1 Safety Information
WARNING
Indicates a hazard that may cause personal injury or death.
CAUTION
Indicates a hazard that may damage the equipment or installation.
NOTE
Provides helpful information.
1.1 Electrical safety - general warning
The voltages used in the starter can cause severe electrical shock and/or burns, and could be lethal.
Extreme care is necessary at all times when working with or adjacent to the starter.
Specific warnings are given at the relevant places in this guide.
1.2 System Design and Safety of Personnel
The starter is intended as a component for professional incorporation into complete equipment or a
system. If installed incorrectly, the starter may present a safety hazard.
The starter uses high voltages and currents, carries stored electrical energy, and is used to control
equipment which can cause injury.
Close attention is required to the electrical installation and the system design to avoid hazards either in
normal operation or in the event of equipment malfunction. System design, installation, commissioning
and maintenance must be carried out by personnel who have the necessary training and experience.
They must read this safety information and this guide carefully.
None of the starter functions must be used to ensure safety of personnel, ie they must not be
used for safety-related functions.
Careful consideration must be given to the functions of the starter which might result in a hazard, either
through their intended behaviour or through incorrect operation due to a fault. In any application where a
malfunction of the starter or its control system could lead to or allow damage, loss or injury, a risk analysis
must be carried out, and where necessary, further measures taken to reduce the risk.
The system designer is responsible for ensuring that the complete system is safe and designed correctly
according to the relevant safety standards.
1.3 Environmental limits
Instructions regarding transport, storage, installation and use of the starter must be complied with,
including the specified environmental limits. Starters must not be subjected to excessive physical force.
1.4 Compliance with regulations
The installer is responsible for complying with all relevant regulations, such as national wiring regulations,
accident prevention regulations and electromagnetic compatibility (EMC) regulations. Particular attention
must be given to the cross-sectional areas of conductors, the selection of fuses or other protection, and
protective ground connections.
Within the European Union, all machinery in which this product is used must comply with the following
directives:
2006/42/EC: Safety of machinery.
2014/30/EU: Electromagnetic Compatibility.
1.5 Motor
Ensure the motor is installed in accordance with the manufacturer’s recommendations. Ensure the motor
shaft is not exposed.
1.6 Adjusting parameters
Some parameters have a profound effect on the operation of the starter. They must not be altered without
careful consideration of the impact on the controlled system. Measures must be taken to prevent
unwanted changes due to error or tampering.

Issue: F
1.7 Electrical Installation
1.7.1 Electrical shock risk
The voltages present in the following locations can cause severe electric shock and may be lethal:
• AC supply cables and connections
• Output cables and connections
• Many internal parts of the starter, and external option units
The AC supply must be disconnected from the starter using an approved isolation device before any
cover is removed from the starter or before any servicing work is performed.
1.7.2 Power-up procedure
WARNING
Always apply control voltage before (or with) mains voltage.
After transportation, mechanical shock or rough handling there is a possibility that the bypass contactor
may have latched into the on state. To prevent the possibility of the motor starting immediately, on first
commissioning or operation after transportation, always ensure that the control supply is applied before
the power, so that the contactor state is initialised.
1.7.3 STOP function
The STOP function does not remove dangerous voltages from the starter, the motor or any external
option units.
1.7.4 Equipment supplied by plug and socket
The control supply terminals of the starter are connected to the internal capacitors through rectifier diodes
which are not intended to give safety isolation. If the plug terminals can be touched when the plug is
disconnected from the socket, a means of automatically isolating the plug from the starter must be used
(e.g. a latching relay).
1.7.5 Short circuit
The Digistart D2 is not short circuit proof. After severe overload or short circuit, the operation of the
Digistart D2 should be fully tested by an authorised service agent.

For sizing of the control fuse, see Technical Data on page 18.
The maximum cable run is determined by the type of cable used, provided the maximum resistance of
this cable does not exceed 100 Ohms. The cables must be twisted in pairs and shielded. The shield must
be grounded at one end only, that is, at the soft starter end. To avoid any EMC disturbance from the
motor power cables, the thermistor cable must be separated from the motor power cables by a minimum
parallel distance of 300 mm.
4.1.3 Motor Thermistor
Motor thermistors can be connected directly to the Digistart D2 terminals TH1, TH2. If motor thermistors
are not used, there must be a link between TH1, TH2 (the Digistart D2 is supplied with a link fitted).

4.1.4 Outputs
Main Contactor Output
The Main Contactor output (terminals COM2, RLO2) closes as soon as the soft starter receives a start
command and remains closed while the soft starter is controlling the motor (until the motor starts a coast
to stop, or until the end of a soft stop). The Main Contactor output will also open if the soft starter trips.
The Main Contactor output can be used to directly control a main contactor coil.
Programmable Output
The programmable output relay (terminals COM1, RLO1) can be used to signal either trip or run status.
This relay is normally open.
Trip:
The relay closes when the Digistart D2 trips. The relay can be used to operate the shunt-trip mechanism
of an upstream circuit breaker (in order to isolate the motor branch circuit), or to signal the trip to an
automation system or externally. The relay will open when the trip is reset.
Run:
The relay operates when the soft start is complete, the bypass relays are closed and full voltage is being
applied to the motor. The relay can be used to operate a contactor for power factor correction capacitors,
or to signal soft starter run status to an automation system.
4.1.5 Semiconductor Fuses
Semiconductor fuses can be used with Digistart D2 soft starters to reduce the potential for damage to
SCRs from transient overload currents and for Type 2 coordination. Digistart D2 soft starters have been
tested to achieve Type 2 coordination with semiconductor fuses. Suitable Bussmann and Ferraz/Mersen
semiconductor fuses are detailed below.

6.3 Reset
Trips can be cleared by pressing the Reset button on the soft starter, sending a Reset command from the
serial communications network, or by switching the control inputs.
To clear a trip via the control inputs, the soft starter requires a closed to open transition on the stop input (DI2).
• In three-wire control, use the external stop button to momentarily open the stop input (open
CSL-DI2).
• In two-wire control, if the soft starter tripped with a start signal present, remove the start signal
The Reset button is located on the front of the unit, above the adjustment switches.
The soft starter will trip again immediately if the cause of the trip still exists.
(open CSL to DI1, DI2).
• In two wire control, if the Digistart D2 tripped with no start signal present (eg Digistart D2 motor
thermistor trip), apply then remove the start signal (close then reopen CSL to DI1, DI2).

6.4 Protections
The Digistart D2 includes the following types of protection for the motor and starter:
6.4.1 Excess Start Time Protection
The Digistart D2 will trip on excess start time if the motor does not successfully start within the time
selected in the Excess Start Time setting. This may indicate that the load has stalled.
If the soft starter frequently trips on excess start time:
• check that the Current Limit setting is high enough for the application
• check that the Excess Start Time setting is long enough for the application
• check that the load has not stalled or increased since the soft starter was installed
6.4.2 Motor Overload Protection
The Digistart D2 will trip on motor overload if it calculates that the motor has been running above its
operating range for longer than the time selected in the Motor Trip Class setting. Motor Trip Class should
be set to match the motor's locked rotor time. If this information is not available from the motor datasheet,
use the default setting (Motor Trip Class = 10). Using a higher setting can damage the motor.
NOTE
Motor overload protection does not protect the soft starter, and does not protect the motor from
short circuit.
6.4.3 Current Imbalance Protection
The Digistart D2 will trip on current imbalance if the highest and lowest currents on the three phases vary
by an average of 30% for more than 3 seconds. Current imbalance protection is not adjustable, and is
only active when the average motor current is 50% or more of the programmed motor FLC.
If the soft starter frequently trips on current imbalance:
6.4.4 Supply Frequency Protection
The soft starter will trip on supply frequency if the frequency rises above 72 Hz or falls below 40 Hz for
more than five seconds while the soft starter is running. These trip points are not adjustable.
In pre-start, starting and stopping modes the high and low frequency limits both apply with no time delay.
A supply frequency trip will also occur if:
6.4.5 Bypass Overload Protection
Bypass overload protection protects the soft starter from severe operating overloads while running. The
protection is not adjustable and has two components:
If the trip occurs frequently, this indicates that the soft starter has not been selected correctly for the
application.
• check that there is no imbalance on the mains voltage (on the input side of the soft starter)
• insulation test the motor
• move all input cables over one position (move L1 cable to L2, move L2 cable to L3, move L3
cable to L1) to rule out a cabling fault
• all three input phases are lost while the soft starter is running
• all three input phases fall below 120 VAC at start or while the soft starter is running
• the line contactor opens while running
• The soft starter will trip if it detects overcurrent at 600% of the programmed motor full load
current.
• The soft starter models the temperature of the internal bypass relays and will trip if the
temperature exceeds the safe operating level.
