zalux 52-1456/Z Explosion Proof LED Luminaire

Introduction

The subject of this manual is an explosion-proof energy-saving luminaire type OREX 1 Ex with a power of up to 160W, equipped with LED diodes of high luminous efficiency.

Intended use

The OREX 1 Ex luminaire is designed to illuminate, among others:

• industrial halls and spaces classified as zones 1, 2, 21 and 22 of the explosion hazard of dust, gases, vapors and mists of flammable liquids,
• auxiliary rooms with high dustiness with the possibility of splashes of water, i.e. boiler rooms, hydro junctions, baths, garages, shelters, warehouses in open and closed areas,
• workstation process lines, among others: chemical, petroleum, petrochemical, gas and wood industries, processing of loose mine, construction and food materials,
• places with increased temperature.

Functional properties
A wide range of power allows the luminaire to be used in high, medium and low buildings. Possible optional additional increase in energy efficiency by means of external control via the 1-10.

Design

The OREX 1 Ex luminaire consists of the following components:

• body – aluminum alloy,
• cover – aluminum alloy,
• pressure ring – aluminum alloy,
• tempered glass,
• LED light module,
• as standard, the luminaire has two Ø20mm holes with an M20x1.5 cable gland and an M20 plug. Other configurations depends on versions.
• pass-through terminals enabling the use of wires from 1mm2 to 4mm2 – possible ways of electrical connection of the luminaire presented in annex 2
• mounting eyelet,
• luminous flux adjustment via 1-10V according to versions.

Advantages of the luminaire

• robust and compact design,
• quick, simple and easy installation,
• high resistance to a corrosive industrial environment,
• very high luminous efficacy,
• high-quality power supply unit and LEDs,
• very high protection IP66/67,
• UV-resistant.

Operation, service and use

Turning on the power causes the luminaire to light up automatically. The variants equipped with a control connector (DIMMING) have the option of adjusting the output power in the range from 10% to 100% of the nominal power.

Installation, mounting, disassembling

Note!
Installation of the device should be carried out by an installer, professional fitter having the necessary knowledge, tools and qualifications, taking into account all the recommendations of this manual.
Electrical installation
The luminaire is equipped with an integrated connection chamber enabling the implementa-tion of power supply: pass-through, end or connecting the luminaire to the power line and controlling the brightness (dimming). The power cables (and the optional brightness control cables) should be led into the chamber through cable inlets and connected to the terminal strip. The diagram of the electri-cal connection for all the above-mentioned variants is presented in figure 2. Due to the anti-explosion construction, the diameter of the power and brightness control wires must be selected in accordance with point 3 of these operating instructions. The electrical connection must be made in a way that prevents accidental sliding of wires from the terminal strip or short- circuit of isolated parts of wires.
As standard, the luminaire is equipped with one M20x1.5 cable gland (made of plastic) and a blind Ø20 hole, to which an additional cable gland can be mounted. The list of cable gland approved for use in the luminaire can be found in point 8.2. On request, it is possible to install other cable gland units and / or make holes for the cable gland of a different diameter.
The outer diameter of the power cables must be compatible with the throttling range of the cable glands used. Additionally, special attention should be paid to the correctness of tightening the cable gland.

Mechanical assembly
As standard, the luminaire is adapted for pendant mounting on a cable. Optionally, with the use of additional accessories, the luminaire can be mounted, for example, to the surface of a wall, pipe / mast.
If mounting accessory is disassembled for transport, at the assembly stage, fix it using the included screws and spring washers.
It is possible to order the luminaire without mounting accessories, then proper mounting of the luminaire should be ensured. The elements used for fixing the fittings (adapters, lugs) should be properly secured against loosening, eg with thread glue, spring washers, self-locking nuts, etc. Fixing the fitting should take the entire load so that the power cable is not stressed.
In the case of installation in the proximity of machines or devices that may cause excessive heating of the luminaire, the use of additional thermal shields should be considered.
Using the luminaire in a place exposed to direct sunlight may cause excessive heating of the luminaire, which may reduce its lifetime and even damage it. It is recommended that the luminaire installed in such places is turned off during the day.

Maintenance and repairs

Observe the laws and regulations in your country/workplace when using the lamp.
During periodic inspections, check:

• Correctness of tightening of power cables in cable gland units;
• Correct installation of wires in the terminal strip; Unused clamps must be tightened.
• Check the housing for mechanical damage;
• Check the technical condition of the gaskets, especially the cover gaskets;
• Condition of the paint coat, especially when using a C5 category paint coat (on request);

In the event of heavy soiling, the luminaire should be cleaned with a damp cloth.
In the case of using a luminaire with a special paint coating in category C5, a coating control plan should be introduced in accordance with EN ISO 12944-8. The control plan is adapted to the specific operating conditions of the luminaire. It should contain a description of the control tasks and the scope of the work performed. The coating corrosion assessment should be made on the basis of the ISO 4628 standard. Failure to follow the above procedure may result in the loss of the paint coat-ing warranty.
The lifetime of the light source depends on the ambient temperature of the luminaire and its power. During operation, LEDs gradually reduce their luminous flux – this is a natural process, charac-teristic of all white LEDs. The degree of LED wear does not affect the luminaire’s operational safety.

• Due to the explosion-proof design, service repairs are made to the device (apart from replacement of spare parts mentioned in this manual) may only be performed by the manufacturer’s service or a unit by him authorized person with appropriate service documentation.
• Before opening the housing, disconnect the power supply.
• It is forbidden to open the luminaire while it is energized. After turning off the power, wait 30 minutes before opening the fixture.
• In case of dirt clean the luminaire only with a damp cloth.
• When replacing the power supply unit, pay special attention to the correct electrical connection with the LED matrix
