5.4 Operational hazard warnings
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 variable frequency drive’s power section
are energized if the supply voltage (mains voltage) is connected.
For instance: L1/L, L2/N, DC+, DC-, BR, U/T1, V/T2 power
terminals.
The control signal terminals are isolated from the line power
potential.
There can be a dangerous voltage on the relay terminals (10, 11)
even if the variable frequency drive is not being supplied with
line voltage (e.g., integration of relay contacts in control systems
with voltage > 48 V AC / 60 V DC).
DANGER
The components in the variable frequency drive’s power section
remain energized up to five (5) minutes after the supply voltage
has been switched off (intermediate circuit capacitor
discharging 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).
