Use the number of cores suitable for the application. A universal part numbering system appears to
have been adopted for this type of cable as follows:
16-2-2C 2 Core
16-2-3C 3 Core
16-2-4C 4 Core
16-2-6C 6 Core
16-2-8C 8 Core
(5 Core not readily available)
Note: If using 4 Core cable and interference is detected, use 2 sets of 2 Core.
Data Cable
Data cable must be used for communication connections between MMs for sequencing applications as
well as between MMs to EGAs, MMs to a DTI and DTI to BMS systems.
Communication cable should not exceed 1km.
Types of data cable that can be used:
1 Beldon 9501 for 2-core shielded cable (1 twisted pair)
2 Beldon 9502 for 4-core shielded cable (2 twisted pairs)
3 STC OS1P24
Samples are available upon request. Low voltage and data cable can be ordered directly from
Autoflame Engineering, please contact Autoflame Sales.
When using a VSD, please review the manufacturer’s guidelines on installations to prevent EMC
including the recommendations for reactors and filters.
