6.1 General Notes on Starting and Operating
DANGER
Risk of electric shock if the protective earth conductor is not connected!
If a protective earth conductor is not or not properly connected, dangerous touch voltages can
occur on the P-2x5 in the case of malfunction or failure of the system. If there are touch
voltages, touching the P-2x5 can result in serious injury or death from electric shock.

Connect the P-2x5 to a protective earth conductor (p. 22) before starting.

Do not remove the protective earth conductor during operation.

If the protective earth conductor has to be removed temporarily (e.g., in the case of
modifications), reconnect the P-2x5 to the protective earth conductor before restarting.
CAUTION
Burning due to hot surface!
The surface of the P-2x5 can heat up during operation. Touching the P-2x5 can lead to minor
injuries from burning.

Cool the P-2x5, for example, with purge air (p. 25) so that the temperature of the surface
does not exceed 65 °C.

If sufficient cooling is not possible: Make sure that the hot P-2x5 cannot be touched.

If sufficient cooling and protection against contact are not possible: Mark the danger zone
in accordance with the legal regulations.
