Relocating the Internal Current
Transformers for 6 wire operation.
The SS6000 comes standard with internal Current
Transformers (C.T’s) for monitoring the current
during acceleration, deceleration and when in
bypass.
It is important that the SS6000 be wired in a
manner to ensure the C.T’s are always monitoring
the motor current. For this reason 9 terminals are
provided. This is important to ensure continual
protection of the soft starter, the motor and the
load. The correct installation of the C.T’s is crucial
for optimum performance of the SS6000 torque
control system. In some situations such as 6 wire
operation, it may be necessary to relocate the
C.T’s external to the SS6000. For 6 wire operation
the C.T’s are to be installed on the incoming line
supply cables so that the line current is monitored
(not the phase currents).
The SS6000 can be purchased with C.T’s external
by ordering ‘ prepared for 6 wire’;
Part no.

Installation of external C.T’s
When relocating the C.T’s external to the soft
starter it is important to ensure the following:
1. C.T’s are installed on L1 & L3
2. C.T’s are installed in correct direction
P1 label = line side
3. C.T’s are terminated with correct phasing.
S1 = Red
S2 = Black
The C.T’s supplied with the SS6000 has a label
which shows the correct phase and direction.
If the C.T’s are not installed correctly the SS6000
will display a fault or a ‘C.T Phase error’.
Check for correct installation
If a CT phase error occurs the problem may be
identify under the menu ‘Starter Diagnosis’. ‘+L1 /
+L3’ should be displayed.
> If L2 is displayed move the CT from L2 phase.
> If a “-“ is displayed, the direction of the
corresponding CT needs to be reversed.
