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 iv and v must be followed.
DANGER
The components in the adjustable frequency drive’s power section
are energized if the supply voltage (line voltage) is connected. For
instance: power terminals L1, L2/N, L3, R+, R–, U/T1, V/T2, W/T3.
The control signal terminals are isolated from the line power
potential.
There can be a dangerous voltage on the relay terminals (22 to 26)
even if the frequency converter is not being supplied with line
voltage (e.g., integration of relay contacts in control systems with
230 Vac)
DANGER
The components in the frequency converter'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, line voltage off), the motor can start
automatically (when the supply voltage is switched back on) if the
automatic restart function has been enabled.
