1P7K Installation Guide

Modified on Mon, 30 Oct 2023 at 03:47 PM

This guide will help you with the installation of your 1P7K charger. Installation of the 1P7K charger must always be performed by qualified personnel in electrical installations and in accordance with local electrical regulations.


Before starting to install and operate the 1P7K charger, you must read the user manual. Take into consideration all the warnings and follow all the instructions as described in the manual.

1. Unboxing 

You should find the following items in your 1P7K box. If you ordered the EM (Energy Management) package, you will also find it inside the box. After completing the installation of the 1P7K continue with the installation of the EM module.

2. Planning and Preparation

2.1 Tools

To properly install the 1P7K charger, the following tools are required: 

2.2 Planning

Before starting the installation, the following recommendations must be taken into consideration: 

  • Make sure the charger can be installed vertically, on a sturdy and fire-resistant wall, or on the optional metal pillar that can be purchased separately
  • Make sure there is enough space to install the charger
  • Make sure that the IP54 protection class of the charger can be maintained (protected against dust and water splashes).
  • Make sure that the necessary power supply cable (not included) from the junction box to the charger can be installed in accordance with the electrical regulations applicable in your country
  • Make sure that the electric vehicle can be parked for a long period in the vicinity of the charger in such a way that the included charging connector with its 5m of cable can be plugged into the electric vehicle’s charging port
  • If an optional metal pillar is used, make sure that this is mounted in the highest point of the floor, in such a way that during rain the metal pillar base will not be sitting in a puddle of water.  
  • Check local electrical regulations regarding the necessity of installing an external emergency switch for the 1P7K charger.

2.3 Site Preparation

Before installing the 1P7K charger, the electrical installation for the power supply of the charger must be put in place. The electrical installation for the power supply of the charger must have the next characteristics: 

  • Single-phase (230V | 50Hz) 3-wire (L, N, PE) flexible, flame-retardant, and self-extinguishing cable with a wire cross-section of 6mm2 or 10mm2;
  •  Appropriate electrical protection in the junction box. The electrical protection of the 1P7K charger must contain a residual current device (RCD) with a tripping current I∆n=30mA, type A, nominal current In>40A, and a manual reset, combined with a dedicated MCB (Miniature Circuit Breaker) with a nominal current In=40A, tripping curve B or C and a rated breaking capacity of 6kA. 
If your electrical installation does not support 7.4 kW, you can limit the charger to the maximum power your installation can handle. In that case, the power cable and protection can be selected according to the chosen power limit

3. Charger installation

After making sure that you have everything you need, and you chose an appropriate location for the charger, we can proceed with the installation of your 1P7K.

1. Mark the position of the charger’s 3 mounting points. For a quick and correct marking of the mounting points please use the included A3 quick installation guide, which also serves as a drilling template. You can tape it to the wall for easier installation. It is recommended to install the 1P7K charger at 1,3m above the floor. 


2. Drill holes in the wall where the mounting points are marked. The diameter of the holes depends on what type of screw anchors are used. Always use anchor screws dedicated to your wall surface (e.g. brick/concrete, drywall, insulation, etc. ) and follow the recommendations of the anchor screw manufacturer. Insert the screw anchor into the holes and make sure they are inserted all the way. If necessary, use a hammer and gently tap the anchor screws all the way into the holes. 

3.  There are 2 available easy-to-cut areas through which the power supply cable can be inserted into the charger. One area is on the rear of the enclosure and one area is on the bottom left side. These easy-to-cut areas are used to insert the power supply cable into the main body of the charger.  Using a step drill bit, drill out a 30mm diameter hole in one of these areas, depending on where you would like to cable to enter the charger.

If the rear cut-out area is used, insert the provided sealing cap in the cut-out hole. Insert the power supply cable through the sealing cap, to ensure water tightness. If the bottom left cut-out hole is used skip this step. 

4. Fix the main body of the charger on the wall by inserting the screws with the provided rubber sealing washer through the mounting points and tighten them with a screwdriver by hand. 

Take care when thightening the screws. Overtightening may damage the seals or cause the plastic
 enclosure of the charger to break.

5. If the power supply cable will enter the charger from below, install the cable gland in the drilled-out bottom left cut-out. Fix the cable gland into position by tightening the lock nut. Insert the power cable through the gland.

6. Strip the main insulation of the power supply cable and strip 12mm of insulation for each of the 3-wires of the power supply cable. 

7. Open the levers of the connectors that are mounted under the electronic circuit board, on the left side. Insert the 3-wires of the power supply cable into the WAGOTM connectors mounted on PCB and close each lever of the connectors. 

Be sure that the wires are fully inserted into the connectors, without bent strands and that no stripped parts of the wires or strands are visible.

Always follow the wires succession as labelled on the PCB (printed circuit board).
An improper wire succession may lead to an electric shock, damage to the charger or fire.

8. Check that the rubber seal mounted on the inside border of the enclosure is fitted tight in the designated place. (Fig. 9) If the front cover is installed over a rubber seal that is fitted improperly the IP54 protection class of the charger may be affected. 

9. Install the front cover by gently pushing it into place, first in the bottom 2 fixing hooks and then in the 2 top fixing hooks. 

10. Secure the front cover by screwing the two included screws into the bottom of the lid. A Philips screwdriver is needed with a PH1 head. 

11. Power up the 1P7K charger by arming the dedicated circuit breaker. The charger's LED cross should light up green.

Inside the cardboard box, you will also find a spare label, containing the serial number of the charger. Please keep this label somewhere safe, as the serial number will be required further and for any support request. 

For example, you can stick the label on the inside of your fuse board's door!

Congratulations! You have successfully installed your 1P7K charger! 

Continue with the configuration of your 1P7K charger using the dedicated app.
