Safety for Maintenance

The purpose of maintenance and repair is to ensure the system is kept functioning as expected.

When working on the robot arm or control box, you must observe the procedures and warnings below.

Failure to adhere to any of the safety practices, listed below, can result in injury.

  • Unplug the main power cable from the bottom of the Control Box to ensure that it is completely unpowered. Power off any other source of energy connected to the robot arm or Control Box. Take necessary precautions to prevent other persons from powering on the system during the repair period.

  • Check the earth connection before re-powering the system.

  • Observe ESD regulations when parts of the robot arm or Control Box are disassembled.

  • Prevent water and dust from entering the robot arm or Control Box.

Safety for Maintenance

Failure to leave space to accommodate the Control Box with the door fully open can lead to injury.

  • Provide at least 915 mm of space to enable the Control Box door to open fully, providing access for servicing.

Disassembling the Control Box power supply too quickly after switching off, can result in injury due to electrical hazards.

  • Avoid disassembling the power supply inside the Control Box, as high voltages (up to 600 V) can be present inside these power supplies for several hours after the Control Box has been switched off.

After troubleshooting, maintenance, and repair work, ensure that safety requirements are fulfilled. Adhere to national or regional work safety regulations. The correct functioning of all safety function settings shall also be tested and validated.
