1 STT 3000 Series STT250 /150 Surge Protection Device Specifications Part Number: EN2I-6061 June 2011 Introduction This device is designed to give the Smart Temperature Transmitter maximum protection against surges such as those generated by lightning strikes. It mounts right on the top of the STT250 or STT150 terminal block, providing easy field wiring and also protection for the integral meter if used. The compact mounting allows the use of a variety of housings including the popular Honeywell explosion proof field mount housing (Table II selection E - - ). The device can be used in both intrinsic safety and flame/explosion proof applications, refer to the STT250/ STT150 safety certificates for the detailed specifications. Specifications The surge protection is based on a gas-filled discharge tube and solid state electronics. It does not affect the transmitter wiring, since less than 1 Ohm is added to the loop resistance. The protection is designed to limit the voltage that can occur between lines and between lines and earth, therefore the unit will not pass a di-electrical strength test.

3 STT 3000 Smart Temperature Transmitter 3 Installation If an indicating meter is used, remove the shunt on the surge protection. In all other cases, the shunt must be present. Remove the cover/cap of the housing (if applicable). The device fits on the top of the transmitter module terminal block and the transmitter output screws (+ and -) fix mechanically the device. Attach the grounding wire to the ground screw in the housing. Connect a wire from the transmitter enclosure to local earth ground. Use size 14 AWG or 2.0mm2 bare or green covered wire. If an indicating meter is used, wire according the drawings beside. Connect the 4 20mA loop to the + and terminal screws of the surge protection and close the cap of the housing. Maintenance The unit is designed to give a long normal service life. However, if exposed to a large number of high energy transients beyond the capability of the unit, it may fail. The unit has been designed so that, under excessive surge conditions (more than 10 KA), it should fail, protecting the transmitter. If the unit has failed, it can be replaced in the field the process for removal in the reserve of that for installing the unit. If a replacement is not immediately available, it is possible to bypass the unit by wiring directly to the transmitter; however, it should be remembered that, in this case, the transmitter will be unprotected from surges.
