Installation instructions

Safety instructions
This device contains parts that could cause sparks or
a light arc!
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 specified cable cross-sections and fuses of the
correct strength!
The installation of the device must comply with the techni-
cal and administrative provisions of the respective country
in which it is used (e.g. EN 1648). National regulations and
guidelines must be observed.
Assembly
(See page 2, fig. B).
Before commissioning, the APC 310 must be wired to the
APS 400-K.
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 80 °C.
Ensure that the ventilation slits remain free! Inadequate
ventilation can cause the device to overheat!
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.
If the temperature inside the device increases 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.
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.
Secure the device with four screws (diameter 5 – 6 mm – not
countersunk head screws). The screw length and torque de-
pend on the underlying surface.
Handling the cage tension spring clamps
Prepare the connection cables. Remove 8 – 9 mm of the in-
sulation sheath on the end of the cables for the small cage
tension spring clamps. The cable ends for the battery con-
nections (large cage tension spring clamps) must be stripped
12 – 13 mm. Cable end sleeves are not required.
The spring terminal can be opened up with the aid of a suit-
able slit screwdriver.
Insert the tip of the screwdriver into the upper, square open-
ing, and push on the spring terminal. The spring terminal in
the lower, round opening opens up.
Insert the cable into the spring terminal as far as the insula-
tion (lower, round opening) and remove the screwdriver. The
tension spring clamp closes again and the cable is securely
clamped.
Repeat the process for all connections to the terminals X1a/b,
X5, X6 and X11a/b.
Make sure that the cable ends sit firmly in the cage tension
spring clamps!
Connection
Before connecting or disconnecting from the cables,
ensure that the power supply is completely interrupted!
To do this, disconnect the mains or couplig plug from the tow-
ing vehicle and disconnect the battery.
Cable lengths and cross-sections
Model complies with EN 1648-1 und VDE 0100, Part 721.
The cable connection between the APS 400-K and the
APC 310 must not exceed 0.45 m in length.
Energy source / consumer connection
Connect the device to the energy source (e.g. battery, dyna-
mo, charger) and the consumers (e.g. refrigerator) as shown
in the wiring diagram. Check that the terminals are connected
correctly.
Always position the fuses close to the energy source
(e.g. battery, dynamo, charger). Only use the specified
cable cross-sections and fuses of the correct strength!
Panel
There is a suitable panel available for the device. Please ask
your dealer. There is a master switch integrated into the panel.
Once the panel is connected, any separate master switches
will become obsolete.
Truma Temperature Sensor
If you use a temperature sensor for battery II, stick the tem-
perature sensor to the face side of the Battery II (supply bat-
tery). To do this, remove the protective film from the adhesion
point on the temperature sensor and press firmly at the re-
quired position on the Battery II (see description temperature
sensor). Connect the cable of the temperature sensor to the
temperature sensor connection of the device.
For temperature-controlled battery charging, we recom-
mend using a Truma temperature sensor, especially with
AGM batteries. Please ask your dealer.
Battery type change-over switch
Set the battery type (AGM, gel, liquid = liquid electrolyte) of
your battery II on the battery switchover.
Connection master switch
When using the APC 310 with expansion via a panel, the plug
for the separate master switch is connected to the 2-pin con-
nection of the module APC 310.
Cable fixing
Secure all cables (e.g. to energy sources, consumers and ac-
cessories) with cable ties (see page 3, fig. D).
Final tasks
– Check all connections are tight.
– Connect the batteries.
– Create the connection with the 230 V AC mains supply via
the female device plug on the APS 400-K.
– Attach the clamping space cover(s).
