CAUTION:
Input power terminals
– Although the leakage current of one single CONTACTRON Speed Starter is
10 mA AC, electric shock may still occur due to the leakage current from other
equipment such as motors and leads. Therefore, it is recommended that you install
one of the followings to prevent danger caused by electric shock.
– Use a copper wire with a cross-section of 10 mm
2
or connect 2x PE with at least
outer conductor cross section.
– Install an Earth Leakage Circuit Breaker (ELCB) or a residual current device
(RCD).
– Due to the high frequency current of the leakage current of the CONTACTRON Speed
Starter, select a Type B ELCB or RCD specifically for the CONTACTRON Speed
Starter when using an ELCB. The power system of the CONTACTRON Speed Starter
affects the power factor, so select a Molded Case Circuit Breaker (MCCB) with larger
capacity.
– Use shielded wire or conduit for the power wiring and ground the two ends of the
shielding or conduit.
– Do not run and stop the CONTACTRON Speed Starters by turning the power ON and
OFF. Run and stop the CONTACTRON Speed Starters by sending the RUN and
STOP commands to the control terminals. If you still need to run and stop the
CONTACTRON Speed Starters by turning the power ON and OFF, do so no more
often than once per hour.
– To comply with UL standards, connect the CONTACTRON Speed Starter to a three-
phase three-wire or three-phase four-wire Wye system type of mains power system.
– For use in the IT-system, refer to “IT jumper” on page 38 .
Output terminals of the main circuit
– Use well-insulated motors to prevent any electric leakage from motors.
– When the CONTACTRON Speed Starter output terminals U, V, and W are connected
to the motor terminals U, V, and W respectively, the "R" LED indicator on the digital
control panel is ON. This means the CONTACTRON Speed Starter executes running
forward, and the motor rotates clockwise (viewed from the shaft end of the motor).
– On the contrary, when the "L" LED indicator lights, the CONTACTRON Speed Starter
executes running in reverse, and the motor rotates as shown in Figure 1-1 . If the
CONTACTRON Speed Starter executes running forward but the motor rotates in a
reverse direction, exchange any two of the U, V and W motor leads.
