• Disconnect the current supply before carrying out the following work:

- Installing or removing power units.

- Working in the immediate vicinity of open power supply components.

- Mechanical check of power supply components.

- Modifying circuits in the device.

• Test the zero potential of the device parts.

• Check the working area for possible sources of danger, such as wet oors, defective extension cables, defective

protective conductor connections.

Additional precautions in the case of exposed voltages:

• Ask a second person to remain near the working site. This person must know where the emergency and power

switches are, and how to switch the current off if danger arises.
