  • Page 5: Application

    1. APPLICATION The N43 meter,assembled on a rail, is a programmable digital instrument designed for the measurement of 3-phase, 3 or 4-wire power network parameters in balanced or unbalan- ced systems. The measured values are displayed on a dedicated LCD display. The meter enables control and optimization of the power electronic devices, systems and industrial installations.

  • Page 7: Basic Requirements, Operational Safety

    3. BASIC REQUIREMENTS, OPERATIONAL SAFETY In terms of operational safety it meets the requirements of the EN 61010-1 standard. Comments concerning safety: • The meter should be installed and connected only by a qualifi ed personnel. All relevant safety measures should be observed during installation.

  • Page 8: Installation

    /direct measurement/. The meters should not be installed on the rail in direct contact with other devices that emit heat (e.g. other N43 meters). There must be a minimum 5 mm spacing between devices in order to enable heat transfer from a housing to the environ- ment.

  • Page 10: Meter Description

    5. METER DESCRIPTION 5.1 Current inputs All current inputs are galvanically isolated (internal current transformers). The meter is adapted for direct connections /up to 63 A/ or to work with external measuring current transformers /version 1 A/5 A /. Displayed current values and derivative quan- tities are automatically converted in relation to the introduced external current transformer ratio.
