How do I install an Ohme Home Pro?

The Ohme Home Pro is designed to be wall mounted to a flat surface. Fixings are included which are suitable for most wall surfaces (e.g. brick/render) but the installer should select their own fixings if these are not appropriate.

Attach the back plate to the wall using the four fixings supplied.

Mount the unit, carefully guiding the three lugs into the rear of the unit.

Use the supplied three M4 short machine screws to fix the unit to the back plate.

The Ohme Home Pro is supplied with a one metre fixed input cable/flying lead requiring termination on-site to a suitable junction box, isolation switch, or mini-CU (not supplied). The flying lead conductors are 6mm2 copper, the overall diameter is 15.2mm, suitable for a No. 6 cable cleat.

To connect, typically an installer will either:

·  Install a junction box at ankle height
·  Feed the input cable through a wall and terminate on the other side

Note: The junction box needs to be rated to at least 32A, have sufficient IP rating for the location, and have space for a three-way terminal block (no load balancing) or five-way terminal block (with load balancing).

The Ohme Home Pro has a dynamic load-balancing feature. A current sensor (CT) clamp is provided to measure the electrical demand of the property, or sub-board. The unit will limit the maximum current available to the vehicle to keep the household demand below the set threshold/fuse value.

Where load balancing is activated, if the CT clamp is removed, installed in the wrong location or is faulty, the unit will revert to charge at a maximum of 16A. It is therefore sensible to ensure the spare capacity, after taking account of other loads and diversity, is at least 16A.

The charger comes complete with a cable holder and charging gun holster to retain the cable and vehicle connector when not connected to the vehicle. Use a further four fixings to mount these to the wall.

Once the charger is installed and connected to power it will turn on and be ready for commissioning.

When the charger is unplugged from the vehicle it must be stowed away correctly.

Wrap the cable around the cable holder.

The charger plug must be pushed into the holster, you will hear a click when it is locked in place. This protects the charging pins from the elements. Push the button on the top of the holster to release the charging plug.
