Safety Manual (AADvance Controller)
Marine Certification
AADvance has been tested and found to comply with the EMC requirements
of BS EN 60945:2002. EMC compliance within a marine environment is
dependant on and can only be assured by the use of:
 shielded Ethernet cables
 adequate bonding of the system chassis to a suitable ground reference
Fit EMC Static Protection Covers
For EMC static protection you should fit the black plastic protection covers
(supplied with the base units) over any exposed 48 pin DIN connectors on the
T9300 I/O Base unit.
Using Shielded Cabling for Ethernet and Serial Ports
When using cable lengths that exceed 3m for Ethernet and Serial
communication you must use shielded cable to remain within the emission and
immunity standards. Also ensure that the shields are grounded to the
controller chassis.
 Important: The system is resistant to radio interference due to its bus
structure. However, sensible use of site radios is advised; do not use
radios inside or near an open panel.
AADvance System Power Requirements
The AADvance controller is designed to operate from two independent 24V
dc power supplies with a common return path, that is, the 24V return shall be
common between the power feeds.
