SAFETY
Before operating the drive, read this manual thoroughly to gain and understanding of the unit. If
any doubt exists then please contact POWER ELECTRONICS, (902 40 20 70 / +34 96 136 65
57) or your nearest agent.
Wear safety glasses when operating the drive with power applied or the front cover is removed.
Handle and transport the drive following the recommendations within this manual.
Install the drive according to the instructions within this manual and the local regulations.
Do not place heavy objects on the drive.
Ensure that the drive is mounted vertically and keeping the minimum clearances distances.
Do not drop the drive or subject it to impact.
The SD700FL drives contain static sensitive printed circuits boards. Use static safety procedures
when handling these boards.
Avoid installing the drive in conditions that differ from those described in the
Technical
Characteristics
section.
CONNECTION PRECAUTIONS
To ensure correct operation of the drive it is recommended to use a SCREENED CABLE for the
control wiring.
The motor cable should comply with the requirements within this manual. Due to increased
leakage capacitance between conductors, external ground fault protection threshold value
should be adjusted ad hoc.
Do not disconnect motor cables if input power supply remains connected.
The internal circuits of the SD700 Series will be damaged if the incoming power is connected
and applied to output terminals (U, V, W).
Do not use power factor correction capacitors banks, surge suppressors, or RFI filters on the
output side of the drive. Doing so may damage these components.
Always check whether the DC Link red LED is OFF before wiring terminals. The capacitors may
hold high-voltage even after the input power is disconnected.
TRIAL RUN
Verify all parameters before operating the drive. Setting of parameters may be required
depending on application and load.
Always apply voltage and current signals to each terminal that are between levels indicated
within this manual.
OPERATION PRECAUTIONS
When the Auto Restart function is enabled, keep clear of driven equipment, as the motor will
restart suddenly after the fault reset.
The “STOP / RESET” key on the keypad is active only if the appropriate function setting has
been made. Pushing this button the drive will NOT perform a safe stop. It is available STO
optional board, which installed with an external EMERGENCY STOP pushbutton, will disconnect
the motor power supply and will be unable to generate torque in the motor with high reliability.
If a fault is reseted with the reference signal still active, the drive will unexpectedly restart. Verify
that it is permissible for this to happen. Otherwise, it could cause a personal injury.
Do not modify or alter internal wiring and spare parts without Power Electronics supervision.
Before programming or operating the SD700 Series, initialise all parameters back to factory
default values.
