1.0 General

1.1 Description of product and application

Dometic AC/DC converters are used for the power supply of 12 V appliances in continuous operation. The input voltage thereby comes either from the 230 V AC mains power supply (Priority 230VAC).

2.0 Safety instructions

2.1 Application according to regulations

Dometic AC/DC converters are used for the power supply of 12 V appliances in continuous operation.

2.2 User's responsibility

Anyone operating the Dometic AC/DC converters must be familiar with the safe handling and understand the instructions in this operating manual.

Non-observance of the following safety instructions can result in serious damage to the Dometic AC/DC converter and adjacent areas.

WARNING!

Do not make any changes to or additional installations at the Dometic AC/DC converter or to the installation performed by the vehicle manufacturer.

WARNING!

The Dometic AC/DC converter must not be used in potentially explosive gas or dust areas.

CAUTION!

The Dometic AC/DC converter must not be covered or exposed to environmental conditions which adversely affect the ventilation of the unit.

3.0 Operation of the AC/DC converter

3.1 Switching on

■ Devices of the type 1 (see Fig. 4page 33) can be switched on and off using the On/Off switch. 230 V AC input voltage is available when the LED under the ON/OFF switch is lit green. If the green LED does not light, there is no 230 V AC input voltage present at the unit or the device has switched off due to overheating (see point 3.2.1).
■ Devices of the types 2 a + b switch on as soon as 230 V voltage is available at the connection.
The consumers can be supplied with power independently of the 230 V operation using a 12 V DC energy source (e.g. battery) if this is connected to the converter. The internal priority circuit disconnects the 12 V DC energy source automatically as soon as 230 V AC is present. The AC/DC converter is not a charger.

Note that high currents flow over the units due to the device-specific high power although they only produce a voltage of 12 V. Strictly ensure that the power of the consumers connected to the respective output complies with the requirements under point 3.2.4. Changes to the installation must only be performed by authorised specialists in agreement with the vehicle manufacturer.

3.2 Safety devices

Dometic AC/DC converters have various safety functions for your safety.

3.2.1 Overtemperature protection

■The thermal overload cut-out trips in the case of the unit overheating. To reactivate the unit, first switch it OFF. Wait for at least 60 seconds before restarting the system. 230VAC supply
As soon as the circuit breaker (in the fuse box) is in the ON position and the vehicle is connected to a 230V AC power supply, the AC/DC converter is ready for operation. 12VDC supply
If no 230V AC supply is available, a 12V DC power source (e.g. battery) can be connected to the AC/DC converter; the consumers will then be supplied from this source.
If the thermal overload cut-out trips again and switches off the appliance, the cause may be insufficient ventilation. If this is the case, provide better ventilation and restart the unit.
If the thermal overload cut-out still trips afterwards, please contact an authorised Dometic service partner.

3.2.2 Overload protection and short-circuit protection

The overload cut-out trips under the following conditions:

In the case of moderate overload which results in high internal temperatures with increasing operation duration and then trips the overload cut-out mentioned above. This reduces the output voltage and the under voltage cut-out trips.

The unit is equipped with internal short-circuit monitoring. As soon as a preset value is reached, this cut-out trips and switches off the unit without blowing fuses. Caution is required in this case.

3.2.3 Surge voltage protection

The Dometic surge voltage protection (OVP unit, Fig. 1) is installed upstream of the transformer. It disconnects the supply line if the input voltage exceeds approx. 270 V\~. Connected equipment is protected.

A red LED (1) indicates that a surge voltage was present.

The Dometic surge voltage protection resets itself automatically when the voltage has reached a normal level again. The LED is still lit 20 to 30 minutes after the voltage has reached a safe level again.

Fig. 1

3.2.4 Fuses

The power units can be fitted with different fuses.

It must be strictly ensured during the installation that the power taken off at the individual fuses is maximum 75% of the rated value of the respective fuse. Higher outputs can result in overheating and damage due to the higher current.

A defective fuse usually means a short-circuit or an overload of the 12 V output. This is indicated by a red LED lighting next to the fuse (see Fig. 2) if a consumer is connected.

A defective fuse in the fuse holder is also only indicated when a consumer is connected. In the case of a defective fuse, attempt to localise the cause in the 12 V power circuit and rectify if possible.

Switch off the AC/DC converter or disconnect the device from the 230 V AC power supply

before replacing the fuse. Only replace a defective fuse with a new fuse of the ATO type LITTLEFUSE.

Switch on the unit again (see Fig. 4). If the fuse trips again, contact a service partner for Dometic AC/DC converters.

3.3 Measures in case of mal- functions

1 No current supply to 230 V and 12 V mains operation; the green LED does not light up.

a. Check whether power has been disconnected; restore connection, if necessary. Check whether the automatic cut-out has been activated.

2 No current supply to the 12 V mains operation.

a. Check the 12 volt plug-in fuses: faulty fuses are indicated by the red LED.

If necessary, replace the fuses by new fuses of the same type and the same current intensity.

b. Check whether the unit has switched off because of overheating: the green LED does not light up. Switch off the unit and wait at least 2 minutes before restarting it.

3 No current supply to the 12 V outputs by battery operation.

a. Check the 12 volt plug-in fuses: faulty fuses are indicated by the red LED. If necessary, replace the fuses by new fuses of the same type and the same current intensity.

b. Check the battery and its connection to the converter.

4.0 Installation

4.1 Installation

WARNING!

Dometic AC/DC converters are permanently installed and connected by the vehicle manufacturer. It is not permitted to connect cables to the unit or remove them from it or to modify the installation in any other way.

■ Install the AC/DC converter at a place which is well ventilated and protected against moisture. In order to achieve optimum heat removal, the device must be mounted vertically (see Fig. 2).
■Comply with the stated clearances for the installation. There must be no easily inflammable materials such as textiles, paper etc. located in this area.
■ Ensure that the air circulation is neither obstructed by covers or other disruptive influences.
The AC/DC converter can only be operated with sinusoidal mains voltage (230 V AC). If a generator provides this voltage, surge voltage protection should be installed upstream of the power unit.

4.1.1 Vertical Installation

The optimum installation of the AC/DC converter is in the vertical position (Fig. 2). The maximum permitted ambient temperature is 50 °C.

A: Wall
B: Side wall
C: Ceiling
D: Floor / platform
E: maintain a distance of at least 200 mm above the power unit
