CONNECTION AND START-UP
4.1
Connecting the mechanical system
CAUTION
Cutting and crushing hazard when removing the
fan from the packaging.
→ Carefully remove the device from its packaging only
touching the guard grille. Make sure to avoid any
shock.
→ Wear safety shoes and cut-resistant safety gloves.
Check the device for transport damage. Damaged devices
must no longer be installed.
Install the undamaged device according to your application.
4.2
Connecting the electrical system
DANGER
Electric voltage on the device
Electric shock
→ Always install a protective earth first.
→ Check the protective earth.
DANGER
Incorrect insulation
Risk of fatal injury from electric shock
→ Use only cables that meet the specified installation
requirements for voltage, current, insulation material,
load etc.
→ Route cables such that they cannot be touched by
any rotating parts.
CAUTION
Electrical voltage
The fan is a built-in component and features no
electrically isolating switch.
→ Only connect the fan to circuits that can be switched
off with an all-pole separating switch.
→ When working on the fan, you must switch off the
installation/machine in which the fan is installed and
secure it from being switched on again.
NOTE
Water penetration into leads or wires
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.
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 cross- section.
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
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
4.2.3
Frequency inverter
Please use a frequency converter only after consultation with
ebm-papst A&NZ.
Fit sinusoidal filters that work on all poles (live-live
and live-earth) between the frequency inverters 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 the device.
First connect the “PE” (protective earth) connection.
Connect the lines according to your application. When
doing so, observe chapter 4.5 Checking the connections.

Checking the connections
Make sure that the power is off (all phases).
Secure it from being switched on again.
Check the correct fit of the connection lines.
