Instructions for use

Application
Recessed location luminaire for installation in gravel, lawns, flower beds, or in compacted surfaces. Drive-over luminaire for vehicles with pneumatic tyres.
Please note: Luminaire must not be used for installations in road lanes, where the fixture is exposed to a horizontal strain due to braking, acceleration and change of direction. The minimum distance to illuminated objects above the light distribution opening must be ü 0.5 m +. For walk- through public areas, we recommend skid-blocking glass – see accessories.

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.

Installation

Luminaire for recessed mounting in gravel, lawns and flower beds. The recessed depth must be arranged such that the trim ring is above ground level.
When installed in compacted surfaces make sure that the housing is firmly fixed and that the trim ring is not directly resting on the pavement or other surfaces (Fig. A).

For this purpose installation housing 70 688 can be practical (Fig. B).

The electrical connection must be carried out with matching protection class and safety class with suitable connection terminals (not included in the scope of delivery) at the luminaire power supply cable. We recommend to use a BEGA distribution box 70 730 or 71 053. To protect the luminaire power supply cable against mechanical damage, push the included installation pipe over the cable.
Tighten the screws in the trim ring evenly crosswise.
Torque = 5Nm.

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. LED are high-quality electronic components! Please avoid touching the light output opening of the LED directly during relamping. 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 cleaners. The luminaire housing must be completely clean and absolutely dry. Please follow the installation instructions for the LED module. Check all screws and threads thoroughly and grease them. Check the gasket and replace, if necessary. A broken glass must be replaced. Insert glass with gasket – with stepped side turned upward and the groove structure of the gasket turned downward – into the luminaire housing. Make sure that the glass is correctly positioned in the gasket bed.
Place trim ring onto glass step and tighten screws crosswise.
