Can I install the levelling system myself, and what support is provided?
The electrical side can be done with the manual and phone support; mounting the jacks is structural work and needs the maker or a project engineer.
The kit comes with a wiring diagram and a user manual, and installation and commissioning support is also given over the phone. It is possible to do the electrical side yourself by following the manual; but mounting the jacks on the chassis is structural work, and for the mounting point and for reinforcement where needed you have to consult your caravan manufacturer or an authorised project engineer. Thinking of the installation as these two separate jobs also makes the decision easier.
1. Mechanical installation (structural)
Attaching the 4 jacks to the chassis. Each jack has a load capacity of 2000 kg and transfers this load to the chassis at a single point. Choosing the mounting point, drilling the holes and adding reinforcement where required call for a structural decision. At this stage, consult your caravan manufacturer or an authorised project engineer. A badly chosen mounting point gives no sign in the first days; because it puts the load onto a section of the chassis that is not suited to carrying it, the damage builds up over time and becomes permanent. The edge of every hole that is opened also becomes open to corrosion; on a galvanised or painted chassis, closing the mouth of the hole with a suitable protective coating prevents rust from starting in the first season.
2. Electrical work and commissioning
Connecting the GRV485 control unit to the battery and to the 4 jacks, and fixing the ASX103 to a rigid surface with its axes aligned. The wiring diagram and user manual in the kit describe these steps. The most frequent mistakes on this side are these: fixing the sensor to a surface that is not parallel to the chassis plane, choosing too small a supply cross section and causing a voltage drop, and putting the fuse far from the battery terminal. Do not skip the order either: do not connect the battery before the connections are complete, and read the positive and negative terminals once more before you first apply power. The cheapest way to rule out a reverse connection is to do the installation with the battery disconnected.
Who should do which job
| Job item | Can you do it yourself | Reason |
|---|---|---|
| Choosing the jack mounting point | No | A structural decision, the manufacturer's opinion is needed |
| Chassis reinforcement | No | A matter of welding and section calculation |
| Cable routing and fusing | Yes, following the diagram | The diagram in the kit describes the steps |
| Fixing the sensor and Tare | Yes, with care | A rigid surface and flat ground are required |
Where doing it yourself is not appropriate
If you cannot see the chassis section, if a water or gas line runs through the mounting area, or if the vehicle has a sandwich panel floor, do not decide the hole position yourself. If your vehicle is a type-approved series production unit, ask about the modification and inspection side of the added equipment from the outset. Do no work that requires welding while the vehicle battery is connected. Do not forget that the responsibility for an installation you carry out yourself is also yours; when a structural fault comes out later, it is hard to document.
Support and first commissioning
- Installation and commissioning support by phone.
- Remote parameter updates and software intervention.
- Automatic software updates via OTA.
- 2 year warranty.
At first commissioning, position the caravan on ground as flat as possible and perform Tare, then inspect each jack one by one in manual mode; the first commissioning steps are applied in order. During and after the test, do not lift all wheels off the ground, and use the handbrake and chocks. As you connect the cables, mark which jack goes to which channel; if a jack later runs in the wrong direction you will find the problem within minutes.
