2. Installation instruction
This Installation instruction document contains both general and specific information on how to carry
out the installation of the AWC 500 system. By observing the advice given in this document, a safe
and correct installation of the AWC 500 system is ensured.
The Installation instruction consist of three parts:
• A System installation, which contains general precautions that should be observed during
installation
• Information on How to wire the individual hardware modules
• and Replacement instructions
3. System installation
The system installation consists of the following four main parts:
• Pre-installation considerations regarding the AWC 500 system
• Installation of the Rack in the cabinet
• Connecting power supply to the Rack
• Establishing the network communication
3.1. Precautions regarding the ambient temperature of the AWC
500 system
The ambient temperature T
AMB
as seen from the perspective of the AWC 500 (that is; T
AMB
is the
temperature within the control cabinet) has a decisive influence on the minimum expected lifetime for
the electronic circuits in the rack.
Table 1. Expected life time
AMBIENT TEMPERATURE MIN. EXPECTED LIFETIME
T
AMB
< 40 °C 20 years
3.2. Installing the Rack
The AWC 500 rack is available in different sizes - Rack5·0 (TE 12), Rack5·1 (TE 18), Rack5·2 (TE
24), Rack5·3 (TE 30), Rack5·5 (TE 42) and a Rack5·8 (TE 60) rack. See the Figure 1 and Table 2 for
dimensions for each of the racks.
During installation of the Rack observance of the practical precautions show in Figure 2 is necessary
in order to avoid problems regarding free space in front of the rack as well as cooling.
During operation, the connectors must be clear of the front door of the cabinet. The recommended
distance from the mounting plate of the cabinet to the inside of the closed cabinet door must be larger
than the specified "A" measure in Figure 2.
Furthermore, the distance from the mounting plate of the cabinet to any fixed objects in front of the
rack (with an open cabinet door) should as a minimum be the specified "B" measure in Figure 2. This
is necessary in order to ensure sufficient working space for replacing and inspection of the AWC 500
hardware modules.

3.3. Recommended screws/bolts for mounting
It is recommended to mount the AWC 500 using a stainless steel M6 screw/bolt and matching plain
washer of A2-70 ISO 3506 quality or better. The screw/bolt should be tightened with 5 Nm.
3.4. Grounding the Rack
When mounting the Rack it is very important to make sure that the metal rack frame gets a solid
electrical connection with the presumed grounded cabinet. A firmly grounded Rack is important both
AWC 500 Installation instruction 3.3. Recommended screws/bolts for mounting

Page 7
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.

4.1.1. Power input
The PCM/PDM provides a galvanic insulation between the power source and the AWC 500 system.
The PCM/PDM is equipped with a switch mode power supply, which generates supply voltage for the
control part of the PCM and for supply voltages to the other modules.
The PCM/PDM has a build-in 20 ms (minimum) power blackout protection. This feature assures that if
the power suddenly drops to below the minimum threshold the complete AWC 500 system; including
all IO module within the rack; will continue to operate as normal. If power returns within this 50 ms
period the AWC 500 system will continue un-interrupted. If power continues to be absent after this
blackout protection period the AWC 500 will enter its Safe Shutdown Cycle in which it will assure that
all data addressed to the non-volatile memory is securely written.
The PDM offers two redundant and prioritized power inputs. The PDM will always source its power
from the primary input (`Pri') until this drop below its operating threshold in which case the PDM;
without interruption; will switch to the secondary input (`Sec').
The total power consumption of the PCM/PDM depends on the configuration in the rack, as the
modules have different power consumption.
Supply voltage: 18…36 V An external fuse of 4…10 A is recommended.

The PCM/PDM offers different features to interconnect AWC 500 racks or to connect third party
EtherCAT components.
All PCM/PDM modules offer two EtherCAT OUT ports (Port 1 and Port 2). These are used to connect
directly to other distributed AWC 500 racks with PDM modules or to third party EtherCAT components.
The PDM module additionally offers one EtherCAT IN port (Port 0). The ports are either 100Base-TX
(twisted-pair) or 100Base-FX (Fibre). Table 4 shows which modules offer which interfaces.

5. Module replacement instructions
5.1. General precautions
Before handling the boards there are a few, but important instructions that must be observed:
Throughout the whole process of manufacturing and testing, the products have been kept in static
shielding bags, and all personnel handling the products have been protected against static electricity
and the subsequent ESD (electrostatic discharge).
Consequently, we ask you to observe certain rules when handling our products - otherwise our efforts
may be wasted:
Be sure to carry a connection to earth when handling our PCBs. If the correct equipment (bracelet, IC
tongs) is not available, you must improvise. You may e.g. place an open wire under your watch and
connect this to earth via a heavy resistor (1 MΩ). As to earth connection, it should be possible to use
the rack frame or the cabinet. Note that the limit for registration of static electricity for a human being is
considerably higher than the limit above which electronics and electronic components are damaged.
BE AWARE OF STATIC ELECTRICITY WHEN HANDLING!
5.2. Handling of modules
Each module is fastened to the rack with M2.5 Pozidriv® collar screws. These should be loosened
before the extraction handles are used to lift the module free of the rack. When remounting the
modules the M2.5 Pozidriv® collar screws must be tightened with 0.7…0.8 Nm to assure the products
robustness towards vibration as well as shocks.
5.3. Adding/replacing mSATA cards on the PCM5·2 module
The PCM5·2 module has a mSATA card slot placed inaccessible from the outside. This placement is
to prevent disruption of operation of the card during production. Adding/replacement of the mSATA
module is done by removing the PCM5·2 module from the racks as described above.
Figure 3. mSATA expansion slot
5.4. Replacing the RTC Battery on the PCM5·2 module
The PCM5·2 has a lithium battery for maintaining the real-time clock, when not power is applied. The
life time of the battery is 10 years, thus the battery needs to be replaced on scheduled basis.
