Dangerous electrical 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, L3, DC+, DC-, BR, U/T1, V/T2, W/T3
power terminals.
The control signal terminals are isolated from the mains voltage.
There can be a dangerous voltage on the relay terminals (10, 11)
even if the variable frequency drive is not being supplied with
mains 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 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 P2-36).
