3 INSTALLATION
3.1 Device installation
Install the obstruction light to selected mounting point using quality-made fasteners. Level the light using a
spirit level (bubble level) if necessary. Tighten bolts and nuts. The light has 6 holes for M8 bolts on the
mounting plate. Photocell is located on top of the light under the glass and should have an uninterrupted
view of the sky to work correctly. There are two different size cable glands used on the device: M25 cable
glands for 6-17 mm cable diameter and M20 cable glands for 6-12 mm cable diameter. Make sure that all
unused glands or gland holes are sealed.
3.2 Wiring
Route cables using cable glands on back of the light head. Connect power cable wires securely to Power IN
terminal block connector. Power OUT terminal can be used to distribute power to the next light head.
Connect Modbus/RS-485 cable wires to Modbus/RS-485 IN/OUT connector. Use the same connector to
distribute data signals to next light head. Connect alarm relay cable wires to alarm relay connector. Lights
are easy to chain using lights' internal connectors.
