1) In case an "Ex d" rated 4-wire level gauge version is used, the power supply can be obtained from these terminals (21V ±10%).
2) The internal voltage at this terminal is 0 V, however, shielding and signal common should be connected to terminal 11 or 12.
3) option, s. pos. 20 of the product structure
