KFU 2- (up to 3.0 kW) and 401 (up to 4.0 kW)
The mains connection of the frequency inverter is via plug-in terminal
X1
. The connec-
tion of motor and brake resistor to the frequency inverter is done via plug-in terminal
X2. Degree of protection IP20 (EN60529) is only guaranteed with the terminals
plugged.
Danger!
Switch off power supply
before connecting or disconnecting the keyed
plug-in terminals
X1
and
X2.
Dangerous voltage may be present at the
mains terminals and the DC terminals even after the frequency inverter
has been disconnected safely from power supply. Wait for some minutes
until the DC link capacitors have discharged before starting the work.
The unit may only be connected with the power supply switched off.
Make sure that the frequency inverter is discharged.
