Storage & Operating Environment (General)
· Extreme operating temperature: -40~70℃ (extremely low temperatures significantly increase joint friction; extremely high temperatures may trigger over-temperature alarm protection and shutdown)
· Normal operating temperature: -10~45℃; storage temperature: -30~60℃
· Operating & storage humidity: 20~80%RH (no condensation)
· Vibration resistance: 24.5 m/s² (frequency 10~400Hz)
· Environmental requirements: free from dust, metal powder, corrosive gases, flammable gases, oil mist, etc.; indoor use, avoid direct sunlight; air pressure: 86KPa~106KPa
Notes
· The no-brake model is printed as "CRA-RI00-142-PRO-2-XX" in the original manual (likely a missing "1"; should be RI100-142)
