For proper installation of the High Current it is important that you follow the next steps carefully.
Take the required safety measures and always turn off the power!
Step 1
Turn o the main power in the meter box by ipping the main fuse or by unscrewing the fuses.
Step 2
Remove the screws of the distribution board and open it.
Step 3
Decide where to place the 3 measuring current transformers that will be connected to the High Current,
and make sure they come out of the distribution board. Make sure to do this in a safe and secure manner.
Step 4
Click the measuring current transformers just before or right after the main fuse and put them on the 1st,
2nd, and 3rd phase. Make sure to install them in the same way. It doesn’t matter in what order they are placed.
Step 5
Decide where to place the High Current and attach it to the wall using the xing materials.
Step 6
Connect the cables of the measuring current
transformer to the corresponding inputs of the
High Current. See image 1 (nr. 1, 2, and 3). Make
sure they are placed the same!
Make sure to connect the 1st phase with the 1st
phase of the High Current, and do the same with
phases 2 and 3.
The High Current is suitable for a maximum of 20 supply stations and can only be installed with current
transformers which are always included. The High Current goes up to a maximum of 1000A.

Step 7
Put the data cable through the corresponding opening
and attach the 2 wires from 1 wire pair of the SF-UTP
cable in the orange/black connector as shown on image
2 and plug the connector to the corresponding RS485-
port in the High Current. See image 1 (A) on page 4.
Make sure that the 2 wires correspond with the
connected wires of the modem in the supply station.
Step 8
Connect the power in the High Current to the
corresponding connection. See image 1 (B)
on page 4. Connect the power.
Step 9
Now the LED-light on the print of the High Current
should start to ash.

The High Current is connected to the EV-Box G4 series with other connectors. This one is made for 2 instead
of 4. The wire pair is connected in the same way as the connector with 4 pins.

7Installation manual |High Current
EV-Optimizer is not responsible for calamities
resulting from incorrect installations by third parties.
First, determine whether the main fuse contains a fuse or a circuit breaker.
Now that the High Current has been installed, you can verify if the High Current
is placed in the right way. If it concerns a fuse, there should be 2 lights turned on.
If it concerns a circuit breaker, there should be 1 light turned on.
If this is not displayed correctly, it can be changed with the button next to the lights.
1 light: circuit breaker
2 lights: fuse
Now contact the supplier of the supply station to verify the connection (smart grid
connected) The High Current is now ready to be used!

Red: No connection with the EV-Box
Check the connection of the data cable! Use 1 wire pair, not 2 dierent wire pairs.
Turn the wire pair around.
Flashing green: Connection with the supply station
The ashing speed is equal to the power consumption. If the power usage goes up, the
LED indicator will ash faster.
Continuing green: The EV-Optimizer is still in programming mode
Put the rotary switch (in the EV-Optimizer) from 5 to 6 inside the EV-Optimizer.
