INSTALLING
The current sensor module must be connected as indicated on the front label:
1.
The external power adapter is connected to the two outer terminals on the top
of the module.
Note: Polarity is important! 1 of the 2 power adapter wires has a broken white stripe. This wire is the power
adapter GND and should therefore be connected to the GND pin (right) on the module. The other wire is the
+5 Volts and should be connected to the +5V pin (left) on the module. The middle pin is not used.
2.
The current transformers (CT): Up to 3 CT heads can be connected to the module.
The connections are located at the bottom of the module, and are labelled with
L1, L2 and L3 on the front label. Each CT wire can be mounted one above the other.
Although each measuring head is provided with 2 different coloured threads,
the polarity of connection is not important.
3.
The CT's connected to L1, L2 and L3 must be connected to the first, second and third
phase of the house grid in the correct order. Arrows are shown on the CT, but direction
is not important.
4.
The powercable connection on the terminal block of the chargepoint should match
the L1, L2 and L3 in the chargepoint. For a 1 phase installed chargepoint the L1
measurement head should match the conduction which is connected to the L1 of
the terminal block.
