4.2 Hazard warnings for operation
Please observe the following notes.
DANGER
Commissioning is only to be completed by qualified technicians.
DANGER
Hazardous voltage!
The safety instructions on pages I and II must be followed.
DANGER
The components in the DE1 variable speed starter's power
section will remain energized as long as the supply voltage
(mains voltage) is connected. This includes, for example, power
terminals L1/L, L2/N, L3, U, V, and W.
The control signal terminals are isolated from the line power
potential.
There might be a dangerous voltage at the relay terminals
(13, 14) even if the variable speed starter is not being powered
with mains voltage (when the relay contacts are connected to
PLCs with voltages > 48 VAC / 60 VDC, for example).
DANGER
The components in the DE1 variable speed starter's power
section will remain energized for up to 5 minutes after the
supply voltage is switched off (due to the DC link capacitors'
discharge time).
Pay attention to hazard warnings!
DANGER
Following a shutdown (fault, mains voltage off), the motor
can start automatically (when the supply voltage is switched
back on) if the automatic restart function has been enabled
(

parameters P-31).
