2 Safety information
2.1 General safety notes
This chapter contains general safety information about the safety controller.
Further safety information is provided in the respective chapters to cover the specific
situations in which the product may be used.
DANGER
If the device is not integrated in the way intended by the manufacturer, the protective
function of the device can be impaired. The dangerous state may be ended too late.
bPlan the integration of the safety component in accordance with the machine
requirements, see "Project planning", page 13.
2.2 Intended use
The Flexi Compact safety controller is a freely configurable control for safety applica‐
tions. Sensors and switching elements (e.g. light curtains, laser scanners, switches,
sensors, encoders, emergency stop pushbuttons) are connected to the safety controller
and are linked logically. The corresponding actuators of the machines or systems can
be switched off safely via the switching outputs of the safety controller.
Incorrect use, improper modification or manipulation of the module will invalidate any
warranty from SICK; in addition, any responsibility and liability of SICK AG for damage
and secondary damage caused by this is excluded.
The safety controller system is only suitable for use in industrial environments.
2.3 Improper use
Among others, the safety controller is not suitable for the following applications:
•Outdoors
•Underwater
•In explosion-hazardous areas
•In residential areas
2.4 Requirements for the qualification of personnel
The protective device must be configured, installed, connected, commissioned, and
serviced by qualified safety personnel only.
Project planning
For project planning, a person is considered competent when he/she has expertise and
experience in the selection and use of protective devices on machines and is familiar
with the relevant technical rules and national work safety regulations.
Mechanical mounting, electrical installation, and commissioning
For the task, a person is considered qualified when he/she has the expertise and
experience in the relevant field and is sufficiently familiar with the application of the
protective device on the machine to be able to assess whether it is in an operationally
safe state.

4.1 Manufacturer of the machine
DANGER
Failure to comply with manufacturer’s obligations
Hazard due to lack of effectiveness of the protective device
bCarry out a risk assessment before using the safety controller.
bDo not manipulate, open or modify the components of the safety controller.
bMake sure the safety controller is only repaired by the manufacturer or by some‐
one authorized by the manufacturer. Improper repair can lead to a loss of the
protective function.
4.2 Operating entity of the machine
DANGER
Failure to observe operator obligations
Hazard due to lack of effectiveness of the protective device
bChanges to the machine and changes to the hardware or the logic programming
of the safety controller necessitate a new risk assessment. The results of this risk
assessment may require the entity operating the machine to meet the obligations
of a manufacturer.
bApart from the procedures described in this document, the components of the
safety controller must not be opened or modified.
bDo not carry out any repair work on components. Improper repair of the safety
controller can lead to a loss of the protective function.
4.3 Design
Mounting
•Environment meets the requirements of IP54 or higher, e.g., IP54 control cabinet.
•Mounting on a 35 mm × 7.5 mm mounting rail in accordance with IEC 60715.
•The mounting rail is connected to the functional earth.
•Mounting rail is mounted on a mounting plate.
•Mounting plate is connected to functional earth.
•Mounting in a vertical orientation (on a horizontal mounting rail).
•Take suitable ESD protection measures.
Air circulation
To ensure sufficient air circulation and cooling, sufficient distance must be kept in the
control cabinet above and below the module.
Provide an adequate clearance in front of the module (front side) for the connected
cables.

Important information
WARNING
Ineffectiveness of the protective device
In the event of a fault, a single safety output (Q) can switch off after a delay or briefly
switch to High. The response time increases depending on the configuration of the
output. The dangerous state may not be stopped or not be stopped in a timely manner
in the event of non-compliance.
bTake the increased response time into consideration in the risk analysis.
bTake the possible reduced safety level into consideration in the risk analysis.
Fault detection by testing
The following faults can be detected by testing an element:
•Short-circuits between any of the safety outputs.
You can detect a cross-circuit between the safety outputs of 12 sequential mod‐
ules.
•Short circuits to 24 V DC (to High) on safety outputs.
•Actuator wiring short-circuits to 24 V.

4.5 Testing plan
Testing plan
The manufacturer of the machine and the operating entity must define all required
thorough checks. The definition must be based on the application conditions and the
risk assessment and must be documented in a traceable manner.
In addition, the device must be checked for correct functioning after each change to the
configuration.
bWhen defining the thorough check, please note the following:
°Define the type and execution of the thorough check.
°Define the frequency of the thorough check.
°Notify the machine operators of the thorough check and instruct them
accordingly.
The following thorough checks are often defined in connection with a protective device:
•Thorough check during commissioning and modifications
•Regular thorough check
Thorough check during commissioning and modifications
The following points are helpful when planning the thorough check:
•Does the thorough check have to be completed by qualified safety personnel?
•Can the thorough check be completed by personnel specially qualified and autho‐
rized to do so?
•Does the thorough check have to be documented in a traceable manner?
•Can the thorough check be carried out according to a check list?
•Do the machine operators know the function of the protective device?
•Have the machine operators been trained to work on the machine?
•Have the machine operators been notified about modifications to the machine?
bDefine all guidelines for the thorough check.
Regular thorough check
The following points are helpful when planning the thorough check:
•Which thorough check must be carried out and how is it carried out?
•How often does the thorough check have to be carried out?
•Do the machine operators have to be notified of the thorough check and do they
need to be instructed accordingly?
bDefine all guidelines for the thorough check.

•The mounting rail is connected to the functional earth.
•The voltage supply and connected signals meet the requirements for extra-low
voltages with safe separation (EN 60664) or NEC Class 2 (UL 1310).
•The external voltage supply must be capable of buffering brief power failures of
20 ms as specified in EN 60204-1. Suitable power supply units are available as
accessories from SICK.
•The GND of all connected devices must have the same potential as A2 of the main
module. Exceptions are actuators which are connected to an expansion module
with its own voltage supply.
•The GND connections of the actuators to the safety outputs are in star formation
with the GND connection of the voltage supply.
