2.3 Safety instructions for safety-related applications
Turn off and lock out all power supplying this device before working on this device.
In continuous operation, the key safety values apply in the case of a function test interval
(state change of the outputs) ≤ 1 year.
• Actuate the connected sensors.
• Check their effect on the safety relay and the downstream actuators.
• Activate the safety relay via the connected sensors.
• Check their effect on the safety relay and the downstream actuators.
• Defective devices must be replaced.
The control signal for the control inputs in the case of 3RM11/3RM13 Failsafe motor
starters with 110 to 230 V AC control supply voltage must come from A1. Otherwise, the
safety function is bypassed in the event of a fault. Thus, only relay outputs are admissible
when using a PLC.
Do not use a separate control voltage. Only use the relay outputs when using a PLC.
When the product is operated with a 3SK safety relay and a device connector, the supply
voltage for 3RM1 motor starters is fed in via the device connectors.
In this case, do not connect anything to terminals A1 and A2 of the 3RM1 motor starters, in
order to prevent bypassing of the safety function.

Overview
The 3RM1 motor starter is a compact device with a width of 22.5 mm. The 3RM1 motor
starter comprises combinations of relay contacts, power semiconductors, and a solid-state
overload relay for switching three-phase motors up to 3 kW (at 400 V) and resistive loads up
to 10 A (at AC voltages to 500 V) under normal operating conditions.

Description
3.2
Applications
3.2 Applications
The 3RM1 motor starters can be used wherever combinations of contactors and overload
relays were previously used.
Thanks to the additional functionality of safety-related shutdown, the 3RM11 Failsafe and
3RM13 Failsafe motor starter variants are ideally suited to safety-related applications up to
SILCL 3 in accordance with EN 62061 and PL e/Cat. 4 in accordance with EN ISO 13849-1.
Short-circuit protection in a load feeder designed in this way must be implemented by
appropriate upstream short-circuit protection devices. These can be, for example, circuit
breakers or appropriate fuses.
You achieve maximum space-savings benefits by means of a group configuration of the
3RM1 motor starters. This enables several 3RM1 motor starters to be protected by one
short-circuit protection device.
The 3RM1 motor starters are used in the following areas, for example:
● Conveyor technology
● Logistics systems
● Production machines
● Machine tools
● Small elevators

3.3 Hybrid technology
The 3RM1 motor starter combines the benefits of semiconductor technology and relay
technology.
This combination is known as hybrid technology. The hybrid technology in the 3RM1 motor
starter is characterized by the following features:
The inrush current in the case of motorized loads is conducted briefly via the
semiconductors.
Advantage: The relay contacts are protected. Longer service life is achieved thanks to
reduced wear and tear.
The continuous current is conducted via relay contacts.
Advantage: Relay contacts cause less thermal losses than semiconductors.
Switch-off is implemented again via the semiconductor.
Advantage: The contacts are only slightly burdened by arcs. This results in increased service
life.

3.3 Hybrid technology
The semiconductors switch the motor on and off in two phases. In the switched-off state, all
three phases are opened by a relay contact.
To achieve the highest safety level SILCL 3 in accordance with EN 62061, PL e/Cat. 4 in
accordance with EN ISO 13849-1 in the case of 3RM11/3RM13 fail-safe motor starters,
further relay contacts are installed in series with the semiconductors.

3.4 Device versions
The 3RM1 motor starters are characterized by their compact design and narrow width.
They can be used for easy assembly of fuseless load feeders with SIRIUS motor starter
protectors. Alternatively, combinations with fuses or other short-circuit protection devices are
possible.
This allows implementation of load feeders with coordination type 1 for short-circuit currents
of up to 55 kA at 400 V.
The 3RM1 motor starters are available in four different versions:

The 3RM1 motor starters are optionally available with screw connections or push-in
connections.
Push-in connections are a form of spring-loaded terminals allowing fast wiring without tools
for rigid conductors or conductors equipped with end sleeves. For wiring finely-stranded or
stranded conductors without end sleeves on push-in connections, a screwdriver (with
3.0 x 0.5 mm blade) is required. A screwdriver (with 3.0 x 0.5 mm blade) is also required to
disconnect a conductor.
The advantages of the push-in terminals are found, as with all spring-loaded terminals, in
speed of assembly and disassembly and vibration-proof connection. There is no need for the
checking and tightening required with screw connections.
