The LC1x70-E-DA LED driver is suited for either in-built and independent luminaire usage. In order to have safe and reliable LED driver operation, the LED luminaires will need to comply with the relevant standards and regulations (e.g. IEC/EN 60598-1). The LED luminaire shall be designed to adequately protect the LED driver from dust, moisture and pollution. The luminaire manufacturer is responsible for the correct choice and installation of the LED drivers according to the application and product datasheets. Specifications of the LED drivers may never exceed the operating conditions as per the product datasheets.

Wiring considerations Installation & operational considerations

Wire type and cross section

• Please refer to datasheets connections & mechanical data

Wiring insulation

• According to recommendations in EN 60598

Maximum wire lengths

• Please refer to datasheets connections & mechanical data

Wire connections

• Please refer to datasheets connections diagram

Miniature Circuit Breakers (MCB)

• Type-C MCB’s with trip characteristics in according to EN 60898 are recommended.

LED driver earthing

• LED drivers are designed to support different luminaire classifications, like Class I or Class II fittings (no earth required).

Please check the individual LED driver type for its exact safety class rating.

• For Helvar LED drivers to have a reliable operation and EMC performance, the luminaires are expected to have an earth connection.

• When using a SELV-rated LED driver, then the SELV driver output has to be insulated from the luminaire earth connection (ref.

EN60598-1 luminaire standard).

Maximum tc temperature

• Reliable operation and lifetime is only guaranteed if the maximum tc point temperature is not exceeded under the conditions of use.

Strain Relief for independent use

• The LC1x70-E-DA LED driver allow use both inside the luminaire and outside the luminaire, via the LC1x70-SR strain relief. The strain relief provides reliable fastening method for the mains and

LED output wiring.

• Ensure that the LED driver does not exceed temperature higher than specified on the product datasheets.

• The general preferred installation position of LED drivers is to have the top cover facing upwards.

Current setting resistor

The Helvar LC1x70 driver platform features an adjustable constant current output.

• An external resistor can be inserted in to the current setting terminal, allowing the user to adjust the LED driver output current.

• When no external resistor is connected, then the LED drivers will operate at their default lowest current level.

• A standard through-hole resistor can be used for the current setting. To achieve the most accurate output current it is recommended to select a quality low tolerance resistor.

• For the resistor / current value selection, please refer to the enclosed table below.

Auxiliary output for cooling fan

LC1x70-E-DA driver features an auxiliary output for cooling fan

• Auxiliary output is not allowed to be used in inpendent installation

• In-built luminaire use: Check auxiliary maximum loading (cooling fan) by actual luminaire temperature measurements.
