Safety
ImporTanT InformaTIon
Installers should read and understand the instructions in this guide prior to
installing, operating and maintaining the soft start. The following symbols may
appear in this guide or on the soft start to warn of potential hazards or to draw
attention to certain information.
CauTIon sTaTemenTs
The examples and diagrams in this manual are included solely for illustrative
purposes. The information contained in this manual is subject to change at any time
and without prior notice. In no event will responsibility or liability be accepted for
direct, indirect or consequential damages resulting from the use or application of
this equipment.

• SR35 soft starters contain dangerous
voltages when connected to the mains
supply. Only qualified personnel that have
been completely trained and authorized,
should carry out installation, operation and
maintenance of this equipment.
• Installation of the soft start must be made in
accordance with existing local and national
electrical codes and regulations and have a
minimum protection rating.
• It is the responsibility of the installer to
provide suitable grounding and branch
circuit protection in accordance with local
electrical safety codes.
• This soft starter contains no serviceable or
re-usable parts.
• The STOP function of the soft starter does
not isolate dangerous voltages from the
output of the soft start. An approved
electrical isolation device must be used
to disconnect the soft start from the
incoming supply before accessing electrical
connections.

Mechanical Installation
mounTIng
Fix the unit to a flat, vertical surface using the mounting holes (or slots) on its
base-plate. The mechanical outline diagrams, shown on page 6, give the
dimensions and mounting hole positions for each model. Ensure that:
• The orientation of the unit has the ‘TOP’ uppermost.
• The location allows adequate front access.
• You can view the keypad display.
• Do not install other equipment that generates significant heat close to the soft
starter.
requIremenTs for an enClosure
For a typical industrial environment, an enclosure would provide the following:
• A single location for the unit and its protection/isolation switch-gear
• The safe termination of cabling and/or busbars
• Means to effect proper air flow through the enclosure if the heat output of the unit is
greater than the cabinet can dissipate
enClosure VenTIlaTIon
When installing the SR35 soft starter into a cabinet, ventilation must be provided
if the heat output of the unit is greater than the cabinet can dissipate. The heat
dissipated can be approximated with the formula:
• Starting: Watts (SR35) =
(start current(A)) x (start time(s)) x (number of starts per hour) ÷ 1800
• Running: Watts (SR35) = 0.4 x running amps
Use the following formula to determine the fan requirement. An allowance has been
incorporated into the formula so that the figure for Q is the air delivery in the fan
suppliers’ data.
• Q = (4 x Wt) ÷ (Tmax - Tamb)
• Q = Volume of air (cubic meters per hour - m3/h)
• Wt=
Heat produced by the unit and all other heat sources within the enclosure (Watts)
• Tmax = Maximum permissible temperature within the enclosure
(40°C for a fully rated SR35)
• Tamb = Temperature of the air entering the enclosure (°C)
(If you prefer to work in CFM, substitute °F for °C. Q is now in CFM)
alTITude deraTe
Altitude above sea level 1000m (3281ft).
Above 1000m, derate by 1% of SR35 i.e. per 100m (328ft) to a maximum altitude of
2000m (6562ft).
ambIenT TemperaTure deraTe
-20°C (-4°F) to 40°C (104°F).
Above 40°C, derate linearly by 2% of SR35 i.e. per °C to a maximum of 60°C (140°F).

SR35 Quick-Start Guide
Stellar® SR35 Series Soft Starter Quick Start Guide – 1st Ed – 07/09/2020 5
HandlIng
The SR35 soft start range is comprised of three frame sizes of various weights and
dimensions. See “Dimensions” on page 6 for further information.
Prior to installing the SR35 unit, the installer should carry out a risk assessment. If
considered appropriate, a suitable handling device should be used.
Do not lift the SR35 unit by attachment to the 3-phase terminal connections or
busbars.
warnIng: hanDlIng anD lIftIng hazarD
ensure the area below any equIpment Is clear of all personnel anD property. faIlure
to follow thIs practIce may result In Death, serIous Injury, or Damage to equIpment.
aCCessorIes
The following accessories have been developed and tested for use with the SR35
range of soft starters:
• SR35-KPD-REM Remote Keypad for SR35-017 to SR35-361. Provides remote
functionality for up to 32 soft starter units.
• SR35-PSU 100VAC – 240VAC power supply. Provides mains voltage control power
and digital control functionality. For use with SR35-017 to SR35-361.
• SR35-FAN-1 Cooling fan accessory for SR35-017 to SR35-065 only. Increases the
number of starts per hour (see “Fan Option” on page 20).
• SR35-FAN-2 Cooling fan accessory for SR35-077 to SR35-192 only. Increases the
number of starts per hour (see “Fan Option” on page 20).

Motor Overload
The SR35 provides full motor overload protection, configurable through the user
interface. Overload trip settings are determined by the Motor Current setting and the
Trip Class setting. Trip class choices are Class 10, Class 20, and Class 30. The SR35
soft starters are protected using full I2T motor overload with memory.
Please note: When the overload has tripped, there is a forced cooling time to
allow the overload to recover before the next start.
The ‘warm’ trip times are 50% of the ‘cold’ trip time.
