Dangerous voltages
High voltages can cause death or serious injury if the safety rules are not observed or if the
equipment is handled improperly.
As soon as the DC link or the battery is connected, dangerous DC voltages are present.
When the SINAMICS DCP is in operation, high voltages occur, and can remain present for
a longer period after the equipment is switched off.
Make sure that work is only carried out by qualified personnel under strict observance of
the five safety rules, the warning notices in this documentation, and the safety-relevant
instructions.
Capacitor discharge / dangerous voltages
After disconnection of the supply voltage, voltages are still present in the SINAMICS DCP
devices that could result in death or serious injury.
After you have switched off the power supply, strictly observe the discharge time of the DC
link capacitors of 5 minute before you perform any maintenance work or repair work and do
not touch the device during this period.
Measure the voltage once the discharge time has elapsed.
Hot surfaces
During operation, the temperature of some components increases significantly; for
example, heat sinks, reactors, semiconductor modules etc.
These components can remain very hot for some time after operation. Serious injury
(scalding) may occur if you come into contact with these components.
Do not touch hot components even after you have switched off the SINAMICS DCP.
