Safety Instructions During Operation

Safety Instructions During Operation

 N/A
  • The power unit must only be used for its intended purpose
  • Do not exceed maximum permitted operating pressure
  • Ensure adequate ventilation for heat dissipation
  • Do not mount power unit onto moving parts
  • Power units and add-on equipment can get hot during operation - risk of injury
  • Refer also to HYDAC Operating Instructions and drawing no. 3111722

Requirements at The Installation Site

Requirements at The Installation Site

 N/A
  • Permitted ambient temperature range -20 ºC to +40 ºC
  • Do not mount power unit onto moving parts
  • Finish required on mounting surface 0.3 mm over 100 mm length
  • To avoid excessive noise, use flexible mounts and avoid mounting on resonating surfaces
  • To prevent vibration transfer, hoses must be used wherever possible when connecting the power unit
