Assembly and operating instructions Type 7E.46
65 A 2 Way three-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 consumption,
current, voltage and power (active and reactive). The
reactive power (idle power) can only be read on the
Modbus interface

Notes before connecting
1. Do not connect L1, L2 or L3 to N
2. 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.
3. N must always be connected.
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.
