1.1 About this guide

1.2 M Series – modular construction

This guide has been prepared to help the luminaire designers and manufacturers in the process of designing Helvar M Series modules into the luminaires and also to give mechanical and electrical guidelines for the luminaire assembly.

The M Series has slim linear design with the width of only 18 mm and two available lengths: 280 mm and 560 mm. By offering multiple lenghts and versions, you can build linear luminaires of different lengths and specifications for various applications.

When connecting M282A and M562A modules together, series connection is recommended.

When connecting M282B/C and M562B/C modules together, parallel connection is recommended, or optionally series connection of sections with such combinations that the topology of each section is equivalent(e.g. 2 x M282B in parallel <-> 1 x M562B).

3 LED module system design3.1 Electrical design, electrical safety

During the design it is luminaire manufacturer’s responsibility to follow the international and national electrical design regulations and recommendations for the electrical safety and luminaire protection. Electrical safety classification and protection class is depending on:

1. Actual luminaire design and safety classification

• According to standard IEC / EN 60598-1

2. LED driver insulation between live parts and touchable parts

• Basic insulation or double insulation

3. LED driver output isolation (galvanic isolation)

• When SELV < 60 V, both SELV poles can be accessible

• When SELV < 120 V, one of the SELV poles must be insulated from accidental contact

• When non-SELV, both poles must be insulated from accidental contact

3.2 Terminology

ELV, EXTRA LOW VOLTAGE• Voltage which does not exceed 50 V AC RMS or 120 V ripple free DC between conductors or between any conductor

and earth

SELV, SAFETY EXTRA LOW VOLTAGE• ELV in a circuit which is isolated from the mains supply by insulation not less than that between the primary and

secondary circuits of a safety isolating transformer

LIMITATION OF LIABILITY. ALWAYS CHECK AND FOLLOW EXACT REGULATIONS FROM LATEST RELEVANT IEC/EN STANDARDS.

3 LED module system design3.3 Construction of CLASS I luminaireLuminaires with:

1) basic insulation between live electrical parts and touchable parts of the luminaire body and

2) protective earth.

Electrically conductive casing components are connected via a protective conductor system which is at earth potential. Protective earth (PE) conducts in such a way that touchable parts can’t become live in case of the basic insulation fails. These luminaires are classified as Class I.

3.4 Construction of CLASS II luminaireLuminaires with no protective earth conductor and where the accessible conductive parts of the luminaire are separated from the live parts by double or reinforced insulation.

4.1 LEDesign™

To ease up the driver selection Helvar has developed the LEDesign™ calculating tool to assist LED specialists inselecting the appropriate control gear for LED light sources. Based on the chosen LED modules, whether Helvar LED modules or then custom ones, LEDesign™ will automatically recommend Helvar’s compatible drivers for that load. The LEDesign™ calculator is free to use and available on the Helvar website as online web version, just go to ledesign.helvar.com/

4.2 Controlling LED module solutions

The high quality dimmable DALI drivers ensure reliable and smooth dimming of the LED modules. Helvar’s LED drivers are complemented by a full and compatible range of Helvar controls and sensor solutions, suitable for both luminaire based or standalone applications (easySwitch™, iDim smart solutions) and networked applications (DIGIDIM, Imagine).

3.5 Construction of CLASS III (SELV) luminaireLuminaires in protection class III (SELV) protection against electric shock relies on supply at safety extra-low voltage (SELV).• Only LED drivers providing SELV output in independent use / remote installation• If LED module is accessible and SELV output poles touchable, driver must be SELV < 60 Vdc• If at least one of the SELV poles is not accessible, driver can be SELV <120 Vdc
