Coupling device CD1000-2 Product description The CD1000-2 can be employed with an NGR monitor in HRG installations with a system voltage Ull up to 1000 V (Ungr < 600 V). It can be used at maximally 5000 m AMSL. • The coupling device is suitable for HRG applications up to AC 1000 V and/or DC 690 V. The duty time is unlimited. To provide the necessary cooling at a voltage of Ull > 690 V (Ungr > 400 V), the CD1000-2 should be mounted on a grounded metal plate of at least 300 x 300 mm. Ordering details • Coupling device for NGRM • Range of use up to AC 1000 V/DC 600 V system voltage Dimension diagram...

Wiring diagrams Wiring diagram Internal wiring diagram CD1000-2 Cable: i So that the connection between NGR and star point is also monitored, the „N“ terminal of the CDI000-2 should be connected directly to the star point of the transformer. A direct connection between the „N“ connections of the CD1000-2 and the NGR is not recommended, as in this case a line interruption between the star point and the NGR connection „N“ would not be monitored.
