housing

Applications

MOVIMOT® units in category 3D comply with EN 50014 ("Electrical apparatus for po­tentially explosive atmospheres; general requirements", 2nd edition) and EN 50281-1­1:1998 ("Electrical apparatus for use in atmospheres containing flammable dust"), and
therefore conform to Directive 94/9/EC (ATEX 100a).

MOVIMOT® units in category 3D are supplied with enclosure IP54 at least. The enclo­sure has to be maintained over the complete operating time as a precondition for satis­fying the requirements for devices in category 3D. For this reason, particular care must
be taken even when connecting the units.

The unit must not be operated in zone 22 atmospheres if the enclosure type is not as­sured!

• Unit group II

• Category 3D

• For use in zone 22

• Surface temperature 140 °C

• Ambient temperature -20 to +40 °C

Installation toler­ances

Setting up
MOVIMOT

®

MOVIMOT® may not be installed unless:

• the entries on the name plate of the drive match the mains power supply,

• the drive is undamaged (no damage caused by transport or storage) and

• it is certain that the following requirements have been fulfilled:
– ambient temperatures between -20 °C and +40 °C (remember that the tempera-

ture range of the gear unit may be restricted → operating instructions for the

gear unit),
– no oil, acid, gas, vapors, radiation, etc.,
– installation altitude max. 1000 m above sea level.

Shaft end Flanges

Diametric tolerance in accordance with DIN 748

• ISO k6 at ∅ ≤ 50 mm

• ISO m6 at ∅ > 50 mm
(Center hole in accordance with DIN 332, shape DR)

→ ”MOVIMOT® Geared Motors” catalog, section ”Notes on Dimension Sheets.”

Centering shoulder tolerance in accordance with DIN
42948

• ISO j6 at ∅ ≤ 230 mm

• ISO h6 at ∅ > 230 mm

The MOVIMOT® may only be mounted or installed in the specified mounting position on
a level, vibration-proof and torsionally rigid support structure.

• Thoroughly remove anti-corrosion agents from the shaft ends (use a commercially
available solvent). Do not allow the solvent to penetrate the bearings and shaft
seals – this could cause material damage!

• Carefully align MOVIMOT

®

and the driven machine to avoid placing any unaccept­able strain on the motor shafts (observe permissible overhung load and axial thrust
data!).

• Do not butt or hammer the shaft end.

• Use an appropriate cover to protect motors in vertical mounting positions
from accidental entering of objects or fluids ! (Protection cowl C)

• Ensure an unobstructed cooling air supply and that air heated by other units cannot
be drawn in or reused.

• Balance components for subsequent mounting on the shaft with a half key (output
shafts are balanced with a half key).

5 Electrical Installation

It is essential to comply with the safety notes (see page 5) during installation!

5.1 Installation guidelines

When connecting up, comply with the following ElexV 1 provisions (or other nationally
valid regulations) in addition to the generally applicable installation regulations:

• EN 60 079-14 (“Installation of electrical systems in hazardous areas”)

• EN 50281-1-2 (“Electrical tools and fixtures for use in atmo spheres con taining
flammable dust”)

• DIN VDE 0105-9 (“Operation of electrical systems”)

• DIN VDE 0100 (“Setup of power installations up to 1000 V”)1)

• and provisions specifically relating to the system

Connecting supply system leads

Rated voltage and
frequency

• The rated voltage and frequency of MOVIMOT® must correspond to the data for the

mains supply.

• The cross sections of the cables used must be selected according to the rated cur­rent of the unit and the applicable installation regulations.

• The selection of the cable type is based on the applicable installation regulations
and the requirements at the application location.

Power terminals Control terminals

1.0 mm2 – 4.0 mm2 (2 x 4.0 mm2) 0.25 mm2 – 1.0 mm2 (2 x 0.75 mm2)
AWG17 – AWG10 (2 x AWG10) AWG22 – AWG17 (2 x AWG18)

• Use conductor end sleeves without insulating shrouds
(DIN 46228 part 1, material E-CU)

• All cable entries are supplied fitted with a closing plug.
To connect the unit, replac e the req uired nu mbe r of plug s with su itable cable entries
which are fitted with strain relief.

• The cable entries must meet the requirements of EN 50 014, 2nd edition.

• Select the cable entries on the basis of the diameter of the cables used. Please
refer to the documentation provided by the manufacturer of the cable entry for fur­ther information.

• Install the line protection at the start of the supply system lead behind the supply
bus junction (
breakers. The fusible rating should be selected in accordance with the cross section
of the cable.

• It is not permissible to use a conventional residual-current-operated circuit breaker
(r.c.c.b.) as a protective device. Universal current-sensitive residual-current-oper­ated circuit breakers (tripping current 300 mA) are permissible as a protective
device. Earth-leakage currents > 3.5 mA may occur during normal operation of the
MOVIMOT

• Contactor switch contacts in utilization category AC-3 to IEC 158 must be used for
switching MOVIMOT

• SEW recommends using earth-leakage monitors with a pulse code measuring
process in voltage power systems with a non-earthed star point (IT systems). This
avoids faulty tripping of the earth-leakage monitor due to the earth capacitance of
the inverter.

• The MOVIMOT® power supply should be either from an external 24 VDC voltage or

using the MLA12A options.

• Connect the required electronic control leads
(e.g. CW/STOP, CCW/STOP, setpoint changeover f1/f2).

• Use shielded cables as control leads and route them separately from power current
cables.

With PLC bus master or MLA12A option

• Important: Only ever connect one

• Use twisted pair shielded cables as control leads and route them separately fro m
