The cable harness is not part of the Exprototype test certificate and must therefore be tested for safety-relevant functionality withinthe complete installation by the installer or operator.Consider the following issues:• Consider the local regulation concerning the setup of electrical devices within hazardousareas. This applies particularly to EN 60079-14 for the setup of the screen and thepotential compensation between the actuator, the electronic unit and the motor protectionunit (see 1) in chapter Cable shield, page 18 and chapter Terminal connectiondiagrams, page19 ff.• For the connection of the motor and the position transmitter only use ATEX certified EExe cable glands with IP 66 acc. to EN 50019.• Use a cable socket or a solid wire, bended to a "U", to connect the motor cable.• Ensure a proper strain relief for all cable connections.• Protect all cables in the connections chambers against contact with metal components.Ensure a gap of at least 6 mm between all conductive components.• Remove the desiccant in motor and position sensor.• Do not change the factory-set position of the motor terminal chamber.• Seal all not used cable entries with ATEX certified IP 66 plugs.• Use a certified cut-off unit for the thermal motor monitoring. Permitted units are, e.g.:- ABB motor temperature monitoring unit SD 241 B- 3 RN 1011-1 CK 00 , Ex II (2) GD , PTB 01 ATEX 3218, SiemensPos: 12.3 /======= Seitenumbruch ======== @ 0\mod_1126532365768_3101.doc @ 3830
