2. Safety
2.1. Safety Instructions
The following safety instructions male no claim to completeness. If you have any questions, uncertainties
or problems, please contact us.
2.1.1. Qualified personnel
All work such as transport, installation, commissioning and service may only be carried out by qualified
specialist personnel. Qualified specialist personnel are persons who are familiar with the transport, in-
stallation, assembly, commissioning and operation of the product and who have the qualifications re-
quired for their job. National accident prevention regulations must be observed. The safety instructions,
the information on the connection conditions (rating plate and documentation) and the limit values spec-
ified in the technical data must be read carefully before installation and commissioning and must be
strictly adhered to.
2.1.2. Documentation
Before installation and commissioning, please read this documentation as well as the documentation
which is referenced in their entirety. Incorrect handling can lead to personal injury or damage to prop-
erty. Be sure to comply with the technical specifications, connection conditions and environmental con-
ditions.
2.1.3. ESD- Schutz
The servo amplifiers contain electrostatically sensitive components that can be damaged by improper
handling. Discharge your body before touching the servo amplifiers. Avoid contact with highly insulating
materials (synthetic fibers, plastic films etc.). Place the servo amplifiers on a conductive surface in a volt-
age-free state. Do not touch the contacts of the connector on the drive and the connected cables or the
contact pins on the conductors.
2.1.4. Protection against contact with electrical components
For the operation of the servo amplifier it is necessary that certain parts carry voltages of more than
50VAC, exceeding extra-low voltage limit. If such parts are touched, life-threatening electric shocks may
occur. There is a risk of death or serious damage to health.
Before switching on a drive, make sure that the device is properly connected to the PE conductor. The
earth connection must always be connected, even if the drive is only put into operation for a short time.
Before switching on, live parts with more than 50VAC must be protected against direct contact by means
of suitable measures.
Connections can also carry dangerous voltages when the motor is not turning. Touching the terminals
when they are switched on is therefore prohibited. Before working on the drive, disconnect it from the
mains and secure it against being switched on again.
Contact with live parts (e.g. terminals) may result in death or serious health or material damage. Never
disconnect the electrical connections of the modules whilst live. In unfavorable cases, arcing can occur,
harming people and hardware such as contacts.

SAC4xX User Manual
01.04.2020 Rev 1.42en 14
2.1.5. Turn off
After switching off the mains supply, residual voltages can be present for several minutes. Measure the
intermediate circuit voltage and wait until the voltage has fallen below 50V.
2.1.6. High voltage test, insulation resistance test
Do not perform a high voltage test or an insulation resistance test on the mains connection and motor
connection of the drives, otherwise the drive will be damaged.
2.1.7. Residual Current Circuit Breaker (RCCB)
When this product is supplied by a 3phase mains supply, a defect can cause a DC Current at the protective
earth conductor. If an RCCB is installed in the grid connection system, only “RCCB Type B” are allowed.
Only type B universal current-sensitive Residual Current Circuit Breakers may be used.
2.1.8. Safe Torque off (STO)
The safety function STO as described in chapter 6 is designed as a safety pulse inhibitor. The drive may
restart after resetting the pulse inhibitor, depending on the application.
Activating the safety function is not suitable for de-energising the drive.
Activating the safety function does not provide protection against electric shock.
In case of multiple faults (hardware defects of power semiconductors inside the output power stage)
the motor can move a certain limited angle/distance even in the safe STO state. See chapter 2.1.9 for
more information.

SAC4xX User Manual
01.04.2020 Rev 1.42en 15
2.1.9. Maximum movement in the event of an error
It should be noted that a multiple fault in the IGBT bridge could cause the motor to advance for a short
period. The maximum rotational angle of the motor shaft or maximum linear distance occurring when
advancing depends on the number of pole pairs in the motor used.
For permanent-magnet synchronous servo motors:
For linear motors:
For DC-Motors:
DC-Motors connected to GIN-SAC4xX devices shall not be used for dangerous or safety relevant appli-
cations.
As a matter of principle the STO Safety-function can get completely ineffective when using DC-Motors in
case of faults in the IGBT bridge or the motor wiring.

2.2. Safety requirements
During the installation and operation of Indel Drives in applications with stop category 0 or 1 safety re-
lated Torque off of the drive according to EN 60204-1 and fail-safe protection against restart in accord-
ance with EN ISO 13849-1 cat. 3 / PL d, all conditions inside this Manual apply and all conditions that are
referred to apply, are compulsory and must be observed.
Indel servo drives with the STO function have been developed according to the relevant standards.
2.2.1. Risk analysis
The machine manufacturer must prepare a risk analysis for the machine and take appropriate measures
so that unforeseen movements do not lead to damage to persons or property.
There are also indications in this document regarding possible dangers. All information on dangers, warn-
ings, precautionary measures and information must be observed.
2.2.2. Checking the safety function
See chapter 6.5 “Monitoring of the diagnostic path (K1-K2) by the user”.
Periodic test cycle:
The EN 61800-5-2 2016 Standard defines the following maximum time between 2 test cycles depending
on the required safety Performance Level (PL) and Category:
For SIL 2, PL d Category 3 at least 1 test per year
For SIL 3, PL e Category 3 at least 1 test every 3 months
For SIL 3, PL e Category 4 at least 1 test per day
PL and Category as specified in ISO 13849-1.
2.2.3. Run-on
If application-dependent dangers arise as a result of the run-on, additional protective measures must be
taken (e.g. movable guards with locks), in order to cover the danger area until there is no danger to per-
sons or property. It must be taken into account that, without a mechanical brake or with a defective
brake, drive run-on is possible.
2.2.4. Braking or Ballast resistance
The braking resistor is not safely controlled by the Indel servo drives. A defective or improperly connected
braking resistor will cause the motor to stop outside the expected timespan. In the worst case, this can
lead to personal injury and damage to property.

2.2.5. Residual energy in the DC intermediate circuit
Residual charge in the intermediate circuit capacitors can be retained for up to 10 minutes after switching
off the power supply (opening the main contactor or motor contactor). It is possible to move the motor
with this residual charge. This can potentially lead to dangerous situations. If additional external capaci-
tor modules are used, it will take longer for the intermediate circuit capacitors to discharge.
The following warning is attached to the drives.
2.2.5.1 Hot Surface
Under high load the device will run hot and some parts of the case reach temperatures up to 80°C.
Warning: Risk of burn.
The following warning is attached to the drives
2.2.6. Safety covers
Additional safety covers must be designed and integrated in accordance with the safety category re-
quired for the machine according to EN ISO 13849-1. After the stop command has been triggered, de-
pending on the danger posed, access must remain locked until the drive has come to a complete stop.

2.2.7. Protection against dangerous movements
Incorrect activation of motors can trigger unintended and dangerous movements.
Incorrect installation
Faulty design
Faulty or incomplete wiring
Defective devices or cables
Incorrect control by the software
As a rule, after switching on the drive, motor movement is to be expected. Protection of persons and ma-
chines can only be guaranteed by means of overarching measures. Suitable measures are to be taken in
order to protect the range of motion of machinery against unintentional access by people. Removing,
bridging, or bypassing safety devices is strictly prohibited. A sufficient number of easily accessible Emer-
gency Power Off switches is to be attached to the machine. Keep all covers and cabinet doors closed dur-
ing operation.
2.2.8. Suspended loads
In the case of suspended loads, addition measures must be taken in order to ensure that the axis stays in
place. The Indel servo drives do not offer any outputs which allow you to safely control securing brakes.
Holding brakes provide no protection when slowing down the motor.
2.2.8.1 Loss of the logic power supply
If the 24V logic power supply fails on the drive, the motor may spin out. If this is not permitted, external
measures must be taken to prevent the axis from spinning out.
2.2.9. Power failure of themains supply
In the event of a power failure of the mains supply or the supply for the motors, the motor may spin out. If
the intermediate circuit voltage Ucc drops below the configured limit Ucc MIN, the servo drive will signal
an error and the motors will be deactivated.
2.2.10. EMC
For EMC-compliant wiring, see further document INDEL Wiring Guidelines and INDEL installation Guide-
line and all wiring instructions in this document.
INDEL Wiring Guidelines
INDEL Installation Guideline (only available in German)
The machine or system manufacturer must take additional measures for EMC protection if the product
standard contains lower limit values applicable to the machine in question. In the case of machines
which contain many Indel servo drives, additional EMC protection measures may also be required.
The Gin-SAC4 devices are intended for use in industrial environment. A line filter is required on the mains
connection preceding the GIN-SAC4. See also chapter 8.10.2
In a residential environment (first environment), this product may cause high frequency interference,
which may require further suppression measures.

2.2.11. Commissioning
Before switching on a servo drive, make sure that the device is properly connected to earth. The earth
connections must always be provided, even if the drive is only put into operation for experimental pur-
poses.
Control and power connections can carry voltage even when the motor is not moving. Touching the
terminals when the power is on is prohibited. Before working on the drives, they must be disconnected
from the mains and secured against being switched on again.
Documented commissioning and demonstration of the safety functions must take place. For Indel servo
drive applications with stop category 0 or 1 safety-related cut-out of the drive according to EN 60204-1
and fail-safe protection against restart in accordance with EN ISO 13849 cat. 3, commissioning of the cut-
out mechanism and the correct wiring must always be carried out and recorded.
During commissioning, signal detection must be included in the functional test. The status of the auxiliary
contacts of the safety relays can be viewed in the “actual parameters”in the servo drive. However, these
contacts and displayed values are for diagnostic purposes only and not part of the safety function.
2.2.12. Service life
Fifteen years after delivery at the latest, the safety module in the servo drives must be replaced. If used
for more than 15 years, safe operation is no longer guaranteed. This applies not only to the operating
time, but also to standstill and storage time.
2.2.13. Simple protection against bypassing
Measures must be taken to prevent bypassing of the safety functions in accordance with EN ISO 138491
Cat.3 / PL d.
2.2.14. Responsibility
The servo drives are not completely fail-safe. In the event of a failure, the operator is responsible for en-
suring that the machine / system is put into a safe condition.
All of the diagnostic and monitoring functions can only interrupt the control of the motor. As a conse-
quence of this, the motor is de-energised and can no longer be controlled and braked. Depending on the
application, additional measures may be required to slow down or stop the motor.
The operator is responsible for safety.
2.2.15. Defective drives
Defective and damaged drives must under no circumstances be taken into operation. This can lead to
serious personal injury and property damage.
