2 – 90
Warning
The maximum cable length between the SM 1xx and the inverter is 1 m.
Select the cross section of the grounding conductor (yellow/green) at the
voltage protection module so that the cross section of the grounding
conductor is not less than half the cross section of the leads to the SM 1xx
(e. g. leads = 40 mm
However, a cross section of at least 10 mm
conductor.
Warning
Due to the high power, the SM 130 features a temperature switch. The
switch must be evaluated in the EMERGENCY STOP chain. The switch
opens at temperatures above 60 °C. This makes it possible to prevent a
subsequent switch-on temporarily.
Warning
With the SM 130, the three motor phases are connected to three screws
located in the housing of the SM 130. Use only insulated terminals for the
connection. The tightening torque for the screws is approximately 9 Nm.
