The above table also shows the maximum voltages at which
the sounders can be operated.
9) Cable Selection
Cables must be capable of handling the current drawn from
all of the units on the line.
SAFETY WARNING: If the high output BExDS120D sounders
are used at high ambient temperatures, i.e. over +40ºC, then
the cable entry temperature may exceed +70ºC and therefore
suitable heat resisting cables must be used, with a rated
service temperature of at least 95ºC.
10) Earthing
Both AC and DC sounder units must be connected to a good
quality earth. The units are provided with internal and
external-earthing terminals, which are, both located on the
terminal chamber section of the unit (see figures 2 and 3).
When using the external earth terminal a cable crimp lug
must be used. The cable lug should be located between the
two M5 stainless steel flat washers. The M5 stainless steel
spring washer must be fixed between the outer flat washer
and the M5 stainless steel nut to ensure that the cable lug is
secured against loosening and twisting.
11) Cable Glands
The sounders have dual cable gland entries with M20 x1.5
entry threads. Only cable glands approved for Ex 'd'
applications can be used, which must be suitable for the type
of cable being used and also meet the requirements of the Ex
'd' flameproof installation standard BS EN 60079-14 : 1997.
When only one cable entry is used the other one must be
closed with an Ex 'd' flameproof blanking plug, which must be
suitably approved for the installation requirements.
For combustible dust applications, the cable entry device and
blanking elements shall be in type of explosion protection
increased safety "e" or flameproof enclosure "d" and shall
have an IP 6X rating according to EN 60529.
SAFETY WARNING: If the high output BExDS120D sounders
are used at high ambient temperatures, i.e. over +40ºC, then
the cable entry temperature may exceed +70ºC and therefore
suitable heat resisting cable glands must be used, with a
rated service temperature of at least 95ºC.

End of Line Monitoring (DC Units)
15)
On BExDS120D and BExDS110D DC units, dc reverse line
monitoring can be used if required. All DC sounders have a
blocking diode fitted in their supply input lines. An end of line
monitoring diode or an end of line monitoring resistor can be
connected across the +ve and –ve terminals. If an end of line
resistor is used it must have a minimum resistance value of
3k3 ohms and a minimum wattage of 0.5 watts or a minimum
resistance value of 500 ohms and a min. wattage of 2 watts.
