2 Safety
2.1 Electrical
Warning
Danger
Risk of electric shock from charged capacitors
Always disconnect the system from the power
supply and then wait a further 10 minutes before
touching electrical components. The power
capacitors require this time to discharge.
Check the DC bus voltage at the system terminal
strip of the frequency converter by measuring this
between
1) the +DC and -DC terminals (the exact position
can be found in the operating manual supplied
for the frequency converter),
2) between the +DC terminal and the chassis, as
well as
3) between the -DC terminal and the chassis.
The voltage must read zero in all three
measurements.
2.2 Safety
Guidelines
This operating manual exclusively describes the control
unit. It contains important references and warnings, and
therefore should be read by the relevant operator as
well as by the installer before installing and operating
the unit.
Note
Not only should the general safety references
mentioned in this “Safety guidelines” chapter be
observed, but also any special safety references
referred to in the other sections of the manual.
2.3

specific indications in this regard.
If any of the regulations contained in these instructions
