Technical data Energy meter
Important information
about the measuring limits of the electrical energy meter:
1. If the effective power value is available as kW only, then cos phi must be observed.
2. The consumer load must lie within the specified power limits.
3. As the power consumption of heat pumps with frequency converters (inverters) is not sinusoidal,
there is a risk of over control of the measuring movement resulting in a measurement error. The
actual peak current must never exceed 70 A for 50 A current transformers, 140 A for 100 A cur-
rent transformers and 430 A for 400 A current transformers.
Connections VT1 and DI1 (= input 7) and VT2 and DI2 (= input 8) cannot be used at the same time
(e.g. the use of VT1 and DI2 is possible).Subject to technical modifications as well as typographical
and printing errors. This manual is only valid for devices with the corresponding firmware version.
