6.3 INSTALLATION OF THE PEM2 TOUCH SCREEN

where it will be free as possible from moisture, large fluctuations of temperature and particularly of
vibration shock. Also influences such as large magnetic fields caused by transformers, relays or
electromagnets must be avoided.
2. All cable connections should be made using cables as specified in section 6.4.
3. Connect the RS485 Modbus cable from the stator control box and 24VDC power supply to the
backside of the PEM2 touch screen in accordance with Figure 4 and Figure 5.
