clamping strap.

1.9 Storage

; Store the device, partially or fully assembled, in a dry and

weatherproof manner in the original packing in a clean environment.

; Protect the device from environmental impacts and dirt until the final

installation.

; We recommend storing the device for a maximum up to one year to

guarantee proper operation and longest possible service life.

; Even devices explicitly suited for outdoor use are to be stored as

described prior to being commissioned.

; Maintain the storage temperature, see

chapter 3.5 Transport and storage conditions.

1.10 Disposal

Operating instructions

4. CONNECTION AND START-UP

4.1 Connecting the mechanical system

WARNING
Hot motor housing

Fire hazard

→ Ensure that no combustible or flammable materials are

located close to the motor.

CAUTION
Cutting and crushing hazard when removing the motor
from the packaging

→ Carefully remove the device from its packaging. 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.

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 motor is a built-in component and features no electrically
isolating switch.

→ Only connect the motor to circuits that can be switched off

with an all-pole separating switch.

→ When working on the motor, you must switch off the

Translation of the original operating instructions

system/machine in which the motor 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 cross­section.
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 Idle current

Because of the EMC filter integrated for compliance with EMC
limits (interference emission and interference immunity), idle
currents in the mains cable can be measured even when the
motor is at a standstill and the mains voltage is switched on.

● The values lie in a range of typical < 250 mA.

● The effective power in this operating state (readiness for operation) is

simultaneously at typical < 4 W.

4.2.3 Residual current operated device

Only universal (type B or B+) RCD protective devices are
permitted. Like frequency inverters, RCD protective devices
cannot provide personal safety while operating the device.
When switching on the power supply of the device, pulsed
charge currents from the capacitors in the integrated EMC filter
can lead to the RCD protective devices triggering without
delay. We recommend residual current devices with a trigger
threshold of 300 mA and delayed triggering (super-resistant,
characteristic K).

4.2.4 Locked-rotor protection

Due to the locked-rotor protection, the start-up current (LRA) is
equal to or less than the nominal current (FLA).

Operating instructions

4.6 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.

; Route the connecting cables in the terminal box so that the terminal

box cover closes without resistance.

; Use all plug screws (the entire number). In doing so, insert the

screws manually to avoid damage to the thread.

4.7 Switch on device

; Inspect the device for visible external damage and the proper function

of the protective features before switching it on.

; Check the air flow paths of the fan for foreign objects and remove any

that are found.

; Apply the nominal voltage to the voltage supply.

; Start the device by changing the input signal.

4.8 Switching off the device

Switching off the device during operation:

; Switch on the device via the control input.

; Do not switch the motor (e.g. in cyclic operation) on and off via power

supply.

Switching off the device for maintenance work:

; Switch on the device via the control input.

; Do not switch the motor (e.g. in cyclic operation) on and off via power

supply.

; Disconnect the device from the supply voltage.

; When disconnecting, be sure to disconnect the earth wire connection

last.

6. MAINTENANCE, MALFUNCTIONS, POSSIBLE
CAUSES AND REMEDIES

Do not perform any repairs on your device. Return the device to ebm­papst for repair or replacement.

CAUTION
The motor restarts automatically when operating voltage
is applied, e.g. after a power failure.

Danger of injury

→ Keep out of the danger zone of the motor.

→ When working on the motor, switch off the mains supply

voltage and secure the latter from being switched on again.

→ Wait until the motor stops.

CAUTION
If control voltage is applied or a speed setpoint is stored,
the motor automatically restarts, e.g. after a power failure.

Danger of injury

→ Keep out of the danger zone of the device.

→ When working on the device, switch off the mains

supply voltage and secure the latter from being switched on
again.

→ Wait until the device stops.

→ After working on the device, remove any used tools or

other objects from the device.

If the device remains out of use for some time, e.g. when in
storage, we recommend switching the device on for at least
two hours to allow any condensate to evaporate and to move
