in accordance with the respective valid national installation
regulations.
Only qualified technicians may assemble and connect electri-
cal devices!
Ensure that the power supply has been disconnected! Discon-
nect the mains plug!
Only use the supplied parts and the specified cable cross-sec-
tions and fuses to connect the device!

Installation

Remove the equipment pack (accessories) and check it is
complete:
1 plug connector, 4-pole
1 fuse extraction pliers
1 plug connector, 6-pole
5 contact pins
1 plug connector, 12-pole
1 instructions for installation and use
2 mains supply cable, 1 m long, assembled
4 fastening screws with washers
The device should be installed away from damp and wet. The
installation site should be clean, dry and well ventilated. Dur-
ing operation, the casing can heat up to around 75 °C. There-
fore observe a minimum clearance of 100 mm and ensure that
the ventilation slits are not covered.
The designated room in which the device is to be installed
may not undercut the following dimensions as a minimum
clearance of 100 mm all-round must be observed.
Length: 475 mm / Width: 390 mm / Height: 215 mm
The installation space for the device must have ventilation
openings at the top and side that provide a total opening sur-
face of 100 cm².
Liquid electrolyte batteries need to be placed in a separate
box with ventilation directed to the outside. The gel and AGM
batteries do not need a separate box. Observe the installation
regulations of the battery manufacturer.
Securely attach the device using the 4 supplied mounting
screws.
Ensure that the ventilation slits remain free! There
should be a minimum clearance of 100 mm all round!
Inadequate ventilation can cause the device to overheat!
The device is designed for operation in an ambient tempera-
ture of up to 35 °C. If the temperature inside the device in-
creases due to a lack of circulating air or due to the fact that
the ambient temperature is too high, the charging current is
automatically reduced gradually.

Connection

Before connecting or disconnecting the cables, the
supply lines to the battery and mains supply must be
disconnected! Only use the specified cable cross-sections and
fuses of the correct strength!

Assembling the contact pins
Prepare the connecting cable. Please ensure that the contact
pins for the correct cable cross-section are pressed tightly
onto the cable ends and sit securely! Loose contacts may
lead to short circuiting and to poor connection. Cable ends
designed for use with cable end sleeves must not be soldered.
Remove a length of 5 mm of insulation from the connecting
cable.

Push the contact pin that fits the cross-section of the cable
over the connecting cable, so that the bared part sits in the
front clamp. The second clamp must enclose the insulated
part.

Now attach the connecting cable to the contact pin by
pressing the clamps together, using suitable crimping pli-
ers. Check that the connecting cable is firmly attached to the
contact pin.
