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 and the front
cover is removed.
Handle the drive with care according to its weight.
Install the drive according to the instructions within this manual.
Do not place heavy objects on the drive.
Ensure that the mounting orientation is correct.
Do not drop the drive or subject it to impact.
The SDRIVE 700 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.
For EMERGENCY STOP, make sure supply circuitry is open.
Do not disconnect motor cables if input power supply remains connected. The
internal circuits of the SDRIVE 700 series will be damaged if the incoming power
is connected and applied to output terminals (U, V, W).
It is not recommended to use a 3-wire cable for long distances. Due to increased
leakage capacitance between conductors, over-current protective feature may not
operate correctly.
Do not use power factor correction capacitors, surge suppressors, or RFI filters on
the output side of the drive. Doing so may damage these components.
Always check whether the DC Link LED is OFF before wiring terminals. The
capacitors may hold high-voltage even after the input power is disconnected. Use
caution to prevent the possibility of personal injury.
TRIAL RUN
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 levels
indicated within this manual. Otherwise, damage to the drive may result.
