Translation of the original operating instructions
4.2.2 Residual current operated device
If the use of a residual current device (RCD) is required in your
installation, only pulse current-sensitive and/or universal
residual current devices (type A or B) are permissible.
Residual current devices (RCD) cannot provide personal safety
while operating the device, as is also the case with frequency
converters.
4.2.3 Voltage control
NOTE
Excessive current may occur with speed control using
transformers or electronic voltage regulators (e.g. phase angle
control). In addition, depending on how the unit is installed,
noise and vibration can occur with phase angle control.
Vibrations can lead to bearing damage, which can lead to
premature failure.
Heating-up of the motor when using voltage control must be checked by
the customer following installation in the end device.
4.2.4 Frequency inverter
Please use a frequency converter only after consultation with ebm-papst.
For operation with frequency converters, fit sinusoidal filters that
work on all poles (phase-phase and phase-earth) between the
frequency converter and the motor.
During operation with frequency converters, an all-pole sine
filter protects the motor against high-voltage transients that can
destroy the winding insulation system, and against harmful
bearing currents.
Heating-up of the motor when using a frequency converter must be
checked by the customer following installation in the end device.
4.3 Connection of the cables
External leads are brought out of device.
;
First connect the "PE" (protective earth) connection.
●
Connect the lines according to your application. When doing so,
observe chapter 4.4 Connection screen.
4.3.1 Motor protection
CAUTION
Voltage
The device is a built-in component with no isolating switch.
→ Connect the device to a suitable tripping device.
→ Only connect the device to circuits which can be de-
energised with an all-pole disconnection switch.
→ When working on the device, the system/machine in
which the device is installed must be secured so as to
prevent it from being switched back on.
NOTE
Lack of motor protection
Without motor protection, the motor can overheat and suffer
damage.
→ Connect up the thermal overload protector installed in the coil.
The motors are equipped with thermal overload protectors to protect the
devices.
Check to make sure that the thermal overload protector is correctly
connected before each operation.
Failure to connect up the thermal overload protector correctly will
invalidate your warranty claim.
