SAFETY INSTRUCTIONS

SAFETY
•
Before operating the drive, read this manual thoroughly to gain an understanding of the unit. If any
doubt exists, 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 for when 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 clearance distances.
•
Do not drop the drive or subject it to impact.
•
The SD750 Kompakt drives contain static sensitive printed circuits boards. Use anti-static safety
procedures when handling these boards.
•
Avoid installing the drive in conditions that differ from those described in the Environmental Ratings
section.
CONNECTION PRECAUTIONS
•
To ensure a 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, the external ground fault protection threshold value
should be adjusted ad hoc.
•
Do not disconnect motor cables if the input power supply remains connected.
•
The internal circuits of the SD750 Kompakt 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.
•
Do not connect the drive in grids whose THDv is higher than 8%.
COMMISSIONING
•
Verify all parameters before operating the drive. Alteration of parameters may be required
depending on application and load.
•
Always apply voltage and current signals to each terminal that are within the levels indicated in
this manual. Otherwise, damage to the drive may occur.
•
For correct starting, refer to the start-up section.
HANDLING PRECAUTIONS
•
When the "Automatic Restart" function is selected, observe the appropriate safety measures to
avoid any damage in case of sudden restart of the motor after an emergency and subsequent
reset.
•
The "STOP / RESET" key on the driver's own keypad will be operative as long as this option has
been selected. By pressing this button, the drive will not perform an emergency stop. The driver
has a STO function which, installed with an external EMERGENCY pushbutton, will disconnect
the motor power supply and prevent the ability to generate torque in the motor.
•
If an alarm is reset without having lost the reference signal (setpoint), an automatic start may
occur. Check that the system has not been configured as such. Failure to do so could result in
personal injury.
•
Do not modify anything inside the driver without the supervision of Power Electronics.
•
Before starting the parameter setting, reset all parameters.
