2. Installation.
The safety transformer must be installed by a qualified installer, holding the relevant certificates, required and
necessary in the particular country for connecting (interfering with) the 230 V systems and low-voltage installations.
Because the transformer is designed for the continuous operation and is not equipped with ON/OFF switch, the
power supply line should have the appropriate overload protection. The user should be informed how to disconnect the
transformers from the mains (usually be means of the separate fuse in the fuse-box). The power supply installation
should conform to the applicable standards and law.
To maintain the required degree of protection class (IP43), transformer must be installed in a vertical position as
shown in Fig.1 / Fig.2.
The transformer should be installed indoors (controls cabinets, casings), where air humidity is
normal (RH=90% max. without condensation) and temperature in the range of -10°C to +40°C.
Provide sufficient airflow around the transformer for convectional cooling.
Caution!
Prior to entering installation it is necessary to make sure if the voltage
in the 230 V circuit is disconnected.
All service works inside the housing must be carried out with 230 V supply
voltage disconnected.
1. Install the transformer at the selected place: plain surface or on the DIN rail with the adaptors (AWO466 for
TRZ40VA ÷ TRZ60VA or AWO467 for TRZ50VA ÷ TRZ80VA) and evacuate connection wires.
2. Supply conductors ~230 V should be connected to 230 V L-N terminals of the transformer.
3. Connect the output transformer to a device, using installed cables
Remarks: Connect required voltage U1 or U2 or U3 (secondary voltage) for the correct device. The power of
connected devices must not exceed the power of the transformer.
4. If necessary, make other connections required for the correct type of system / device.
Remarks: consistent with requirements and recommendation of the producer.
5. Start the system (switch on ~230 V), adjust or configure: according to procedure of the producer’s system.
