AA87.B and TC RU C-DE. ГБ05.B EAC Ex In conjunction with a CYK10-G**1 measuring cable or a Memosens measuring cable that is structurally identical and features the same hardware and method of operation, the listed sensors may be connected to the certified, intrinsically safe sensor inputs of the Liquiline M CM42-MG, Liquiline M CM42-NG and Mycom S CPM153-G or MemoLink devices. Alternatively all of the listed sensors can be connected with a measuring cable to a certified, intrinsically safe output circuit with the maximum values specified below. In particular the maximum internal inductance and capacity of the intrinsically safe output circuit must not exceed the specified maximum values; see the "Connection values" 5 table. The electrical connection must be carried out according to the wiring diagram of the transmitter used. ISFET sensors CPS441D, CPS471D and CPS491D must not be operated under process conditions where electrostatic charging of the sensor and connection system can be expected. Intended use of the sensor in liquids with a conductivity of at least 10 ns/cm can be classified as electrostatically safe. ph-/orp glass sensors CPS11D, CPS12D, CPS16D, CPS41D, CPS42D, CPS71D, CPS72D, CPS76D, CPS91D, CPS92D and CPS96D must not be operated under process conditions that are at risk of electrostatic charges. Avoid strong steam or dust currents that act directly on the connection system. When installed in Zone 0, Memosens measuring cable CYK10-G/I and its connectors must be protected against electrostatic charges. Ex versions of digital sensors with Memosens technology are indicated by an orange-red ring. The maximum permitted cable length is 100 m. The stipulations for electrical connections in hazardous areas (e.g. EN/IEC ) for the use of sensors and measuring devices must be observed. 4 Endress+Hauser
