1.6.  controllers regular service conditons: The altitude above sealevel does not surpass 2,500 meters; The surrounding air temperature highest is +40 ℃, most is low is -25 ℃; The air relative humidity is not bigger than 90%; Does not have the  remarkable undulation and the impact vibration place; In does not have the explosion hazard in the medium, also in the medium does not have the sufficiently dipping and the destruction insulation gas and the dust (including electric
conduction dust); Is not having the sleet attack the place.  1.7 models significances:

1. machinery
   

   2.1 controllers outer coverings are the protected types.
   2.2 controllers contact systems for the double break point, the translation type, the extinguishing of arc system use the semi-enclosed type longitudinal seal pottery clay explosion chamber, and matches by the strong magnetism blows the electric circuit, extinguishing of arc ability.
   2.3 contacts systems structure for the building block box type, the two-row arrangement, the assembly is convenient, the structure compact disassembles and assembles easily.
   2.4 contacts closed and the separation relies on the bakelite cam piece composition different angle, with revolves the way realization.

5. build in and servicing
   

    6.1 installments precheck controller, like determination controller operation clever, when the files position is clear, the controller only then may install.
   6.2 controllers must reliably fix on angle iron stand 'or' operation. Taiwan, outside meet the electric cable wire to be possible to penetrate by the foundation on hole.
   6.3 controllers should reliably earth.
   6.4 controllers stators electric circuit contact must install the complete extinguishing of arc cover.
   6.5 with skids the friction in controller all rotations place, must the regular apply oil fat, by reduce the friction                                                                                                                                                         6.6 controllers when work the contact but produces as a result of the electric arc burns black or the singeing phenomenon, this does not affect its performance, does not need to eliminate, otherwise counter-
   can urge the controller to damage ahead of time.
   6.7 controllers contacts exceeds the quota the travelling schedule to be smaller than when 0.5 millimeter should exchange the new contact, when installs the contact system and moves, the static contact
   guidance place on its roller axis spreads the lubricating grease, and adjusts the double break point contact closed and the separation synchronism.
   6.8 should eliminate in the controller regularly the dust.
   6.9 pays attention to the fastening parts frequently whether has the loose situation, like has must eliminate.

6. Ordering notice (when ordering must indicate)
