Introduction 1
1.1 About SIDOOR
What is SIDOOR?
The SIDOOR product series is a door control system mainly for operation of sliding doors as well
as lifting and roller doors. SIDOOR door drives are drives for doors and gates in various areas of
application.
What is a door control system?
Door control system is the general term for the controller of an access system.
Door control systems are characterized by the fact that there are always two de󹪝ned states,
namely for the open and closed positions of the door. The door is always controlled between
these two positions in accordance with the guidelines of the respective application.
SIDOOR for elevators
The SIDOOR door control systems for elevators are intelligent solutions that allow the opening
and closing of cabin and shaft doors with adjustable speeds, accelerations and forces.
Customer bene󹪝ts
• The controllers are optimally con󹪝gured for their areas of application. With SIDOOR, doors
are always checked and controlled in an application-speci󹪝c manner.
• Our intelligent system solution calculates the optimal drive characteristics for a door
automatically, and ensures that these are continuously maintained – in accordance with the
guidelines of the application.
• The entire commissioning process requires just the push of a single button. In a de󹪝ned learn
run, the door system independently determines the values for the door width, the dynamic
mass to be moved and the drive direction of the geared motor, and stores this data in a non-
volatile memory.
• The screwless enclosure concept, with pluggable terminal connections, allows the device to
be opened and closed without tools, thereby reducing installation times.
• The system's reliability, ruggedness and long-term precision minimize the need for
maintenance and repair work. Obstruction and belt tear detection provides more safety.

Fundamental safety instructions 2
2.1 General safety instructions
WARNING
Electric shock and danger to life due to other energy sources
Touching live components can result in death or severe injury.
• Only work on electrical devices when you are quali󹪝ed for this job.
• Always observe the country-speci󹪝c safety rules.
Generally, the following steps apply when establishing safety:
1. Prepare for disconnection. Notify all those who will be a󹪜ected by the procedure.
2. Isolate the drive system from the power supply and take measures to prevent it being
switched back on again.
3. Wait until the discharge time speci󹪝ed on the warning labels has elapsed.
4. Check that there is no voltage between any of the power connections, and between any of
the power connections and the protective conductor connection.
5. Check whether the existing auxiliary supply circuits are de-energized.
6. Ensure that the motors cannot move.
7. Identify all other dangerous energy sources, e.g. compressed air, hydraulic systems, or
water. Switch the energy sources to a safe state.
8. Check that the correct drive system is completely locked.
After you have completed the work, restore the operational readiness in the inverse sequence.
WARNING
Risk of electric shock and 󹪝re from supply networks with an excessively high impedance
Excessively low short-circuit currents can lead to the protective devices not tripping or tripping
too late, and thus causing electric shock or a 󹪝re.
• In the case of a conductor-conductor or conductor-ground short-circuit, ensure that the
short-circuit current at the point where the converter is connected to the line supply at least
meets the minimum requirements for the response of the protective device used.
• You must use an additional residual-current device (RCD) if a conductor-ground short circuit
does not reach the short-circuit current required for the protective device to respond. The
required short-circuit current can be too low, especially for TT supply systems.
AT40 and ATD400V for elevators
System Manual, 06/2022, A5E42192709-AH 15

WARNING
Risk of electric shock and 󹪝re from supply networks with an excessively low impedance
Excessively high short-circuit currents can lead to the protective devices not being able to
interrupt these short-circuit currents and being destroyed, and thus causing electric shock or a
󹪝re.
• Ensure that the prospective short-circuit current at the line terminal of the converter does
not exceed the breaking capacity (SCCR or Icc) of the protective device used.
WARNING
Electric shock if there is no ground connection
For missing or incorrectly implemented protective conductor connection for devices with
protection class I, high voltages can be present at open, exposed parts, which when touched,
can result in death or severe injury.
• Ground the device in compliance with the applicable regulations.
WARNING
Electric shock due to connection to an unsuitable power supply
When equipment is connected to an unsuitable power supply, exposed components may carry
a hazardous voltage. Contact with hazardous voltage can result in severe injury or death.
• Only use power supplies that provide SELV (Safety Extra Low Voltage) or PELV- (Protective
Extra Low Voltage) output voltages for all connections and terminals of the electronics
modules.
WARNING
Electric shock due to equipment damage
Improper handling may cause damage to equipment. For damaged devices, hazardous
voltages can be present at the enclosure or at exposed components; if touched, this can result
in death or severe injury.
• Ensure compliance with the limit values speci󹪝ed in the technical data during transport,
storage and operation.
• Do not use any damaged devices.

WARNING
Electric shock due to unconnected cable shield
Hazardous touch voltages can occur through capacitive cross-coupling due to unconnected
cable shields.
• As a minimum, connect cable shields and the conductors of power cables that are not used
(e.g. brake cores) at one end at the grounded housing potential.
WARNING
Arcing when a plug connection is opened during operation
Opening a plug connection when a system is operation can result in arcing that may cause
serious injury or death.
• Only open plug connections when the equipment is in a voltage-free state, unless it has
been explicitly stated that they can be opened in operation.
WARNING
Electric shock due to residual charges in power components
Because of the capacitors, a hazardous voltage is present for up to 5 minutes after the power
supply has been switched o󹪜. Contact with live parts can result in death or serious injury.
• Wait for 5 minutes before you check that the unit really is in a no-voltage condition and start
work.
NOTICE
Damage to equipment due to unsuitable tightening tools.
Unsuitable tightening tools or fastening methods can damage the screws of the equipment.
• Only use screw inserts that exactly match the screw head.
• Tighten the screws with the torque speci󹪝ed in the technical documentation.
• Use a torque wrench or a mechanical precision nut runner with a dynamic torque sensor and
speed limitation system.
• Adjust the tools used regularly.
NOTICE
Property damage due to loose power connections
Insu󹪟cient tightening torques or vibration can result in loose power connections. This can
result in damage due to 󹪝re, device defects or malfunctions.
• Tighten all power connections to the prescribed torque.
• Check all power connections at regular intervals, particularly after equipment has been
transported.

WARNING
Spread of 󹪝re from built-in devices
Built-in devices can cause a 󹪝re and a pressure wave in the event of a fault. Fire and smoke can
escape from the control cabinet and cause serious personal injury and property damage.
• Install built-in appliances in a robust metal control cabinet that is suitable for protecting
people from 󹪝re and smoke.
• Only operate built-in devices with the control cabinet doors closed.
• Ensure that smoke can only escape via controlled and monitored paths.
WARNING
Active implant malfunctions due to electromagnetic 󹪝elds
Converters generate electromagnetic 󹪝elds (EMF) in operation. Electromagnetic 󹪝elds may
interfere with active implants, e.g. pacemakers. People with active implants in the immediate
vicinity of an converter are at risk.
• As the operator of an EMF-emitting installation, assess the individual risks of persons with
active implants.
• Observe the data on EMF emission provided in the product documentation.
WARNING
Unexpected machine movement caused by radio devices or mobile phones
Using radio devices, cellphones, or mobile WLAN devices in the immediate vicinity of the
components can result in equipment malfunction. Malfunctions may impair the functional
safety of machines and can therefore put people in danger or lead to property damage.
• Therefore, if you move closer than 20 cm to the components, be sure to switch o󹪜 radio
devices, cellphones or WLAN devices.
• Use the "SIEMENS Industry Online Support app" only on equipment that has already been
switched o󹪜.
NOTICE
Damage to motor insulation due to excessive voltages
When operated on systems with grounded line conductors or in the event of a ground fault in
the IT system, the motor insulation can be damaged by the higher voltage against ground. If
you use motors that have insulation that is not designed for operation with grounded line
conductors, you must perform the following measures:
• IT system: Use a ground fault monitor and eliminate the fault as quickly as possible.
• TN or TT systems with grounded line conductor: Use an isolating transformer on the line
side.
