remark:
•Use one wrench to tighten the sealing nut, while using the second wrench to block gland body
against rotation, otherwise damage of the sealing can be caused and therefore sealing level
will be decreased.
8. CONDITIONS OF SAFETY USE
•Every light fitting must have label with rating data on it. Each light fitting is equipped with this
„Installation and maintenance manual”, which must be kept by user until the end of exploitation.
•Light fittings are designed for fixed installations only.
•Using light fitting outside the designated operating temperature range is unacceptable and will
decrease a lifetime of light fitting and/or damage it. It will also cause a loss of warranty.
Remark: Using light fitting beyond the designated operating temperature range may result in
the loss of explosion protection measures, such as exceed temperature class and explosion.
•Each light fitting must have a warning sign: „DO NOT OPEN UNDER VOLTAGE” on it.
•Admission cables must have 2-wires (without PE wire) and diameter 7-13mm
•Use power wires with cross section 1-2,5mm2.
•Maximum cross current I=16A.
•Depending on the version, the diffuser is made of tempered glass, PMMA or PC. Versions with
PC or PMMA diffusers should not be exposed to chemicals that can damage them, in particular:
oil, acetone, chlorine, ethyl, ether, solvents. If there is uncertainty about the substances present
in the luminaire's work area that could lead to damage to any of the components, then
determination measures should be taken. Luminaires fitted with a PC or PMMA diffuser shall
carry the warning label "Caution! Risk of electrostatic charge" (see point 11).
•Do not stare into working light source.
•Risk of electrical shock.
9. LIGHT FITTING MAINTENANCE AND SERVICING
REMARK: during the servicing and maintenance touching the LED are prohibited, because it will
decrease the lifetime of light fitting and cause the loss of manufacturer’s warranty.
It is recommended to carry out inspections of electrical equipment in accordance with the
requirements of PN-EN 60079-17.
INSPECTION: at least once a month. Inspection is made without opening the light fitting. User must
check admission cables condition (insulation damage, cracks, burns etc.). Cables must not have any
acute bends. Outside parts of the light fitting must be checked. No cracks or corrosion signs may occur.
Bolts used to mount light fitting should be properly tightened, washers mustn’t be cracked. Cleanliness
of outer surfaces and light fittings surroundings must be checked. Light fittings may not be soiled by
