1. Safety
*1: The exhaust system in the Cleanroom-model Manipulator (G10/G20-***C*) draws air from
the base interior and arm cover interior.
A crack or other opening in the base unit can cause loss of negative air pressure in the outer
part of the arm, which can cause increased dust emission.
Do not remove the maintenance cover on the front of the base.
Seal the exhaust port and the exhaust tube with vinyl tape so that the joint is airtight.
If the exhaust flow is not sufficient, dust particle emission may exceed the specified
maximum level.
Cleanliness level: Class ISO 3 (ISO14644-1)
Exhaust System: Exhaust port diameter: Inner diameter: ø12 mm/Outer diameter: ø16 mm
ESD specification uses resin materials with antistatic treatment. This model controls
adhesion of dust due to electrification.
*2: IP (International Protection) for the Protected-model Manipulator indicates International
Standard of the protection level against dust and water.
