Leveling the cabinet and testing the insulation

Leveling and fixing the cabinet.
1. Remove the four adjusting bolts attached on the bottom enclosure frame, install them on the adjusting nuts.
2. Check whether the cabinet is horizontal or vertical by using a spirit level and a plumb line respectively.
3. If the cabinet is not horizontal, adjust the adjusting bolts by using a socket wrench.
4. When the cabinet is horizontal, fasten the four expansion bolts to 45 N·m.

  The adjustment range of adjusting anchor is from 0 mm to 10 mm.
Testing the insulation of the cabinet.
1. Set the multimeter to read mega ohms.
2. Measure the resistance between the expansion bolt and the ground bolt of the rack, the measured resistance is more than five mega ohms.

  If the measured resistance is less than five mega ohms, check whether any insulation part is damaged or not installed. Measure the resistance again. Otherwise, remove all components, install and fasten the cabinet again.
