The resistor must be connected directly across the +ve and
-ve terminals as shown in the following drawing. Form the
resistor legs as shown in Fig. 5, remove the +ve and –ve
terminal plugs and fit the resistor across the two terminal
plugs before refitting them to the PCBA as shown in Fig. 6. A
spacing of at least 1/16” (1.58mm) must be provided through
air and over surfaces between uninsulated live parts.

11) Earthing
The unit has both internal and external earth terminals,
(please see fig 3).
Internal earthing connections should be made to the internal
earth terminal on the PCBA, (please see fig 3 for AC, fig 4 for
DC). The earth conductor should be at least equal in size and
rating to the incoming power conductors. The internal earth
bonding wire connects the PCBA earth terminal to the
internal earth terminal in the enclosure back box.
External earth connections should be made to the M5 earth
stud, using a ring crimp terminal to secure the earth
conductor to the earth stud. The external earth conductor
should be at least 4mm2 in size. The external earth crimp
ring should be located between the two M5 plain washers
provided and securely locked down with the M5 spring
washer and M5 nut.
12) Settings
12.1. Flash Rate Setting
The D2xB1LD2 beacons can produce different flash patterns
as shown in Table 1. The flash patterns are selected by
operation of the flash setting DIP switch on the PCB, Fig 6.
