## Safety

- Requires a shield room if discharge noise can interfere with surrounding radio, television and other sets.
- Install under oil mist free and dust free environment with humidity 75% RH or less.
- Ground resistance should be less than 10Ω and isolated from other machines.
- Maximum vibration amplitude should be 2 nm or less under frequency band 10 to 20 Hz.
- Air supply: 0.5–0.7 MPa, flow rate 160 L/min or more.
- The machine has a safety cover; floor plan dimensions in parentheses are when the safety cover is open.

## Study notes
