This chapter gives instructions how to install 1/8 DIN panel meter 2012. The field meter 2800-2012, large panel meter 910/920E-2012 and the large field displays xxxF-2012 have chapters of their own. Opening the enclosure The enclosure has to be opened only, if the jumper positions are changed or a card is added or removed. - Page 5 Supply voltage The power supply is connected in a three-pole connector, that has terminals numbered 7, 8, and 9. The supply is brought to terminals 7 and 9. The polarity does not matter. The 24VDC model has green connector block, while the 230VAC model has a grey one.
