14 Safety instructions
WARNING!
If the measurement requires removal or disassembly of shrouding or
other cabinet structures, obey the local laws and regulations applicable to live
working (including – but not limited to – electric shock and arc protection).
6. Install temporary grounding as required by the local regulations.
7. Ask the person in control of the electrical installation work for a permit to work.
Additional instructions and notes
WARNING!
Obey these instructions. If you ignore them, injury or death, or
damage to the equipment can occur.
•
If you are not a qualified electrician, do not do electrical installation or maintenance
work.
•
We do not recommend that you secure the cabinet by arc welding. If you have to,
obey the instructions in the converter hardware manual.
•
Do not do insulation or voltage withstand tests on the converter or converter
modules.
•
Control boards of the converter unit may be at the main circuit potential. Dangerous
voltages can be present between the control boards and the frame of the converter
unit when the main circuit voltage is on. It is critical that the measuring instruments,
such as an oscilloscope, are used with caution and safety always as a priority. The
fault tracing instructions give special mention of cases in which measurements may
be performed on the control boards, also indicating the measuring method to be
used.
Note
:
•
The generator cable terminals on the converter are at a dangerously high voltage
when the converter is connected to the grid, regardless of whether the generator is
running or not.
•
The converter DC bus carries a dangerous voltage (over 500 V) when the converter
is connected to the grid or when the generator shaft is rotating.
•
External wiring can supply dangerous voltages to the terminals of relay outputs.
WARNING!
Use a grounding wrist band when you handle the printed circuit
boards. Do not touch the boards unnecessarily. The boards contain
components sensitive to electrostatic discharge.
