Master - Slave installation
If you want to distribute the load between multiple Ecotap charging points at different stations.
You must connect the Ecotap stations in a Master-Slave / Grid configuration. To do this, follow these steps:
(Please note: if you are expanding your existing network with new charging stations, please contact Ecotap to check compatibility!)
Step 1
Apply power to all charging stations so that the charging stations are online (it can take up to 5 minutes for the charging system to find an online connection and connect once the light flashes green) (Note: do NOT connect the Canbus data cables to the stations yet, this will be done later).
Step 2
Notify your Charge Point Operator of the charging point numbers that are online, indicating which station should be set as master and which charging stations should be set as slave. (Telephone number listed on the doming stickers of the charging points).
Step 3
Once the charging points have successfully received the correct master or slave settings, the Canbus data cables can be connected to the red terminals (as shown in the images below).
Step 4
As a final step, check that the master charging station and the last slave are correctly equipped with a 120 ohm resistor. All charging stations between the master and the last slave must NOT have a resistor.
Other information
Maximum of 9 slaves behind 1 master.
The recommended data cable is a Canbus cable min CAT 5.
Data cable may only be looped through (no star network).
A minimum of 13 amps per phase per charging point is recommended.
Please note that the Canbus connections on Ecotap charging stations have been changed to CAN-IN | CAN-OUT from 2024 onwards. This is compatible with the Canbus connections of older stations. Information about connecting older stations can be found in the video animation above.
