Installation

Installation

The device is not dependent on location or position. The device is designed to fit on 35mm DIN­ rails (EN 50022) or to be installed with a front installation frame. To remove the meter from a DIN ­rail just pull the spring loaded bolt on the underside.

The cabling for the current transformer should be held as short as possible. In case of significant measurement errors after Installation, please consider the following points:

  • The use of Rogowski ­coils as current transformers for the converter counter is discouraged because of the multiple current / voltage transformation and external amplifiers. Each transformation adds a multiplicative error on the measurement.

  • Energy Direction (current transformer) : If all currents are expected to be positive (import measurement) but one or several currents are negative, please check the correct installation of your current­ transformers as they have been wrongfully installed.

  • Transformer Ratio (current transformer) : The transformer ratios on the meter must be the same as the ones of the installed current / voltage transformers.

  • Correct Phase assignment: Current L1 and Voltage L1 must be connected to the same measurement system. See Connection Diagram.

Nonobservance of mounting and installation instructions may lead to damage or destruction of this meter.
