6.13.1 Instructions and measures on prevention of galvanic corrosion
Several measures must be considered when making the installation so that galvanic corrosion can be avoided as
much as possible:
• Separation of the water column (between raw water and generator) after shutdown. This can either be a stop vlave
turned by hand (Attention! The valve must be closed after each operation) or by the installation of an automatic
ventilation valve. In this case the valve opens and closes automatically.
• Connecting all components (hull outlet, generator, heat exchanger etc.) to a common potential. For this all elements
of the installation are connected by a cable (earthed).
• Strict separation of the generator from the 12 V on-board power supply, that means potential free installation of the
12 V system (generator installation und general on-board power supply).
Please find more details in the information sheet „galvanic corrosion (electrolysis)“ which you can order at Fischer
Panda free of charge.
6.14 Insulation test
ATTENTION!Once the electrical system installation is complete, a
ground insulation test must be performed as follows:
1. Switch off all on-board electrical devices.
2. Start the generator.
3. Measure the AC-voltage with a voltmeter (adjust to Volt/AC) between:
a) generator housing and AC-Control box
b) generator housing and ground.
The measured voltage must not exceed 50 mV (millivolts).
4. Once the safety systems have been installed, they must be checked. If a Leakage Current Relay has been
installed, it also has to be tested, in order to ensure that it functions properly. The individual phrases must be
checked against each other, and between phase and ground, (the single phase or 4th phase also needs to be
checked in this fashion).
5. If the generator is protected by a ground connection, then ALL electrical devices must also be connected to this
"common" ground (usually ground contacts are attached to the devices' metallic housings).
The electrical system installation must also comply with the hook-up requirements of the shore current grid.
Generally a leakage current relay is sufficient for safe electrical operation; however, this must be confirmed by the
electrical safety standard in the region where the system is attached to a main land power grid. The relay has to
meet the required safety standard regulations.
6.15 Set into operation
After the installation the generator must be brought in service. For this the „Service record and warranty registration
must be worked through and filled out by the installing technical trained person.
This document must be handed out to the owner. The owner must be instructed for the operation, maintenance and
hazards of the generator. These include the in the manual mentioned hazards and further ones, which are the result
of the specific installation and the connected components.
Note!:Send the original Service and warranty record to Fischer
Panda to get full warranty. Make a copy for your hands.
