7.3 Connection to the house wiring
First fit the power flow direction sensor(s) into the house wiring. Take note of the following in this respect:
•
The power flow direction sensor has its input (coming from the mains) at the top and its output (going towards
the house) at the bottom (on power flow direction sensor 3, the device is simply rotated by 180° on installation
so that the input and output are swapped – the device is fitted upside-down).
•
The sequence of neutral conductor and phases on connection of the power flow direction sensor is (left to right):
N>L1>L2>L3.
•
Power flow direction sensor 1 is fitted after the electricity supply company’s meter and before the 3-pin miniature
circuit breaker (3 x 16 A).
•
The power flow direction sensor may not be fitted in the top, sealed part of the meter cabinet.
•
Make sure that the phases are identical.
•
The SENEC.Home Li is connected like any consumer.
•
The short original data cable on the power flow direction sensor(s) may not be removed, but only extended
using a Cat.6 STP Snap-In metal modular adapter. The colour of the extension cable used for this must be the
same as that of the cable to be extended.
Neutral conductor
Phase 1 - from mains connection
Phase 2 - from mains connection
Phase 3 - from mains connection
Phase 1 - to SENEC.Home Li/house/PV inverter
Phase 2 - to SENEC.Home Li/house/PV inverter
Phase 3 - to SENEC.Home Li/house/PV inverter
37 (blue) - connected to GND
36 (orange) - connected to RS485 B
35 (white) - connected to RS485 A
