    6F9G0154 5.INSTALLATION When installing , protect from dust. Particularly when the contactor is installed while the building is under construction , shield it from cement dust and other foreign matter. The following precautions should be taken. (1) The mounting surface must be horizontal (level : less than ±1mm). When the mounting surface is not horizontal , adjust with spacers.

    6F9G0154 9. OPERATION The drive unit for the electromagnet is installed in the bottom frame. Molded and wired on the printed circuit. The closing circuit can be operated using either in AC or DC by the drive unit. The optional latch trip circuit uses DC as standard. When a latched contactor is operated using AC power, it is recommended that a Capacitor trip device be used.

  • Page 14 6F9G0154 10.Trial operation Warning : Make sure main power is OFF. After mounting and wiring of the vacuum contactor, make the following inspections. 1) Check for any loose connections. 2) Check for any wiring errors. Perform this test with only the control circuit energized. confirm that the operation is correct.
  • Page 15 6F9G0154 11.INSPECTION AND MAINTENANCE To maintain the function and performance of the vacuum contactor for a long period of time, the following inspections and maintenance procedures are recommended. The intervals between inspections may vary depending on the conditions of use and the environment under which the contactor is used.
  • Page 16 6F9G0154 (2) Periodical Inspection/Detailed Inspection(every 1-2 years or every 20,000 operations) The facility should be removed out of service and perform inspection According to the instruction given in Table 6. WARNING : Contact with energized components can cause severe injury or death.

  • Page 20 6F9G0154 (2) Mechanical service life The normally energized type has the mechanical service life of 0.25 million operations , and the latch type 0.25 million operations. (The mechanical service life of the vacuum interrupter is 100,000 operations.) For the components listed below , replacement or detailed inspection and cleaning are recommended after the indicated number of operations.
  • Page 21 6F9G0154 (3) Service life of capacitor Opening and closing of the capacitor produces sever conditions for contactors, such as high frequency inrush current and interpole recovery voltage more than twice the normal voltage. The criteria of the maximum number of the capacitor current switching operations is shown in the graph below.
