Installation Instruction VARIODYN
Connection Main-Switch-Unit (MSU)  DOM and PA
1. Connect 230 V AC rated voltage / emergency power supply to the terminal block  of the MSU.
The protective earthing conductor (PE) and neutral conductor (N) must always be connected.
2. Connect the prefabricated power cord to the terminal block  of the MSU and to the IEC power socket  on
the rear side of the DOM.
3. To connect a power amplifier (PA) to the MSU, another prefabricated power cord must be connected to terminal
block  of the MSU for each amplifier and to the IEC power socket of the respective amplifier.
4. Use a CAT5 patch cable (yellow) to connect the ETHERNET connection of the MSU and of the DOM.
5. If a second amplifier (PA) is present, it must be connected to the free terminal block  of the MSU and to the
IEC power socket of the respective amplifier with another prefabricated power cord.
Ensure that the same load is applied to all phases when connecting. If it is not possible to guarantee
this, precautionary measures must be taken against a break in the neutral conductor occurring (e.g.
different loads through different connections).
