2 Installation and commissioning
2.6.1. Installation of IRB4400 in a water jet application
Continued
Pressurize the motors 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.
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 from high pressure water
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.
Protecting the wrist joints
The sealings between the moving parts on the wrist should not be exposed to direct high-
pressure water. We recommend that the gripper include a shield that prevents direct water
flush on the sealing surfaces of the wrist. The sealings are pointed out in the illustration
below.

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