SIMOVERT MASTERDRIVES Operating Instructions 13-13
13.1.1 Notes regarding installation and components
A closed-circuit water-cooling system of stainless steel with water/water
heat exchanger is recommended for the converters.
To prevent electrochemical corrosion and transfer of vibration,
SIMOVERT MASTERDRIVES are to be connected to water supply
and return lines by flexible, electrically non-conducting hose. The
hose length (in total) should be > 1.5 m.
If plastic piping is used in the installation, this hose is not necessary.
The water hoses should be connected up before the converter is
installed.
If hose clips are used, they should be checked for tightness at three-
monthly intervals.

Fig. 13-3 Water-to-water heat exchanger
If a water supply system is already available in the plant which does not
exceed temperatures above 35 °C but does not fulfil the cooling water
requirements, the two cooling systems can be connected using a water-
water heat exchanger.
The coolers of the frequency converters are connected via a manifold
so that the necessary flow rate is ensured but the pressure does not
exceed the permitted value. Factors such as height differences and
distances must be taken into account.
For devices without anti-freeze, we recommend using VARIDOSTOP
available from Schilling Chemie. VARIDOSTOP is an organic corrosion
inhibitor specially developed for semi-open and closed cooling systems.
It protects metals against corrosion by forming a protective organic film
on the surface of the metal.
