WARNING

The warning notes for "air-cooled units" apply.

Installation and maintenance work relating to the water-equipment is only to be done when the installation is off load.

NOTE

In the case of a parallel connection, see also Section 3.7 of "air-cooled units".

CAUTION! Because the unit has been designed as a system component, the power connections have not been designed as direct connections.

The AC connections from the supply and the DC connections to the DC link must be made via suitably dimensioned copper rails (no cable, no aluminium).

The components have 3 temperature measuring points on each copper rail of the anode which is not water cooled. The highest temperature is evaluated. This temperature measurement serves as an indicator of overloading or pump failure. The thyristors of the components, however, cannot be 100 % protected in this way! The degree of success depends on the operating status of the converter and the flow rate of the coolant.

The rectifier units are delivered with semiconductor fuse for product status A2 and onwards. Option L32 means that they are delivered without semiconductor fuses.

The rectifier/regenerating units are generally operated with fuses.

The electronic p.c.b's must be supplied with power from an external 24 power supply system (1 A for basic unit, 0.3 A for every other unit connected in parallel).

A rectifier/regenerating unit consists of two converters in separate housings.

The coolant circuits of the two converters are to be connected in parallel. From product status A2 onwards (cooling boxes with a pressure drop of 0.65 bar), the two converters can be connected in series as well because they only have power losses alternately.

The electronics board is located in the rectifier unit. The firing cables, temperature sensors and fuse monitor are to be connected using the cables supplied in accordance with the general and power-circuit diagrams in Section 3.3. The regenerating unit is to be mounted to the right of the rectifier unit.
