2 General Safety LEAB Automotive GmbH
Notice
Reverse polarity can damage the equipment
Errors when connecting the cables can cause equipment damage.
1. 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.
1. 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 230V (+/- 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 elec-
tronic system prevents contact erosion. The operating display provides in-
formation about the current system status.

5 Creating a Body Cutout
NOTE
To ensure perfect operation, observe the following notes on the
assembly site:
1. Choose a vertical surface.
2. Choose a site with minimum dust and which is protected from
jet water.
3. 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.
ðThe body cutout is now created.
6 Installation
Preparation
Before connecting the unit, perform the following steps:
CAUTION!Install a suitable fuse in the vehicle (up to 16A).
1 Route a connection cable (H07RN-F, 3 x 2.5) in the vehicle.
2 Attach the connection cable to the vehicle installation.

6 Installation LEAB Automotive GmbH
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 sim-
ilar).
ðThe 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 cor-
responding screw terminals.
ðThe device is connected.
Optional: Connecting the Immobiliser
NOTE
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 1A).
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: 1A).
ðThe immobiliser is connected.

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:1Nm).
6 Attach the cover.
ðThe 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).
NOTE
Electronics to prevent contact burnout requires voltage
Contact N is electronically switched and is only open when a 230 V
voltage is applied.
