3. Checking interconnections
After temporary leveling is finished, check and confirm the following items before switching the
power on.
•
Grounding (class 3 grounding work) Class D (formerly class 3) grounding requirements
• Screws at terminals (must be tight)
• Connection of cannon connectors and other connectors

Relays (must be fitted and connected correctly)
4. Final level adjustment
After the second stage concrete has solidified, adjust the machine level using the leveling bolts.
Place precision levels on the upper surface of the table.
Precision level accuracy: 0.02 mm (0.00079 in.)/division
For details of the procedure to adjust the machine level and allowable leveling error, refer to our
