2 Installation and commissioning
2.9.1. Additional installation procedure
Continued
WARNING!
If the air pressure exceeds the specified, it could result in a brake failure in the motors and
cause the robot arms to fall down, leading to personal injury or physical damage.
NOTE!
To secure the supply of air pressure, it is recommended to use a pressure sensor.
Pressurize the motors, balancing device and serial measurement board cavity
The robots are prepared with hoses to the motors and the serial measurement board cavity to
enable pressurizing of them.
WARNING!
The robot must be pressurized also when it is switch off, to avoid that the humid
environmental air is sucked into the motors when cooling down.
Protecting robot from high pressure water
WARNING!
No part of the robot should be exposed to direct high pressure jet of water. The sealings
between the moving parts on the wrist should not be exposed to direct or rebounding high-
pressure jet of water.

Action
1. Connect a compressed air hose to
air connector on robot base.
2. Protect the screws on the Harting
connector on the robot base from
corrosion with Mercasol 3106.
3. Pressurize the robot.
4. Inspect the air system.
