Open and damaged cables can cause short circuits that can lead to serious
injuries.
- Before operating, make sure there are no open or damaged cables.
- Replace defective parts or damaged cables immediately.
Notice
Reverse polarity can damage the equipment
Errors when connecting the cables can cause equipment damage.
- Before operating, make sure that all cables are connected correctly.
Notice
Equipment damage and risk of cable fire
Using the unit at too high a voltage can lead to cable fire and equipment
damage.
- Only use the device within the specified voltage limits.
2.1 Intended Use
The MelfBox is a vehicle electrical supply system.
The system is designed to operate with a nominal voltage of 230 V (+/- 10%).
The IP55 rating protects it against the ingress of dust in damaging quantities
and against water jets.
2.2 Foreseeable Misuse
Only use the system within the specified voltage limits of 230 V (+/- 10%).
Do not point a high-pressure cleaner or other devices directly at the system
when cleaning the vehicle.
3 About this Product
The MelfBox is a vehicle electrical supply system. It has a potential-free switching contact (normally open contact) to create an immobiliser. An electronic system prevents contact erosion. The operating display provides information about the current system status.

5 Creating a Body Cutout
TIP
To ensure perfect operation, observe the following notes on the assembly
site:
- Choose a vertical surface.
- Choose a site with minimum dust and which is protected from jet water.
- Make sure that there is sufficient space at the assembly site.
Fig. 2: MelfBox dimensions
To create the body cutout, proceed as follows:
1. Saw a hole (Ø 55 mm) in the vehicle body.
2. To prevent corrosion, seal the cut surfaces.
The body cutout is now created.
6 Installation
Preparation
Before connecting the unit, proceed as follows:
CAUTION! Install a suitable fuse in the vehicle (up to 16 A).
1. Route a connection cable (H07RN-F, 3 x 2.5) in the vehicle.
2. Attach the connection cable to the vehicle installation.
3. Optional: Route a cable (H05RN-F, 2 x 0.5) for the immobiliser in the
vehicle and connect it to the specific vehicle installation (control module or
similar).
The unit is now ready to be connected.
Connecting the Supply Unit
To connect the device, proceed as follows:
4. Pierce the housing seal at the intended location with a pointed tool.
5. Feed the connection cable (H07RN-F, 3 x 2.5) through the hole.
6. Connect the wires of the connection cable to the corresponding screw
terminals.
The device is connected.
Optional: Connecting the Immobiliser
TIP
The MelfBox has a potential-free switching contact (normally open contact) to
create an immobiliser.
The design of the immobiliser depends on the vehicle. Inquire from your
vehicle manufacturer.
To connect the immobiliser, proceed as follows:
CAUTION! Install a suitable fuse in the vehicle (up to 1 A).
7. Insert the immobiliser cable (H05RN-F, 2 x 0.5) through the second hole of
the housing seal.
8. Insert the wires of the immobiliser cable into the push-in terminals (max.
current: 1 A).
The immobiliser is connected.
TIP
To protect the contacts of the immobiliser, their cable is connected to the
MelfBox via a Phoenix plug.
- Before disassembling the MelfBox, disconnect the Phoenix plug of the immobiliser cable above the connection terminals.
7 Assembly
To install the device, proceed as follows:
The cables in the MelfBox housing are correctly connected.
The body seal is firmly seated on the housing.
1. Place the housing seal in the cap.
2. Attach the cap to the supply unit with the 3 screws (3.5 x 14).
3. Check the tightness of the housing seal.
4. Push the supply unit into the body cutout.
5. Tighten the 3 screws on the front until the supply unit is firmly seated
in the body cutout (maximum torque: 1 Nm).
6. Attach the cover.
The device is mounted and ready.
8 Operation
Notice
Inactive immobilisers can cause damage
Note that immobiliser only works when the MelfBox is active (operating display
illuminated).
TIP
Electronics to prevent contact burnout requires voltage
Contact N is electronically switched and is only open when a 230 V voltage is
applied.
To install the device, proceed as follows:
1. Plug the two-pin earthed plug of the connection cable into a 230-V mains
supply.
2. Open the flap of the supply unit.
3. Plug the coupling into the supply unit.
The voltage input is provided at the load output of the supply unit. Connected
consumers are supplied. The operating display shows the operating status of
the device.
8.1 Operating Status
| LED | Operating status |
|---|---|
| Blue, flashing | The MelfBox is active. |
A minimum of 50 W power is removed from the supply unit (the greater the
power, the faster the flashing).
Yellow, steady light | The MelfBox is active.
No power is removed.
- Check the connection of the consumers.
- Check the fuse at the outlet of the MelfBox.
NOTE! This operating status only occurs immediately after inserting the
MelfBox coupling. The MelfBox does not switch back from “blue” to “yellow”.
9 Cleaning and Maintenance
