1.3 Field of application of the product
1.3.1 Intended use
The CONTACTRON Speed Starter is a motor switching device to start, reverse and protect
the asynchronous motor in case of an overload and switch off the motor in case of an
emergency stop (STO). Additionally, a ramp for soft start/soft stop as well as different
speeds can be set in the device. This device is only suitable for control cabinets.
1.3.2 Foreseeable misuse
– When operating a 1-phase device with 1-phase mains with at least 200 V AC, you must
not set the motor voltage to 110 V AC in the OPTIONS menu. Otherwise, the device
could be damaged.
– Do not connect a 1-phase device to three phases.
– Do not unmount the control panel while the device is connected to power.
1.3.3 Product changes
Changes or modifications to hardware and software of the device are not permitted.
– Incorrect operation or modifications to the device can endanger your safety or damage
the device. Do not repair the device yourself. If the device is defective, please contact
Phoenix Contact.
1.3.4 After unpacking
After receiving the CONTACTRON Speed Starter, check the following:
– Inspect the unit after unpacking to ensure that it was not damaged during shipment.
Make sure that the part number printed on the package matches the part number
indicated on the nameplate.
– Make sure that the mains voltage is within the range indicated on the nameplate. Install
the CONTACTRON Speed Starter according to the instructions in this manual.
– Before applying power, make sure that all connections, for example mains voltage, the
control wiring and the motor cables are connected correctly.
– When wiring the CONTACTRON Speed Starter, make sure that the wiring of input
terminals "L1, L2, L3" and output terminals "U, V, W" are correct to prevent damage to
the CONTACTRON Speed Starter.

For your safety
109908_en_00 PHOENIX CONTACT 11 / 146
1.4 Safety notes
– Installation, operation, and maintenance may only be carried out by qualified
electricians. Follow the installation instructions as described.
– When installing and operating the device, observe the applicable regulations and
safety directives (including national safety directives), as well as general technical
regulations.
– Install the device in accordance with the instructions described in the installation notes.
Accessing circuits within the device is prohibited.
– Only clean the device with a suitable damp cloth. Do not use abrasive cleaners or
aggressive solvents. Switch off the device before cleaning and disconnect the device
from the power distribution.
– Ensure that all devices and adapters are attached and connected correctly to prevent
the devices from being damaged.
– Refer to the documentation before installation.
The "attention symbol" on the device label means:
Read the safety and installation notes in their entirety.
Failure to follow the instructions may impair the safety features provided.
The "high voltage symbol" on the device label means: Dangerous contact voltage
Only qualified personnel may do this work. The personnel must be familiar with the
necessary safety precautions.
Failure to follow the instructions may result in damage or injury.
The "hot surfaces symbol" on the device label means:
The surfaces of the device may get hot.
Use personal protective equipment or wait for cooling-off.
Failure to follow the instructions may result in damage or injury.

DANGER:
– Turn off the CONTACTRON Speed Starter power before doing any wiring. A charge
with hazardous voltages may remain in the DC link circuit capacitors even after the
power has been turned off for a short time. For your safety, do not start wiring before
the voltage drops to a safe level (less than 25 V DC). Installing wiring with a residual
voltage may cause personal injury, sparks and a short circuit.
– Make sure that power is only applied to the L1, L2, and L3 terminals. Failure to comply
may result in damage to the equipment. The voltage and current must be in the range
indicated on the nameplate (refer to 2.2 “Nameplate information (example)” for
details).
– All units must be grounded directly to a common ground terminal to prevent damage
from an electric arc or electric shock and reduce noise interference.
CAUTION:
– For your safety, choose wires that comply with local regulations when wiring.
– Check the following items after finishing the wiring:
– Are all connections correct?
– Are there any loose wires?
– Are there any short circuits between the terminals or to ground?
DANGER:
– If necessary, only use an inductive filter at the motor output terminals U, V, W of the
CONTACTRON Speed Starter. Do not use phase-compensation capacitors or I-C
(Inductance-Capacitance) or R-C (Resistance-Capacitance).
– Do not connect surge absorbers at the output terminals of CONTACTRON Speed
Starters.
– Ensure proper insulation of the main circuit wiring in accordance with the relevant
safety regulations.

CAUTION:
Input power terminals
– Although the leakage current of one single CONTACTRON Speed Starter is
10 mA AC, electric shock may still occur due to the leakage current from other
equipment such as motors and leads. Therefore, it is recommended that you install
one of the followings to prevent danger caused by electric shock.
– Use a copper wire with a cross-section of 10 mm2or connect 2x PE with at least
outer conductor cross section.
– Install an Earth Leakage Circuit Breaker (ELCB) or a residual current device
(RCD).
– Due to the high frequency current of the leakage current of the CONTACTRON Speed
Starter, select a Type B ELCB or RCD specifically for the CONTACTRON Speed
Starter when using an ELCB. The power system of the CONTACTRON Speed Starter
affects the power factor, so select a Molded Case Circuit Breaker (MCCB) with larger
capacity.
– Use shielded wire or conduit for the power wiring and ground the two ends of the
shielding or conduit.
– Do not run and stop the CONTACTRON Speed Starters by turning the power ON and
OFF. Run and stop the CONTACTRON Speed Starters by sending the RUN and
STOP commands to the control terminals. If you still need to run and stop the
CONTACTRON Speed Starters by turning the power ON and OFF, do so no more
often than once per hour.
– To comply with UL standards, connect the CONTACTRON Speed Starter to a three-
phase three-wire or three-phase four-wire Wye system type of mains power system.
– For use in the IT-system, refer to “IT jumper” on page 38.
Output terminals of the main circuit
– Use well-insulated motors to prevent any electric leakage from motors.
– When the CONTACTRON Speed Starter output terminals U, V, and W are connected
to the motor terminals U, V, and W respectively, the "R" LED indicator on the digital
control panel is ON. This means the CONTACTRON Speed Starter executes running
forward, and the motor rotates clockwise (viewed from the shaft end of the motor).
– On the contrary, when the "L" LED indicator lights, the CONTACTRON Speed Starter
executes running in reverse, and the motor rotates as shown in Figure 1-1. If the
CONTACTRON Speed Starter executes running forward but the motor rotates in a
reverse direction, exchange any two of the U, V and W motor leads.
