5 Transport and storage
Observe the safety instructions in Ch. Safety, from page 5 on.
Please refer to the brochure for weights and dimensions.
When transporting the NED, ensure that the NED is not subjected to
strong impacts or vibrations that could damage the bearings.
Please observe the following notes:
Use only the transport eyelet/eyelets (1) for lifting the NED. If the vibra-
tor is fitted with two transport eyes, both must be used for lifting.
The pulling direction must not exceed 45°.
Lifting tools are of the usual kind such as a pulley or a crane. When
moving loads, use suitable steel cables or hoisting slings which are suf-
ficiently dimensioned for these weights.
Handle the NED very carefully during transport.
The NED are packed ready for installation.
The packaging protects the NED from transport damage. The packaging
material has been selected from an environmentally safe and technically
disposable point of view and is therefore recyclable.
The return of packaging to the material cycle conserves raw materials and
reduces the amount of waste.
Store the NED in a dry and clean environment.
The permissible storage temperature is between -15 °C and +60 °C.
The permissible relative humidity is max. 60 %.
The storage time is max. 2 years.
Do not store the NED outdoors. The electrical components are not pro-
tected against corrosion.

6 Installation
Observe the safety instructions in Ch. Safety, from page 5 on.
Please refer to the brochure for weights and dimensions.
The NED can be operated in any position.
1. Notice: The feet of the NED must lie completely on the surface so that
there is no tension in the housing when tightening the fastening
screw/screws, which could cause mechanical damage. The mounting
surface has to be flat (±0.1 mm flatness) and clean with no paint resi-
dues or burn-ins.
2. The vibrators can be fastened with fastening screws of quality 8.8
(DIN 931 or 933). These must be secured with appropriate locking de-
vices and checked and retightened at regular intervals (usually month-
ly). For safe fastening Netter Vibration recommends the use of fas-
tening kits NBS consisting of a screw, a special lock washer and (for
NBS D) a nut.
Fasten the NED with the fastening screws on the mounting surface.
Use a torque wrench and tighten the screws crosswise. Observe the
recommended values for screw sizes and tightening torques, see
chap. Technical data, from page 7. Higher tightening torques may
cause fracture of screws or tearing of threads.
Warning: Unsuitable screw connections may cause loosening of the
NED by vibration. This can cause damage to persons and material.
3. Use an additional safety device for critical
installation situations, e.g. steel cable NSE.
Use the wire cable clamps to set the safety
cable to the shortest possible cable length.
The safety cable must always be ten-
sioned.

the NED

Installation
12
The following requirements and conditions must be met to connect the
NED electrically:
The electrical connection may only be carried out by authorised, quali-
fied personnel.
All work must be carried out exclusively with insulated tools suitable for
the application.
The permissible operating conditions must be met. Please refer to
chap. Technical data, page 7 for operating conditions.
The supply voltage must correspond to the information on the type
plate.
The permissible deviation of the supply voltage must be observed, see
chap. Technical data, page 7.
For the models NED 50100 up to NED 601510:
It is imperative to pay attention to the correct polarity, because the NED
will not start if the polarity is wrong.
A suitable overload protection (1) must be
pre-connected to each vibrator. The motor
protection switches must be interlocked with
each other in pairs, so that in the event of a
motor failure, the power supply from both
motors is interrupted at the same time in or-
der not to cause uncontrolled vibrations
which can damage the system.
All electrical cables must be carefully laid and must be protected from
high temperatures, lubricants and sharp edges. Care must be taken to
ensure that the cables are not chafed through by vibrating parts. The
correct condition of the electrical cables with their plugs must be
checked at regular intervals (usually every six months). Detected er-
rors are to be eliminated immediately.
The wire ends must be fitted with suita-
ble insulated cable lugs, in order to pre-
vent the strands from splaying.
Note that the models NED 50100 up to NED 601510 have a start delay of
approx. 1 second.

For all NED there is the possibility of unbalance adjustment to directly in-
fluence vibration amplitude, centrifugal force and current consumption.
Unless otherwise specified by you, the NED were delivered with the
standard setting (100 %). If specifications have been made by the custom-
er, there are stickers with the current setting on the unbalance covers.
Notice: The unbalances may only be set mirror-symmetrically!
Procedure:
1. Switch off the NED at the main switch, secure against unintentional
starting and ensure that there is no voltage.
2. Loosen both unbalance covers.
3. Loosen the locking nuts or locking screws.
4. Bring the unbalances to the desired setting according to the following
descriptions for the various unbalance discs. Note the mirror-
symmetrical setting.
5. Retighten the locking nuts or locking screws. Observe the recom-
mended tightening torques, see chap. Technical data, from page 7
6. Fasten both covers for the unbalances.
* For NED 5016: The two unbalance covers can be unscrewed using an oil
filter/strap wrench.
Adjustment of
unbalances

Start-up and operation
16
The NED has a total of 6 unbalance discs type XL.
The centrifugal force is adjustable with the unbalance discs (lamella) of
type XL in the following steps:
1: Number of unbalance discs per side
2: Default number of unbalance discs per vibrator
3: Centrifugal force in %
There are 2 possibilities to adjust the unbalances:
1. The unbalance adjustment (fine adjustment) is carried out by remov-
ing one unbalance disc on each side. All centrifugal values in % can
be adjusted as specified in the table.
The removed unbalance discs must be replaced by compensation
washers of identical thickness and identical inner diameter. These are
available from Netter Vibration.
2. The unbalance adjustment (coarse adjustment) is performed by turn-
ing one unbalance disc on each side by 180° on the shaft.
Twice the number of unbalance discs turned by 180° becomes inef-
fective.
The centrifugal force is adjustable with the unbalance discs (lamella) type
XLs. Adjustment of the unbalances is carried out according to a scale disc
or the supplementary sheet in the terminal box of the NED.
By rotating the outer, adjustable unbalance disc(s) to another position, the
percentage of the centrifugal force changes as shown in the illustration
below. The grid position is defined by position pins.
