Safety instructions
To protect you from electrical shocks, injury or burns
the following basic safety principles must be observed
when using electrical devices. Please read and follow these in-
structions before using the device.
Installation
Ensure that the devices are positioned safely and cannot fall
down or over. Always position the cables to ensure they do
not pose a tripping hazard. Do not expose electrical devices to
rain. Do not operate electrical devices in damp or wet environ-
ments. Do not operate electrical devices close to flammable
liquids or gases.
Protection against an electrical shock
Only operate devices whose casings and cables are undam-
aged. Ensure the cables are installed safely. Do not pull on the
cables.
Only operate the device if it has been secured with a
30 mA fault-current circuit breaker. The valid local in-
stallation regulations must be observed.
Use
During use, please observe the regulations of EN 60335-1: 2010,
according to which this device has not been designed for use
by people (including children) who have restricted physical,
sensory or metal abilities or a lack of experience and/or knowl-
edge, unless they are supervised by a person responsible for
their safety or have received instructions from that person as
to how the device is to be used.
Children should be supervised to ensure they do not play with
the device.
Do not use electrical devices for purposes other than those
stated by the manufacturer. The ventilation slits in the housing
must be free and may not be covered by luggage, towels or
clothing etc.
Before connecting or disconnecting cables, ensure that the
power supply has been interrupted! To do this, remove the
mains plug or the coupling plug to the towing vehicle and dis-
connect the battery.
Mains supply mode on ferries
The main supply voltage on ferries can be prone to heavy fluc-
tuations. Therefore, do not connect this device with this volt-
age without adequate protection.
Generator mode
Please observe the handling instructions in the manufacturer's
operating instructions. The generator must satisfy the 230 V
mains power connection values. The generator must comply
with the 230 V mains connection values. Only operate the
device on a generator that runs steady. The voltage peaks that
occur during the start-up and shut-down phase (e.g. due to a
lack of fuel) can damage the device.
Repairs
Do not repair or modify the device. Please contact your dealer
or the Truma Service (see service manual or www.truma.com).

Only use accessories and additional devices that are supplied
or recommended by the manufacturer.
Operating instructions
Application purpose
The device APS 450-HF generates from a 230 V AC voltage a
stabilised 12 V DC voltage to operate the consumers such as
e.g. water pumps, ventilators, bulbs. The device is designed
for installation into caravans.
Improper use
The device is not a charger and may not be used to
charge batteries.
Description
The device supplies a filtered and stabilised 12 V DC voltage
for the entire power output. All 12 V outputs are secured with
plug-in fuses.

Commissioning
The device is operational as soon as it is connected to the
mains supply.
Fuse change
The fuses are located below the clamping space cover that
needs to be removed before the fuse is changed (see "Re-
moval of clamping space cover"). Faulty fuses may only be
replaced with fuses of the same type after the fault has been
rectified. Replace the cover after exchanging the fuse.
Removing the clamping space cover
Unlock the clamping space cover by pressing the two straps
at the same time and then remove (see Page 2, fig. A).
To attach the cover, Push both straps into the slits of the cas-
