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 / [phone]
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 SD700 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 SD700 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.

SAFETY INSTRUCTIONS
OPERATION PRECAUTIONS
When the Auto Restart function is enabled, keep clear of driven equipment, as the motor will
restart suddenly after a fault is reset.
The “STOP / RESET” key on the keypad is active only if the appropriate function setting has been
made. For this reason, install a separate EMERGENCY STOP push button that can be operated
at the equipment.
If a fault reset is made with the reference signal still present then a restart will occur. Verify that it
is permissible for this to happen, otherwise an accident may occur.
Do not modify or alter anything within the drive.
Before programming or operating the SD700 Series, initialise all parameters back to factory
default values.
EARTH CONNECTION
The drive is a high frequency switching device and leakage current may flow. Ground the drive to
avoid electrical shock. Use caution to prevent the possibility of personal injury.
Connect only to the dedicated ground terminal of the drive. Do not use the case or the chassis
screw for grounding.
When installing, grounding wire should be connected first and removed last.
The earth cable must have a minimal cross sectional area that meets local country electrical
regulations.
Motor ground must be connected to the drive ground terminal and not to the installation‟s ground.
We recommend that the section of the ground connection cable should be equal or higher than
the active conductor.
Installation ground must be connected to the drive ground terminal.

DESCRIPTION OF PROGRAMMING PARAMETERS
3.2. Group 4 –G4: Inputs
3.2.1. Subgroup 4.1 –S4.1: Digital Inputs
Pumps program activation, in G1.7 PROG = PUMP, requires the following considerations:
Some configuration options are available when the pump program is active, which can be set in the same
way that the options available in the standard program.
Nevertheless, when the pump program is active, the drive will assume that only the configurable options
from 50 to 75 (for G4.1.5 to G4.1.10) can be set, without taking into consideration the setting on parameter
„G4.1.4 DIGIT I MODE‟, which means a block setting.
This means that the user will configure the pump program freely, according to his requirements, selecting
the correct functionality and protections. For a correct programming of the digital inputs when the pump
program is active, there is additional information in G25 Pump Control.
Note: Digitial outputs should be configured in order to provide an optimum performance.
The following instructions should be followed:
oStep 1: Set the digital input 1 to the „50PMP.START/STP] option.
oStep 2: Whenever the user requires the use of PID multireferences, the user must carry
out the following configuration in the order described: set the digital output 2 as ‟63
SETPONT PIN1‟, the digital output 3 as ‟64 SETPONT PIN2‟ and the digital output 4 as
‟65 SETPONT PIN3‟.
oStep 3: Once steps 1 and 2 have been succesfully completed, the user may proceed
with the required functions programming.
Note: Selection of the pump program will set all the Digital Inputs to mode „00 – un used‟. If re-
programming is needed, it will be necessary to configure their functionality in a separate way again. So it
guarantees a safety installation operation, avoiding that hardware external to the equipment can cause any
kind of damage.
Note: The digital outputs will also be affected due to pump control activation.
To select one auxiliary pump it is necessary to act in the following way (If you do not want to
connect the input of auxiliary pump Fault Skip to step 2 directly) :
oStep 1: Set any free digital input to options „52 FIX PUMP1 FLT‟, „53 FIX PUMP2 FLT‟,
„54 FIX PUMP3 FLT‟, „55 FIX PUMP4 FLT‟ or „56 FIX PUMP5 FLT‟
oStep 2: To enable the control of the pump in the corresponding screen G25.9.1,
G25.9.2, G25.9.3, G25.9.4 and G25.9.5 respectively.
To remove this pump configuration and release the relay for another use, the user should:
oDisable the control of the pump in the corresponding screen G25.9.1, G25.9.2, G25.9.3,
G25.9.4 or G25.9.5 respectively.
