Water enters at the cable end on the customers side and can
damage the device.

→ Make sure that the cable end is connected in a dry

environment.

Connect the device only to circuits that can be switched off
using an all-pole disconnecting switch.

4.2.1 Prerequisites

; Check whether the data on the type plate agree with the connection

data and the data of the operating capacitor.

; Before connecting the device, ensure that the supply voltage matches

the operating voltage of the device.

; Only use cables designed for current according to the type plate.

For determining the cross-section, follow the basic principles in
accordance with EN 61800-5-1. The protective earth must have a
cross-section equal to or greater than the outer conductor cross­section.
We recommend the use of 105°C cables. Ensure that the minimum
cable cross-section is at least
AWG26/0.13 mm².

4.2.2 Residual current operated device

Only pulse-current sensitive and/or universal RCD protective
devices (Type A or B) are permitted. Like frequency inverters,
RCD protective devices cannot provide personal safety while
operating the device.

4.2.3 Voltage control

With open loop speed control using transformers or electronic
voltage regulators (e.g. phase angle control), excessive current
may occur.
In addition, noises can occur with phase angle control
depending on the mounting situation.

4.2.4 Frequency inverter

Please use a frequency converter only after consultation with ebm-papst.
When a frequency converter is used for speed adjustment, the
maximum safe operating speed (see 3.2 Nominal data) may not be
exceeded.

Fit sinusoidal filters that work on all poles (live-live and live­earth) between the frequency inverter and the motor for
operation with frequency inverters.
Depending on how the device is installed, noises may occur.

Heating of the motor due to use of a frequency converter must be
checked in the application by the customer.

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.
