32 A 2-Ways Single Phase active power energy meter with Serial Modbus interface, Fig. 1
Description
Energy meter with serial Modbus interface (RS-485)
enables the reading of all relevant data like consump-
tion, current, voltage, power (active and reactive). The
reactive power (idle power) can only be read on the
Modbus interface.

Notes before connecting
In order to avoid moisture in the meter due to condensate
build-up, acclimatise the meter at room temperature for
about half an hour before connecting.
Attention!
These devices must only be installed by a professional
electrician, otherwise there is the risk of fire or the risk
of an electric shock.
