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 (L, PE, N) in standard connection and (L1, PE, N) in 3 phase connection,
•the wires L2, L3 in 3 phase connection are only a through connection,
•precisely tighten power cable in the gland with two wrench,
•check the effectiveness of grounding.
Standard connection:

3 Phase connection:
Remarks:
•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.
•Not following this remark may cause may damage the seals, resulting in lowering of IP rating
and explosionproof security.
•If neutral line is damaged or voltage occurs in it, a floodlight or group of floodlights may start to
work under larger than predicted load, witch in consequence may lead to damage of power
delivery system.
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.
•As power cables, use 3-core cables (with PE core) or 5-core cables (with PE core) for the 3F
version.

Release date: 10.05.2023 ul. Maszynowa 30A,80-298 Gdańsk,
Edition: 1.1 tel: [phone], fax: [phone]
•Use power wires with cross section 1-4mm2. Cross-section 1-6mm2 for special luminaire
execution.
•Maximum cross current I=16A. For 3 phase connection cross current I=10A
•Depending on the version, the diffuser is made of tempered glass or PC. Version with PC
diffuser should not be exposed to chemicals that can damage it, 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 diffuser shall carry the warning label
"Caution! Risk of electrostatic charge".
•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
paint or grease. Do not allow for dust (dirt) deposition on the light fitting. The readability of rating and
warning plates must be checked. Abnormalities found must be fixed.
SERVICE AND MAINTENANCE: at least once a year. Service and maintenance must be made with
power supply turned off. User must make inspection steps first. After opening: metal parts painting,
condition of inner wiring and its mounting, insulating materials, cable glands gaskets, terminals.
Abnormalities found must be fixed. Rating and warning plates must be cleaned. Surfaces of insulating
materials and covers must be clean.
VERIFICATION OF TECHNICAL CONDITION: at least once for 2 years. Power supply must be
switched off. Verification of technical condition must be proceeded outside of Ex zone. Light fitting must
be uninstalled. Work of luminaire can be carried out if:
•concentration level of the explosive atmosphere does not exceed 10% of the lower explosion
limit (LEL) in the case of installation in zones 1 and 2 with explosion hazard,
•cleaning activities were carried out to ensure cleanliness of the installation (house-keeping) and
the possibility of dust cloud occurrence was excluded in the case of development in zones 21,
22 with explosion hazard.
Besides all the examination during inspection, service and maintenance paragraphs electrical
examination must be also made: light fitting current consumption, insulation examination, protective
