See separate Tone Selection Sheet.
8.0 Cable Gland: The SB150-1 series product has two cable gland entries. 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 EN 60079-14.
SAFETY WARNING: If the SB150-1 is used at high ambient temperatures, ie over +40
temperature may exceed +70 C and therefore suitable heat resisting cable glands must be used, with a rated
0
service temperature of at least 95 C.
0
If a high IP (Ingress Protection) rating is required, a suitable sealing washer must be fitted under the cable
gland. 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.
9.0 End of Line Monitoring: An end of line monitoring diode or an end of line monitoring resistor can be
connected across the 24v+ and 0 terminals. If an end of line monitoring resistor is used, it must have a
maximum resistance value of 3k ohms and a minimum wattage of 0.5 Watts; or a minimum resistance value of
1.2k ohms and a maximum wattage of 2 Watts.
10.0 Maintenance: Little or no maintenance is required during the normal working life of the product. The
'GRP' enclosure is resistant to most acids, alkalis and chemicals and has been designed to withstand severe
weather conditions. However it is suggested that to avoid the possibility of a potential electrostatic charge
build up, the exterior of the product is periodically wiped down with a clean damp cloth. At this point a
visual inspection is recommended to ensure that the product is in good working order and no damage has been
sustained during its normal operation.
SAFETY WARNING: In the case of Anti Static and UV Resistant GRP, the painting of the enclosure surface
has been processed specially. To maintain the product to be Anti Static, extra normal painting is not allowed.
If any failure occurs but not caused by human factor, the product can be returned to Moflash for free repair or
replacement during the warranty.
