Overvoltage protection

The electronic components installed in the luminaire are protected against overvoltage in accordance with DIN EN 61547. To achieve an additional protection against e.g. transients, etc. we recommend separate overvoltage protection components. You can find them on our website at www.bega.com.

Safety

The installation and operation of this luminaire are subject to national safety regulations. Installation and commissioning may only be carried out by a qualified electrician. We recommend fuse protection via a residual current circuit breaker to be provided by the customer.

The manufacturer accepts no liability for damage caused by improper use or installation. If subsequent modifications are made to the luminaire, the person responsible for these modifications shall be considered the manufacturer.

Notice prior to installation:

To accept the maximum pressure load of 2,000 kg (~20 kN) a proper foundation must be provided by the customer.

The pressure load is transferred to the foundation by this luminaire housing provided at site.

The foundation must be carried out on firm subgrade.

In order to obtain a firm stableness, the luminaire housing must be firmly concreted in.

Installation

Position luminaire housing on the foundation (as described above) and fix it with enclosed or any other suitable fixing material.

The electrical connection at the luminaire connecting cable must be carried out on site according to the protection class and safety class.

We recommend to use a distribution box

70 730-.

To protect the luminaire connecting cable from damage push the enclosed cable conduit over the cable.

After finishing the ground works remove protection film from the luminaire cover.

Tighten the screws in the trim ring evenly crosswise.

Torque = 3Nm.

Please note:

Do not remove the desiccant bag from the luminaire housing.

It is needed to remove residual moisture.

Cleaning · Maintenance

After installation, the luminaire should first be cleaned. Building dust, residues from contact adhesives, paint splashes and rust film must be completely removed. Never use high pressure cleaners and cleaning implements made of normal steel, steel brushes or steel wool because they cause extraneous rust to form. When using stainless steel cleaners, please read the directions carefully.

Cleaning agents containing hydrochloric acid and chlorides should never be used.

We recommend cleaning the luminaires regularly

Replacing the LED module

The designation of the LED module is noted on a label in the luminaire.

The light colour and light output of BEGA replacement modules correspond to those of the modules originally fitted. The module can be replaced by qualified persons using standard tools.

Disconnect the electrical installation. Clean dirt and deposits from key openings of screw head. Do not use a high pressure cleaner. Open the luminaire and clean. Use only solvent-free cleansers. Dismantle the LED-board unit and disconnect the connecting cable at the terminal of the LED board unit. Make electrical connection of the new LED board unit.

Fix LED board unit in the luminaire housing.

Check all screws and threads thoroughly and grease. Check the gasket and replace, if necessary. The luminaire housing must be completely clean and absolutely dry. Close the luminaire. Torque = 3 Nm. Chemicals which have a corroding effect must not affect the luminaire housing.

Accessories

70 730 Distribution box

The distribution box is meant for installation in the soil and allows a junction from the supply cable to the luminaire and through-wiring to the next luminaire.

After the electrical connection the distribution box is filled up with gel and closed.
