As a rule, the Altistart 48 control (CL1 - CL2) and power (1/L1 - 3/L2 - 5/L3) supplies must be
disconnected before any operation on either the electrical or mechanical parts of the
installation or machine.
During operation the motor can be stopped by cancelling the run command. The starter
remains powered up. If personnel safety requires prevention of sudden restarts, this electronic
locking system is not sufficient: fit a breaker on the power circuit.
The starter is fitted with safety devices which, in the event of a fault, can stop the starter and
ENGLISH
consequently the motor. The motor itself may be stopped by a mechanical blockage. Finally,
voltage variations or line supply failures can also cause shutdowns.
If the cause of the shutdown disappears, there is a risk of restarting which may endanger
certain machines or installations, especially those which must conform to safety regulations.
In this case the user must take precautions against the possibility of restarts, in particular by
using a low speed detector to cut off power to the starter if the motor performs an
unprogrammed shutdown.
The products and equipment described in this document may be changed or modified at any
time, either from a technical point of view or in the way they are operated. Their description can
in no way be considered contractual.
This starter must be installed and set up in accordance with both international and national
standards. Bringing the device into conformity is the responsibility of the systems integrator
who must observe the EMC directive among others within the European Union.
The specifications contained in this document must be applied in order to comply with the
essential requirements of the EMC directive.
The Altistart 48 must be considered as a component: it is neither a machine nor a device ready
for use in accordance with European directives (machinery directive and electromagnetic
compatibility directive). It is the responsibility of the final integrator to guarantee conformity to
the relevant standards.

• The power line supply (1/L1 - 3/L2 - 5/L3), ensuring that it is off
• The motor (2/T1 - 4/T2 - 6/T3), ensuring that its coupling corresponds to the supply voltage
Note
: If a bypass contactor is used, connect it to L1 L2 L3 on the line supply side and to terminals A2 B2 C2
provided for this purpose on the Altistart 48. See the diagrams on page 112.
If the ATS48•••Q is used in the motor delta windings, follow the recommendations on page 92, page 93 and
the diagrams on page 113.

Preliminary recommendations
Handling and storage
To ensure the starter is protected before installation, handle and store the device in its packaging.
Handling on installation
The Altistart 48 range comprises 6 sizes of device, with various weights and dimensions.
Small starters can be removed from their packaging and installed without a handling device.
A handling device must be used with large starters; for this reason they are supplied with handling "lugs". The
precautions described below must be observed:
ENGLISH
Do not handle the starter by the power rails

Operating recommendations
Available torque
Curves Ts and Is represent the direct line starting of an
asynchronous motor.
Curve Ta1 indicates the total torque range available with an
ATS 48, which is dependent on the limiting current ILt. The
progression of the starter is controlled by the motor torque within
this range.
Tr: Resistive torque, which must always be less than the Ts1
torque.
Selecting the soft start - soft stop unit
S1 motor duty corresponds to starting followed by operation at constant load enabling the thermal equilibrium
to be reached.
S4 motor duty corresponds to a cycle comprising starting, operation at constant load and an idle period. This
cycle is characterised by a load factor.
The Altistart 48 must be selected depending on the type of application ("standard" or "severe") and the nominal
power of the motor. "Standard" or "severe" applications define the limiting values of the current and the cycle
for motor duties S1 and S4.
Caution: Do not use the Altistart 48 upstream of loads other than motors (for example
transformers and resistors are forbidden). Do not connect power factor correction
capacitors to the terminals of a motor controlled by an Altistart 48
ENGLISH
Standard application
Example: centrifugal pump
In standard applications, the Altistart 48 is designed to provide:
• in S1 duty: starting at 4 In for 23 seconds or starting at 3 In for 46 seconds from a cold state.
• in S4 duty: a load factor of 50% and 10 starts per hour, with 3 In for 23 seconds or 4 In for 12 seconds or an
equivalent thermal cycle.
In this case, the motor thermal protection must conform to protection class 10.
Severe application
Example: grinder
In severe applications, the Altistart 48 is designed for S4 duty with a load factor of 50% and 5 starts per hour
at 4 In for 23 seconds or an equivalent thermal cycle.
In this case, the motor thermal protection must conform to protection class 20. Current

Note
: The starter can be oversized by one rating, for example by selecting an ATS 48D17Q for an 11 kW 400 V motor in motor duty S4.
To do this, short-circuit the Altistart at the end of starting. This permits 10 starts per hour at 3 times In for
23 seconds maximum or equivalent and the thermal motor protection must conform to class 10.

Operating recommendations
The Altistart 48 connected in the motor delta winding in series with each
winding
ATS48•••Q starters connected to motors with delta connections can be inserted in series in the motor windings.
They are powered by a current which is less than the line current by a factor of √3, which enables a starter with
a lower rating to be used.
This option can be configured in the Advanced settings menu (dLt = On).
The nominal current and limiting current settings as well as the current displayed during operation are on-line
values and so do not have to be calculated by the user.
The Altistart 48 can only be connected in the motor delta winding for ATS48•••Q starters. This
means that:
- only freewheel stopping is possible
- cascading is not possible
- preheating is not possible
See the tables on page 94 for more information about starter-motor combinations.
Connection in the motor delta
winding
ENGLISH
Example:
A 400 V - 110 kW motor with a line current of 195 A (nominal current for the delta connection).
The current in each winding is equal to 195/1.7 or 114 A.
The rating is determined by selecting the starter with a maximum permanent nominal current just above this
current, i.e. 140 A (ATS48C14Q for a standard application).
To avoid having to calculate the rating in this way, use the tables on page 96 and 97 which indicate the rating
of the starter corresponding to the motor power for each application type.
