Safety Instructions and Warranty Terms 7

Manual econ sens+ Version 1.40

The econ sens+ energy consumption meter can be used with various public power supplies:

3-phase four-wire power system (with neutral conductor)

3-phase three-wire power system (without neutral conductor)

Single-phase power system

Fig. 7 shows the integration of the econ sens + into a 3-phase 4-wire power system.

The phases L1, L2 and L3 of the voltage path must be protected by means of automatic circuit

breakers to prevent the system from being damaged in the event of a short circuit. A B6 (max. B10)

automatic circuit breaker is recommended. For safety reasons it is preferable to use a short-circuit-

proof conductor (NSGAFÖU) in front of the circuit breakers.
