Translation of the original operating instructions

4. CONNECTION AND START-UP

4.1 Connecting the mechanical system

CAUTION

Cutting and crushing hazard when removing the device

from the packaging

Blades can be bent

→ Carefully remove the device from its packaging, only

touching the wall ring. Make sure to avoid any shock.

→ Wear safety shoes and cut-resistant safety gloves.

CAUTION

Heavy load when taking out the device

Bodily harm, e.g. back injuries, are possible.

→ Two people should remove the device out of its packaging

together.

; Check the device for transport damage. Damaged devices must no

longer be installed.

; Do not make any modifications, additions or renovations to the

device. Replacing the terminal box is not permitted.

; 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.

DANGER

Electrical load (>50 µC) between mains wire and

protective earth connection after switching of the supply

when switching multiple devices in parallel.

Electric shock, risk of injury

→ Make sure that sufficient protection against accidental contact

is provided.

Before working on the electrical connection, the

connections to the mains supply and PE must be shorted.

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.

Earth wire contact resistance to EN 61800-5-1

Compliance with the impedance specifications to EN 61800-5-1 for the

protective earth circuit must be verified in the end application.

Depending on the installation situation, it may be necessary to install an

additional protective earthing conductor via the additional protective earth

connection point available on the device.

The protective earth connection point is located on the housing and has

a protective earth symbol and a bore hole.

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 live-

earth) 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.
