4 Operating the DF6
This section describes how to take the DF6 frequency inverter into
operation and what you should observe during its operation.
Initial startup
Observe the following points before you take the frequency
inverter into operation:
• Make sure that the power lines L1, L2 and L3 and the frequency
inverter outputs U, V and W are connected correctly.
• The control lines must be connected correctly.
• The earth terminal must be connected correctly.
• Only the terminals marked as earthing terminals must be
earthed.
• The frequency inverter must be installed vertically on a non-
flammable surface (e.g. a metal surface).
• Remove any residue from wiring operations – such as pieces of
wire – and all tools from the vicinity of the frequency inverter.
• Make sure that the cables connected to the output terminals are
not short-circuited or connected to earth.
• Ensure that all terminal screws have been sufficiently tightened.
• Make sure that the frequency inverter and the motor are correct
for the mains voltage.
• The configured maximum frequency must match the maximum
operating frequency of the connected motor.
• Never operate the frequency inverter with opened power
section covers.
The control signal terminals are wired as follows.
X Switch on the supply voltage.
The POWER and Hz LEDs light up (keypad).
0.00 appears on the
display.
X Close switch S1 (FW = clockwise rotation).
X With potentiometer R1, you can set the frequency and therefore
the motor speed.
The motor turns clockwise and the display indicates the set
frequency.
X Open switch S1.
The motor speed is reduced to zero (display:
0.00).
X Close switch S2 (REV = anticlockwise operation).
X With potentiometer R1, you can set the frequency and therefore
the motor speed.
The motor turns anticlockwise and the display indicates the set
frequency.
X Open switch S2.
The motor speed is reduced to zero (display:
0.00).
If both switches S1 and S2 are closed, the motor will not start. If
you close both switches during operation, the motor speed is
reduced to zero.
Caution!
Do not carry out h.v. tests. Built-in overvoltage filters are
fitted between the mains voltage terminals and earth,
which could be destroyed.

Sparkover voltage and insulation resistance tests (megger
tests) have been carried out by the manufacturer.
