For simple applications TMS7 soft starters can be installed using
the three simple steps outlined below. For applications with
advanced control, protection or interface requirements a
comprehensive review of this Users Manual is recommended.
1. Installation & Connection
WARNING - ELECTRICAL SHOCK HAZARD
The TMS7 contains dangerous voltages when connected to
line voltage. Only a competent electrician should carry out
the electrical installation. Improper installation of the motor
or the TMS7 may cause equipment failure, serious injury or
death. Follow this manual and National Electrical Codes
(NEC®) and local safety codes.
1. Ensure the correct TMS7 model has been selected for the
connected motor and application type.
2. Mount the TMS7 making sure to allow adequate clearance
top and bottom for the free circulation of air through the
starter. (Refer to section 4.3 Mounting Instructions for further
detail.)
3. Connect the supply cables to starter input terminals L1, L2 &
L3.
4. Connect the motor cables to starter output terminals T1, T2
& T3.
5. Connect a control supply to starter input terminals A1 & A2
or A2 & A3. (Refer to section 6.2 Control Supply for further
detail).

4. Use the <UP> and/or <DOWN> keys adjust the FLC
setting to match the FLC of the connected motor.
5. Press the <STORE> key to store the new FLC setting.
6. Exit the programming mode by simultaneously pressing
then releasing the <FUNCTION> and <STORE> keys.
3. Operation
The TMS7 is now ready to control the motor. Motor operation
can be controlled using the <START> and <STOP> keys on the
TMS7 local control panel. Two other commonly used functions
that may be useful for basic installations are Function 2. Current Limit and Function 5. Stop Ramp Ti me. These functions can be
adjusted in the same manner as described above. (For a more
detailed description of the programming procedure refer to
section 7.1 Programming Procedure.)

2. Programming
Basic application requires only that the TMS7 be programmed
with the connected motor's nameplate full load current (FLC). To
program the TMS7 with the motor's FLC do the following:
1. Put the TMS7 into program mode by simultaneously
pressing then releasing the <FUNCTION> and <STORE>
keys.
2. Select Function 1. Motor Full Load Current by holding
down the <FUNCTION> key and then press the <UP> key
until the display shows "1".
3. Release the <FUNCTION> key to display the currently
stored value of Function 1. Motor Full Load Current.

CAUTION STATEMENTS
Caution Statements
WARNING - ELECTRICAL SHOCK
HAZARD
The TMS7 contains dangerous voltages when
connected to line voltage. Only a competent
electrician should carry out the electrical
installation. Improper installation of the motor
or the TMS7 may cause equipment failure,
serious injury or death. Follow this manual
and National Electrical Codes (NEC®) and
local safety codes.
GROUNDING AND BRANCH
CIRCUIT PROTECTION
It is the responsibility of the user or person
installing the TMS7 to provide proper
grounding and branch circuit protection
according to the National Electric Code
(NEC®) and local codes .
It is the installers responsibility to adhere to all instructions in
this manual, to follow good electrical practice and to seek advice
before operating this equipment in a manner other than as
detailed in this manual.
This symbol is used throughout this manual to
draw attention to topics of special importance
to the installation and operation of the TMS7
soft starter.
• Ensure that the TMS7 is completely isolated from the power
supply before attempting any work on the unit.
• Do not apply voltage to the control input terminals. These
are active 12/24VDC inputs and must be controlled with
potential free circuits.
• Ensure contacts/switches operating the control inputs are
suitable for low voltage, low current switching ie, gold flash
or similar.
• Ensure cables to the control inputs are segregated from AC
power and control wiring.
• Entry of metal swarf into the cabinet can cause equipment
failure.
• Do not connect Power Factor Correction capacitors to the
output of the TMS7. If static power factor correction is
employed, it must be connected to the supply side of the
TMS7.
• Before installing the TMS7 without a line contactor ensure
such connection meets local regulations and by-laws.
• If installing the TMS7 within a non-ventilated enclosure a
bypass contactor must be utilised to prevent excessive heat
build-up.
• If installing a by-pass contactor ensure phase connections
are correctly made
ie L1B-T1, L2B-T2, L3B-T3
• Removing control voltage resets the thermal model.
The examples and diagrams in this manual are included solely for illustrative
purposes. Users are cautioned that 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 or indirect or consequential
damages resulting from the use or application of this equipment.

This product has been designed for class A equipment. Use of
the product in domestic environments may cause radio
interference, in which case the user may be required to employ
additional mitigation methods.
Standards Approvals

To adjust the bus bar configuration first remove the TMS7 cover
and main control module. Next loosen and remove the bus bar
fixing bolts. The bus bars can then be removed and reinstalled
into the starter in the desired configuration. The fixing bolts
should then be refitted and tightened to a torque of 8.5NM.
When re-orienting bus bars L1, L2, L3 the current transformers
must also be relocated.
Care must be taken to ensure that foreign matter does not
contaminate the jointing compound and become trapped
between the bus bar and its mounting plate. If the paste does
become contaminated, clean and replace with a jointing
compound suitable for aluminium to aluminium, or aluminium to
copper joints.
4.3 Mounting Instructions
Models TMS7-4007 ~ 4132 can be wall mounted or installed
inside another enclosure. These models can be mounted side
by side with no clearance but a 100mm allowance must be
made top and bottom for air intake and exhaust.
The bus bars on models TMS7-4150 ~ TMS7-4800 can be
adjusted to provide four different input/output power terminal
configurations.
Models TMS7-4150 ~ 4800 have an IP00 rating and must be
mounted in another enclosure. These models can be mounted
side by side with no clearance but a 200mm allowance must be
made top and bottom for air intake and exhaust.

INSTALLATION
4.4 Ventilation
When installing TMS7 starters in an enclosure there must be
sufficient air flow through the enclosure to limit heat rise within
the enclosure. Temperature within the enclosure must be kept
at, or below, the TMS7 maximum ambient temperature rating.
If installing an TMS7 within a totally sealed enclosure a bypass
contactor must be employed to eliminate heat dissipation from
the soft starter during run.
Soft starters dissipate approximately 4.5 watts per amp. The
table below shows air flow requirements for selected motor
currents. If other heat sources are installed in an enclosure
along with the TMS7 an additional air flow allowance must be
made for these items. Note that heat generation from
semiconductor fuses, if used, can be eliminated by installing
these within the bypass loop.
