C.7 Coolant Connection Block at the Generator Capsule
Control of the coolant connection
block
The coolant terminal block at the side of
the generator housing must be thoroughly
checked in the case of all seawater-coo-
led generators. This coolant terminal
block is manufactured from a special alu-
minium alloy and also serves as a sacri-
ficial anode. If the aluminium alloy of the
generator is damaged by the Direct Cur-
rent, it initially affects the coolant inlet
block. If visible corrosion is identifiable
from the outside of the coolant terminal
block, then the block must be replaced at
regular intervals (at least once per year).
In this case the coolant terminal block is a wearing part. It should always be available in all cases
as a spare part on board.

Replacement of the Coolant Connection Block
A "special" sealant is used for the coolant connection block. The fixing bolts are not intended to fix
the coolant terminal block firmly to the surface area. These screws serve only to keep coolant ter-
minal block firmly secured until the sealant has hardened. The fixing bolts should only be tighte-
ned by hand.
ATTENTION! On the side, the fixing bolts must be applied with an electrically neutral fat
(e.g. anti seize). If the fixing bolts (high-grade steel) are screwed into the aluminium
threads without the grease being used, then there is a danger of corrosion, and it is possi-
ble that the thread wears out when loosening the screws.
