3RW44 Soft starter
Safety Instructions
DANGER
!
Hazardous voltage.
Will cause death or serious injury.
Disconnect power before working on equipment.
DANGER
!
Hazardous voltage.
Will cause death or serious injury.
To avoid electrical shock or burns, do not touch motor
control device terminals when voltage is applied to the
device. Output terminals will have voltage present even
when motor control device is OFF.
NOTICE
Can cause property damage.
If dc braking is selected with inside delta mode, natural slowdown
mode will occur.
NOTICE
Set the rated operating current Ie of the connected drive in order to
ensure the correct functioning of the soft starter when starting and
stopping as well as to protect the motor. The rated operating current
Ie can be read off the motor rating plate, in relation to the relevant
line voltage.
This setting is irrespective of the connection method of the soft
starter (soft starter in standard or inside delta circuit). The settable
current limitation value (in %) always refers to the set rated operat-
ing current Ie of the motor.
Phase currents shown on the display are always the line currents
(also in inside delta circuit) and not the currents in the motor
windings.
WARNING
!
Danger of severe personal injury.
To save changed parameters permanently (even in the case of
control supply voltage failure), the settings must be saved via the
menu item "Settings - Saving options".
DANGER
!
Hazardous voltage.
Will cause death or serious injury.
The non-assigned (unlabeled) terminals of the 3RW44
must not be used.
CAUTION
!
Taking environmental conditions into account, the devices must be
installed in control cabinets of IP54 degree of protection (pollution
degree 2).

NOTE
The 3RW44 soft starter fulfills degree of noise suppression A.
NOTICE
Power-factor-correcting (PFC) Capacitors.
Do not use PFC capacitors at the motor control device
output terminals. Connection to the output terminals will
damage the motor control device. If capacitors for reac-
tive power compensation are used, they must be con-
nected on the line side of the device.
When an isolation contactor is used with the motor control
device, the capacitors must be disconnected from the
motor control device when the isolation contactor is open.
Active filters.
Active filters (e.g. for reactive power compensation) must
not be operated in parallel during operation of the motor
control unit.
NOTICE
24 V DC supply voltage (L+, L-) provides a maximum of 55 mA
(recommended only for inputs).
NOTICE
Check that no liquids, dust or conductive objects can get into the
soft starter.
NOTICE
Can cause property damage.
If the motor heat output is set too high the motor may heat up more
than is permissible. If necessary integrate the thermoclick/PTC in
the circuit to protect the motor.
NOTICE
The connection of the 3-phase network supply to the main terminals
T1/T2/T3 is not permissible.
NOTE
This is a product for environment A. When used in a household set-
ting, this device can cause unwanted radio interference. In this case
the user may be required to carry out appropriate measures to avoid
such radio interference.
