Mounting instructions

Before installation

Remove the charger from its package. Do not scratch the surface of the charger after removal from the package.

When selecting installation site, take into account the following:

• The charger is suitable for indoor and outdoor use.
• In order to ensure the optimal charging performance, the charger should not be exposed to direct sunlight.
• The minimum space needed for operating and maintenance.

Cable entries

• Take the cable routing into consideration when planning the installation. The supply cable can be routed into the enclosure from the rear or bottom. Default cable routing is from the bottom.
• The M32 cable gland for the supply cable is pre-assembled on the bottom of the charger.
• If you need to open additional cable entries, you have to disassemble the charger.

Installation steps when cable routing is from alternative cable entries

1. Disassemble the charger.

2. Open the needed cable entries with a step drill bit.

3. Prepare the cable entries with suitable accessories.

4. Remove the included cable gland from the bottom and close the cable entry with a cover plug, PMR1217.32B (accessory).

5. Assemble the base and insert.

6. Assemble also the installation box cover, if electrical cables are installed in a separate session.

Wall mounting

• When selecting the installation location, make sure that the wall material is suitable and robust. The mounting surface should be flat and vertical.

Installation steps

1. Use for the wall material suitable screws.

2. Fasten the upper screw 1270 mm measured from the ground surface. The plug holder will be at a height of 1200 mm.

3. Open the installation box hatch by removing the fastening screws (2 pcs) / unlocking the hatch lock [1].

4. Remove the entire installation box cover by unscrewing the fastening screws (4 pcs) [2].

5. Hang the charger on the screw you attached to the wall.

6. Secure the charger on wall with two washers and fastening screws (not included) [3]. Be careful not to damage the fixed charging cable!

7. Pull the electrical cables approx. 150mm through the cable glands.

8. Cut the supply cable leads in suitable lengths. Leave the ground lead long enough so that if a fault occurs it is the last one that comes loose.

9. Strip the leads 11 mm and connect to the supply connectors.

10. Put the installation box cover back in right position and secure with the screws you removed.

11. Close the installation box hatch.

Power supply

The voltage and current ratings including cable sizes must comply with national regulations.
The system dimensioning must be done by a qualified electrical designer.
The default setting is TN network. If you connect the charger to an IT network, you have to change the settings for the charger accordingly.
You can change the setting with the Ensto Charger Control Application.
Please see the chapter 14. Ensto Charger Control Application on pages 22 – 23.
It is restricted to use Ensto One within 3-phase IT network as IT network configuration could
cause unbalanced overloading on supply cables that further would require specific safety margins. In case of further questions, please contact your local Ensto representative.

| The voltage between PE and N is less than 10 V.
| The PE conductor resistance is less than 3 0.
Operational check| | All the LED states/color (green, blue, red) are functioning.
• Use a car simulator.
• Create fail and charge.
• Red at bootup, green at idle, and blue while charging.
| Test the functionality of the protective device.
Ready for use| | Correct software is in use.

Ensto Charger Control Application

• The charger is ready to use after the installation is completed.
• You can control the charger and change settings with the Ensto Charger Control Application.
• In this chapter is described the installer menu in the application.
• For additional instructions please see the User Guide for the Ensto One Home charger.

Installer menu in the Ensto Charger Control Application

WARNING
Danger of electric shock! Risk of fire!

• Settings described in this chapter must only be done by an electrically skilled person.

Open the Installer menu

• Open the Ensto Charger Control on your mobile device.
• Go to “Support”.
• Press the letter E on the ENSTO logo for a long time.

Self test

• The charger performs a self test automatically at start-up.
• During the self-test, several components and their proper function is tested.
• The LED indicator is stable green during the self test.
• The extent and duration of the self test depend on the charger model.
• If a critical fault is detected during the self test, the charger will go to error state. You can see the error code in the error log.

Update device firmware
This menu is visible if a firmware update is available. We recommend that you update the firmware to ensure that the charger works properly.

Maximum charging current
The setting of the maximum charging current must comply with the system dimensioning.

If the electric system dimensioning on the installation site requires a lower charging current than the charger’s nominal value, you can change the setting in this menu.

Connected phases
Select the phase the charger is connected to.

Phase rotation (only 3-phase chargers)
Selection of phase rotation is only informative and does not affect the charger operation.

Eathing System
The default setting for power supply is TN network. If you connect the charger to an IT network, you have to change settings for the charger accordingly.

Overcurrent limit

• Certain car models tend to take more charging current than set as the charger’s maximum charging current.
• In case an overcurrent of 10% lasts longer than 3 minutes, it results an error state. If the overcurrent is 16% it results an error state immediately.
• You can prevent unnecessary error states by setting an overcurrent limit.
• If the charging current is lower than 10A, you can set the overcurrent limit up to 30%.
