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. 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

Loosen the hexagon socket screws (wrench size 5mm) at the pole head and lift out the connection box. Insert the floodlight into the profile groove on the profile pole and fix it in the desired position using both hexagon socket screws (wrench size 4 mm) (see sketch A). Route the connecting cable for the floodlight into the pole through the closest slotted hole in the profile groove. The electrical connection is made in the connection box in the pole head. Guide the floodlight connecting cable through the cable gland into the connection box. Tighten the screw cable gland. Make the earth conductor connection and the electrical connection.

BEGA-84983-Gobo-Floodlight-FIG-3

Note correct configuration of the mains supply cable. The earth conductor is connected at the green-yellow (1), the phase to the brown (L), and the neutral conductor to the blue (N) marked wire. The connection of the control cables is achieved by means of the both leads marked with DALI. In case these leads are not used the luminaire will be operated at full light output. Place the connection box on the profile pole and secure it in place. Make sure that gasket is positioned correctly. Tighten the screws uniformly in crosswise fashion.

Adjust floodlight
Undo hexagon socket screw (wrench size 5 mm) and hexagon nut (wrench size 27 mm) and set the desired beam direction (see sketch B, C).

Torque

Hexagon socket screw = 7 Nm
Hexagon nut = 35 Nm
Secure bolted connection Gß against loosening by tightening the hexagon socket screws (wrench size 2 mm).

Inserting a Gobo
Open the floodlight: Turn the lens cover anticlockwise and lift off. To insert a gobo, adjust the knurled screw R4 of the gobo holder so that it is in line with the knurled screw R3 below it. Loosen the three knurled screws R3, turn the lens cylinder clockwise to the stop and lift it off. Remove the retaining ring on the Gobo receptacle and insert the Gobo. Make sure to insert the motif inverted and upside down. Align the Gobo according to the subsequent floodlight position.

Exact alignment is possible in the mounted position via knurled screw R4 within a range of ± 22.5°. Insert the retaining ring (note the locking lugs) and replace the lens cylinder, turn it clockwise as far as it will go and tighten the three knurled screws R3 hand-tight. Adjusting the Gobo motif size and focus: Switch on the floodlight. The size and focus of the Gobo motif is adjusted by moving the lens holder. Loosen the two knurled screws R1 and R2 and adjust the lens distance until the desired size is reached.

A larger lens distance will make the motif smaller, a smaller distance will make it larger. Tighten the knurled screw R1. Use the second lens to adjust optimal focus and then tighten the knurled screws R2. The shields provided (with 20 and 30mm apertures) are used to optimise the degree of illuminance and sharpness. Place the shields on the lens cylinder with the side lugs pointing outward to choose the right one.

Finally, insert the side lugs of the shield into the lens cylinder. The desiccant pouch provided in the delivery must be placed inside the luminaire to ensure max. service life of the electric components. Remove the desiccant pouch from the foil packaging and place it in the position marked by the red information label immediately before finally closing the luminaire.

Position the lens cover on the floodlight housing so that the notches in the floodlight housing and the lens cover are congruent. Screw on the lens cover clockwise until the stop. Screw in the locking pin (hexagon socket
wrench SW 2.5) on the back of the floodlight housing.

Gobo motifs
You can find a large selection of Gobo motifs or have them customised to your specifications in the corresponding Rosco standard sizes at www.castinfo.de.

Maintenance

The connecting cable must be checked for external damage and may only be replaced by a qualified electrician.

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.

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 BEGAreplacement modules correspond to those of the modules originally fitted. The module can be replaced by qualified persons using standard tools. Disconnect the system. Loosen the locking pin (hexagon socket wrench SW2.5) on the back of the floodlight housing. Turn the lens cover clockwise and lift it off. Undo the 4 mounting screws of the lens unit (Torx drive T20) and remove the complete lens unit. Replace LED module. Please follow the installation instructions for the LED module.

Replace and secure the lens unit. Switch on the floodlight, check the Gobo motif size and focus, and adjust as needed. Position the lens cover on the floodlight housing so that the notches in the floodlight housing and the lens cover are congruent. Srew on the lens cover clockwise until the stop. Screw in the locking pin.
