If the main circuit of the converter unit is live, the output terminals are also live
even if the converter stage is not modulating.
•
The brake control terminals (UDC+, UDC-, R+ and R- terminals) are at
dangerous DC voltage.
•
Depending on the external wiring, dangerous voltages (115 V, 220 V or 230 V)
can be present on the relay outputs of the converter system.
•
The Prevention of Unexpected Start function does not remove the voltage from
