SAFETY INSTRUCTIONS
IMPORTANT!
Safety instructions showed in this manual are useful to teach user
how to use the product in a correct and safety way with the purpose
of preventing possible personal injuries or property damages.
Safety messages included here are classified as it follows:
WARNING
Be sure to take ESD (Electrostatic Discharge) protection measures
when you touch the board.
Otherwise, the optional board may get damaged due to static charges.
Implement wiring change on the optional board after checking that
the power supply is off.
Otherwise, connecting error and damage to the board could occur.
Be sure to connect correctly the optional board to the drive.
Otherwise, connecting error and damage to the board could occur.
Do not remove the cover while the power is applied or the unit is in
operation.
Otherwise, electric shock could occur.
Do not run the drive with the front cover removed.
Otherwise, you may get an electric shock due to the high voltage
terminals or exposure of charged capacitors.
Do not remove the cover except for periodic inspections or wiring,
even if the input power is not applied.
Otherwise, you may access the charged circuits and get an electric shock.
Operate the switches with dry hands.
Otherwise, you may get an electric shock.
Do not use cables with damaged insulation.
Otherwise, you may get an electric shock.
Do not subject the cables to abrasions, excessive stress, heavy
loads or pinching.
Otherwise, you may get an electric shock.

SAFETY INSTRUCTIONS
WARNINGS
RECEPTION
Material of Power Electronics is carefully tested and perfectly
packed before leaving the factory.
In the event of transport damage, please ensure that you notify
the transport agency and POWER ELECTRONICS: 902 40 20 70
(International [phone]) or your nearest agent, within
24hrs from receipt of the goods.
UNPACKING
Make sure received merchandise corresponds with delivery note,
models and serial numbers.
Each optional board is supplied with a technical manual.
RECYCLING
The packing of the boards must be recycled. For this reason it is
necessary to separate different materials (plastics, paper,
cardboard, wood …) and settle them in corresponding containers.
The residual parts of electrical devices must be collected in a
selective manner in order to warranty the correct environmental
treatment.

1. INTRODUCTION
This document is a mounting guide of the STO board (Safe Torque Off)
implemented on SD500 drives of Power Electronics.
Figure 1.1 STO Board
The STO function is defined as follows:
“Power, that can cause rotation, is not applied to the motor. The frequency
will not provide energy to the motor, which can generate torque.”
For three-phase asynchronous motors, that means to stop supplying
alternating tree-phase power to the stator.
This function corresponds with an Emergency Stop Category 0 according to
IEC 60204-1. When the drive is running and the STO function is applied, the
motor will freely stop by its own inertia.
Based on the study of each application and a risk assessment, the designer
should define the safety function required and each safety level. The STO
safety has been designed according to IEC/EN 61800-5-2.
The SD500’s STO optional board permits to achieve the safety integrity level
SIL2 (PLd).

DESCRIPTION
2.4. Operation Description
The SD500’s STO optional board permits to achieve two Safety Levels
for the STO function by using the two different channels SFT1 and
SFT2. Depending on the application, users can select the channel to
be used.
SFT1 channel operation (terminals 24S and SE)
When there is a safe stop event, the IGBTs switching stops in the
equipment and the control board continues operating normally,
showing the equipment’s speed. It is necessary to disconnect and
reconnect the equipment to delete this fault.
SFT2 channel operation (terminals 24S / SP and SR+ / SR-)
When there is a safe stop event, the rectifier bridge is disabled and the
relay contact of the STO board is opened (terminals SR+ and SR-).
Once this relay is opened, the equipment trips as F13 “External Trip”.
It is necessary to close again the 24S/SP circuit and reset the fault in
the equipment’s display to delete this fault.
Note: To ensure a correct operation of the SFT2 channel, the SR+ and
SR- terminals must be connected to a digital input of the equipment
and this digital input must be set as “EXT TRIP”.

3. INSTALLATION AND CONNECTION
The STO board is designed for the SD500 series. It is directly located on the
control board.
Install the STO board according to the following instructions.
CAUTION
Motor controllers of Power Electronics operate with AC and DC high
voltage.
Make sure the power supply has been disconnected guarantee that DC
Link voltage is discharged, before installing the STO board. Otherwise,
you may get personal injuries or an accident could occur.
Depending on the SD500 frame the connection between safety card and
the inverter should be done as follows:
1- Remove the front cover by unscrewing the bottom screw and the internal
cover by releasing the four brackets located in the equipment’s sides:
Figure 3.1 Front cover and inner cover removal
The next steps depend on the drive’s frame.
