Seiwa SW AP03 - Manual (Page 29)

CHAPTER 3 INSTALLATION
Before proceeding with the installation, check the contents of the shipment to ensure
that all components ordered are present and undamaged. If a steering motor or
hydraulic drive is included, check that its voltage rating is suitable for the vessel's
supply. Read all of this chapter before starting and then follow this step-by-step guide:
1. Mount the Junction Box as described in Sect 3.1. Take care that the
polarity of the battery wires is correct and that the metal parts of the
terminal blocks grip the wires and not the insulation.
2. Mount the Controller as per Sect 3.2.
3. Mount the Compass as described in Sect 3.3. Take care to keep it away
from the sources of magnetic interference.
4. Mount the Rudder Transducer as shown in Sect 3.4 Ensure that the linkage
geometry is correct and if it is in a storage area, ensure that heavy objects
will not fall on the linkage.
5. Install and connect any additional attachments as described in Sect 3.5.
(Or, if preferred, these could be installed after initial commissioning.)
6. Install the steering drive as described in Sect 3.6
7. Apply power to the Junction Box. Now turn to Section 2.2 of this Manual -
Getting Started - and carry out the initial setup.
3.1 JUNCTION BOX
The Junction Box should mounted on a vertical surface with the cable entry holes
facing downwards. It should be protected from the weather and be well above the bilge
water level in the vessel. Do not mount it in the engine room or other high-temperature
location. Two further considerations are that the connection sockets be easily
accessible when the lid is removed and that there is a space of at least 50mm on all
four sides to permit air circulation.

(The outer case forms a heat sink for the internal power components).
Fix the case using screws through the two mounting flanges. To open the case,
remove the four screws holding the cover flanges to the base and lift the cover.
