Operating instructions

W4E450-JP01-30

Translation of the original operating instructions

4.5 Checking connections

;

Ensure isolation from supply (all phases).

;

Make sure a restart is impossible

;

Check the cables for proper fit.

4.6 Switching on the device

The device may only be switched on if it has been installed properly and
in accordance with its intended use, including the required safety
mechanisms and professional electrical hookup. This also applies for
devices which have already been equipped with plugs and terminals or
similar connectors by the customer.

WARNING
Hot motor housing

Risk of fire
→ Ensure that no combustible or flammable materials are

located close to the fan.

;

Before switching on, check the device for visible external damage
and make sure the protective devices are functional.

;

Check the fan's air flow paths for foreign matter and remove any
foreign matter found.

;

Apply the nominal supply voltage.

NOTE
Damage to the device from vibration

Bearing damage, shorter service life
→ Low-vibration operation of the fan must be ensured over the

entire speed control range.

→ Severe vibration can arise for instance from inexpert

handling, transportation damage and resultant imbalance or
be caused by component or structural resonance.

→ Speed ranges with excessively high vibration levels and

possibly resonant frequencies must be determined in the
course of fan commissioning.

→ Either run through the resonant range as quickly as

possible with speed control or find another remedy.

→ Operation with excessively high vibration levels can

lead to premature failure.

4.7 Switching off the device

;

Disconnect the device from the power supply at the supply line's
main switch.

;

When disconnecting, be sure to disconnect the ground connection last.

5. MAINTENANCE, MALFUNCTIONS, POSSIBLE
CAUSES AND REMEDIES

Do not perform any repairs on your device. Send the device to ebm-
papst for repair or replacement.

WARNING
Live terminals and connections even with device
switched off

Electric shock
→ Wait five minutes after disconnecting the voltage at all poles

before opening the device.

CAUTION
Electric charge on capacitor after device is switched off

Electric shock, risk of injury
→ Discharge the capacitors before working on the device.

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

Risk of injury
→ Keep out of the device's danger zone.
→ When working on the device, switch off the line voltage

and ensure that it cannot be switched back on.

→ Wait until the device comes to a stop.

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

Malfunction/fault

Possible cause

Possible remedy

Impeller not
running smoothly

Imbalance in rotating
parts

Clean the device;
replace it if imbalance
persists after cleaning.
Make sure no
weight clips are
removed during
cleaning.

Motor not turning

Mechanical blockage

Switch off, isolate
from supply and
remove mechanical
blockage.

Line voltage faulty

Check line voltage,
restore power supply.

Faulty connection

Isolate from supply,
correct connection;
see connection
diagram.

Thermal overload
protector activated

Allow motor to cool
off, locate and rectify
cause of error,
release restart lockout
if necessary

Impermissible point of
operation

Check point of
operation

Motor
overtemperature

Ambient temperature
too high

Reduce ambient
temperature if possible

Deficient cooling

Improve cooling
