There is a danger of short-circuiting of the capacitors and battery, even when no
electrical power is applied to the device. If the main switch is switched off and the
power supply is connected, the internal battery is charged, electrical power is still
applied to the device!

Repair and maintenance tasks may only be carried out by suitably qualified,
authorized and competent personal.
