AWC 500 Installation instruction
with a view to crew/operator safety precautions, and also in order to form a complete grounded metal
cage, which is part of the approved EMC.
3.5. Ensuring the AWC 500 system's electromagnetic
compatibility (EMC)
The AWC 500 system is CE marked. In short, this means that the AWC 500 system's electrical noise
immission and emission have been examined and found to comply with the EN for electromagnetic
compatibility (EMC).
A Rack correctly configured with hardware modules and cover plates, thus forming a complete
grounded metal cage, is an important part of the approved EMC. In order to ensure an intact EMC, the
rack frame and the metal front covers must be in a solid electrical connection.
Hence if modules have been out of the rack it is recommended to assure that they all
are firmly mounted in the rack frame. This is done by tightening all screws in the front
covers with 0.7...0.8 Nm.
3.6. Connecting the power supply
The AWC 500 system requires 18...36 V (incl. ripple voltage) at the supply terminals on either the
PCM5·2 or PDM5·1 modules.
To maintain operation and protection of the turbine, the AWC 500 must be secured to have power
supply although the main power supply is faulty. The PDM5·1 supports sourcing from two separate
power supplies (a Main Power Supply and a Reserve Power Supply).
3.7. Establishing the network communication
Please refer to the AWC 500 Getting started document for network configuration.
4. How to wire
Please refer to the AWC 500 datasheet for wiring diagrams on specific module.
4.1. PCM5·2/PDM5·1 module
The Power and Control Module (PCM) is the main processing module and supplies the other AWC
500 modules within the Rack with power. Furthermore the PCM in used to connect to distributed racks.
The Power and Distributed communication Module (PDM) in used is distributed racks to supply the
other AWC 500 modules within the rack with power. The module can also be used to connect to further
distributed racks.
