CAUTION
Damage to property through inappropriate or insufficient cooling of
the thyristor power units!
Water-cooled thyristor power units may only be operated when the
cooling water circuit is active! Condensation on water-carrying com-
ponents must be prevented.
Damage to property through insufficient water quality in the cooling
water circuit!
Deposits in the cooling system may reduce the water flow, thus im-
pairing the performance of the cooling system with time.
Therefore, you should ensure that your cooling water has the follow-
ing properties:
D pH value
D Degree of hardness D
(1 German degree = 1.25 British degrees = 1.05 US degrees =
1.8 French degrees)
D Chlorides
D Nitrates
D Sulfates
D Insoluble substances
Tap water usually meets these requirements. However, an algicide
should be added.
Make sure that all contact surfaces are bright, i.e. free of paint, plastic coat-
L
ing or dirt/oxidation.
Mount the device in a vertical position.
