Residual hazards
Protection of
Disconnect the starttec before you start working on the device or opening it because the
l
persons
power connections L1, L2, L3, 1U, 1V, 1W, 2U, 2V, 2W, B1, B2 and BN carry dangerous
voltage:
– After you have opened the startec check whether the power connections L1, L2, L3, 1U,
1V, 1W, 2U, 2V, 2W, B1, B2 and BN are dead.
– Even if the starttec is inhibited (terminal 28 = LOW), the connections 1V, 2V, B1 and B2
carry dangerous voltage!
Shut down:
l
– External influences - e. g. overvoltage through lightning strike - may damage the starttec
with the consequence that the motor continues to run on two phases although the
starttec is inhibited (terminal 28 = LOW).
– If necessary, additional protective measures must be taken (e. g. extra separation of the
mains), dependent on the risk analysis of the machine/plant.
The metal housing of the starttec reaches an operating temperature of > 60 °C:
l
– Direct skin contact with the metal housing can lead to burns.
Device
Certain starttec settings can overheat the connected motor:
l
protection
– No PTC thermistor or thermostat (NC contact) connected to the motor and temperature
monitoring not configured (C0119).
– Rated motor current not adapted to motor (C0120).
2
– I t monitoring not active, no activation class set (C0121).
