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.

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.

About this Product

The MelfBox is a vehicle electrical supply system. It has a potential-free switching contact (normally open contact) to create an immobilizer. An electronic system prevents contact erosion. The operating display provides information about the current system status.

Creating a Body Cutout

NOTE
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.

To create the body cutout, proceed as follows:

Saw a hole (Ø 55 mm) in the vehicle body.
To prevent corrosion, seal the cut surfaces.
⇒ The body cutout is now created.

Installation

Preparation
Before connecting the unit, perform the following steps:
CAUTION! Install a suitable fuse in the vehicle (up to 16 A).

Route a connection cable (H07RN-F, 3 x 2.5) in the vehicle.
Attach the connection cable to the vehicle installation.
Optional: Route a cable (H05RN-F, 2 x 0.5) for the immobilizer 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 Unito connect the device, proceed as follows:
Pierce the housing seal at the intended location with a pointed tool.
Feed the connection cable (H07RN-F, 3 x 2.5) through the hole.
Connect the wires of the connection cable to the corresponding screw terminals.
⇒The device is connected.
Optional: Connecting the Immobiliser NOTE
The MelfBox has a potential-free switching contact (normally open contact) to create an immobilizer.
The design of the immobilizer depends on the vehicle. Inquire from your vehicle manufacturer.To connect the immobilizer, proceed as follows:
CAUTION! Install a suitable fuse in the vehicle (up to 1 A).
Insert the immobilizer cable (H05RN-F, 2 x 0.5) through the second hole of the housing seal.
Insert the wires of the immobilizer cable into the pushin terminals (max. current: 1 A).
⇒The immobilizer is connected.

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.

Place the housing seal in the cap.
Attach the cap to the supply unit with the 3 screws (3.5 x 14).
Check the tightness of the housing seal.
Push the supply unit into the body cutout.
Tighten the 3 screws on the front until the supply unit is firmly seated in the body cutout (maximum torque: 1 Nm).
Attach the cover.
⇒The device is mounted and ready.

Operation

Notice
Inactive immobilizers can cause damage
Note that the immobilizer only works when the MelfBox is active (operating display illuminated).
NOTE
Electronics to prevent contact burnout require voltage Contact N is electronically switched and is only open when a 230 V voltage is applied.

To install the device, proceed as follows:

Plug the two-pin earthed plug of the connection cable into a 230-V mains
supply.
Open the flap of the supply unit.
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.

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”.

Cleaning and Maintenance
