## Safety

- Permitted installation height is not more than 1,000 m above sea level; use at higher altitude affects the permitted temperature.

## Study notes

- The document's long-arm table lists SRA120EL-01, SRA133L-01 and SRA168L-01; this record uses the SRA120EL-01 column.
- SRA series robots use Nachi FD controllers, which are not present in the reference controller list.
- SRA120EL-01 allowable static load torque is 687 N·m on axes 4 and 5 and 353 N·m on axis 6.
- SRA120EL-01 allowable moment of inertia is 60 kg·m² on axes 4 and 5 and 30 kg·m² on axis 6.
- The table lists a forem "1" load of 45 kg (90 kg at maximum).
- Sound level is stated as 79.6 dB(A) under JB-Z 873-1 (ISO 11201) at maximum payload and speed.
- Applications listed are machine tending, material handling, palletizing, spot welding and dispensing.
