Cooling connections
Make sure that cooling liquid runs freely in and out from the electric device.
When selecting cooling liquid nipples, choose nipples that can resist galvanic corrosion.
To prevent damage to the cooling connectors, refer to the documentation of the manufacturer for the correct tightening
torque of the cooling liquid nipples.
Connect the electric device directly to the cooling circuit.
Make sure that the coolant ow is equal or higher than rated and the coolant temperature at
the inlet of the electric device is lower or equal to the rated temperature.
For more information, see Chapter
and product data sheets. Rated
values can be found on the rating plate of the electric device.
It is recommended to x the hose on the coolant connection with a hose clamp or a hose clip
after the protection cap has been removed.
Use water/glycol mix or pure water with corrosion inhibitor as the coolant.
Recommended coolants
Ethylene glycol is a toxic compound. Avoid exposure to the coolant. Handle with care. Use appropriate personal
protective equipment when you handle the coolant.
The electric device works correctly with water based coolant. Plain water with appropriate
corrosive inhibitor is acceptable, for example water with maximum of 50% glycol coolant. Ethylene
glycol based Glysantin
®
G48
®
(includes also corrosion inhibitors) or similar can be used. Propylene
glycol based coolants, like Splash
®
RV&Marine antifreeze, can also be used. Propylene glycol is
relatively safe compound for humans and the environment.
