The hazard is:
Electricity.
The unit carries dangerous voltages and currents, as well as re-
sidual charges in the DC-link.
Assure, that when working in the switching cabinet, that all electrical terminals in the switching
cabinet are off-circuit and are safe against reclosing.
Await the discharge of the DC-link, before you carry out demounting works. The capacitors
which are used in the device are
10 min.
after interruption of the supply voltage automatically
discharge so far, that the terminals can be demounted without danger.
If you have additional capacitors connected to the DC-link, the DC-link decharging also can
last much longer. In this case you must determine the necessary waiting time yourself.
Before working, check at the electrical connections with suitable measuring devices, that the
connections are off-circuit.
Demount the connections not until you have verified yourself from the safe isolation of the
supply.
11.2 Requirements to the executing personnel
The personnel which you instruct to demount the device must have the knowledge and
training to carry out these works properly. Select the personnel in such a way, that the
safety instructions, which are mounted to the device and its parts as well as to the termi-
nals, are understood and applied to.
