WARNING
Hazardous voltage can cause electric shock and burns.
To avoid shock hazard, disconnect all power to the
controller, motor or other control devices before any
work is performed on this equipment. Failure to do so
will result in personal injury, death or substantial
property damage.
Do not apply a disconnect device on the output of the
S611 soft starter unless a means to turn off the soft
starter when disconnect switch is open is used. Opening
disconnect while the soft starter is operating may cause
a malfunction. Closing disconnect switch while the soft
starter is operating will result in a soft starter failure and
potential equipment damage and personnel hazard.
Note: Short circuit protection must be applied on the line
side of the soft starter.
Do not attempt to lift the soft starter by the cover
only.
Lug Installation
Install the lugs below the bus bar to assure anti-rotation.
Refer to figure “Lug and Bolt Torque Support” on this page.
Power Wiring Diagram
Lug Bolt Torque Support
Note: When securing the lugs onto the bus bars of the soft
starters, use a suitable tool such as another wrench to
counteract the bolt torque and prevent excessive side
loads being placed on the supports. Refer to figure “Lug
and Bolt Torque Support” above.
Remove the tie wraps for CTs on Frames C, D, E, and
F. Move each CT to the load cables during assembly
as shown in the figure “CT Location” on
Page 2 . Each
CT should be properly supported with tie wraps
ensuring that the CT is not supported by the leads.
Properly secure CT leads.
When securing the Current Transformers (CTs) onto
the T1, T2, and T3 bus bars of the soft starter, correct
orientation of the CT must be observed to ensure
proper operation of the soft starter. Each CT is marked
with a symbol “IX” adjacent to the leads. This symbol
shown in the figure “CT Polarity Identification” on
Page 2 indicates the line side (or voltage source side)
of the device.
