Safety Instructions
2 Safety Instructions
Preliminary
remarks
The following safety instructions refer primarily to the operation of gear
units.
When operating geared motors, please also observe safety instructions for motors in
the corresponding operating instructions.
Please refer to the additional safety instructions in the individual sections of
these operating instructions.
General During and after operation, geared motors and gear units contain live and moving
components and possibly hot surfaces.
All tasks related to transport, storage, installation/assembly, connection, startup,
service and maintenance may only be performed by qualified technical personnel
while strictly adhering to
• the pertinent detailed operating instruction(s) and circuit diagrams
• warning and safety labels on the gear unit/geared motor
• system-specific regulations and requirements
• national/regional regulations concerning safety and accident prevention
Serious personal injuries and material damage may occur through
• incorrect use
• wrong installation or operation
• inadmissible removal of required protective covers or of the housing
Intended usage These geared motors/gear units are intended for industrial systems. They comply with
existing standards and regulations. The technical data and information on approved
conditions can be found on the nameplate and in the documentation.
All these details must be observed!
Transport /
Storage
Inspect shipment for possible transport damages upon receipt. Immediately
inform the shipping company of any damages. Startup may have to be cancelled.
Fasten installed lifting eyebolts. They were designed for the weight of the geared motor/
gear unit; no additional loads may be applied.
If necessary, use appropriate and sufficiently dimensioned means of transport. Remove
existing shipping braces prior to startup.
Installation /
Assembly
Observe information in sections 3 and 4!
Commissioning /
Operation
Check the correct direction of rotation of the gear unit in its disengaged state (without
built-on geared motor). Pay special attention to unusual sliding noises during barring.
Secure the key for the trial run without output components. Do not deactivate monitoring
and protection devices – not even for the trial run.
If in doubt, modifications to normal operation (e.g. increased temperature, noises,
vibrations) may require that the geared motor be switched off. Determine the cause and
confer with SEW, if necessary.
Inspection /
Maintenance
Observe information in section 6!

Before you begin
3 Installation
3.1 Before you begin
The drive may
only be installed
if
• the entries on the nameplate of the geared motor match the supply voltage
• the drive is not damaged (no damage resulting from transport or storage)
• it is certain that the following requirements have been fulfilled:
– with all gear units: ambient temperature between 0 °C and +40 °C, no
oils, acids, gases, vapors, radiation, etc.
– with special versions: drive configured according to ambient conditions
– with Spiroplan®gear unit HW30 and helical-worm gear HS..:
no large external mass moments of inertia are present that could exert a restoring
load on the gear unit (with η’ (restoring) = 2 – 1/η< 0.5 self-locking)
3.2 Preliminary work
Output shafts and flange surfaces must be thoroughly cleaned of anti-corrosion agents,
contamination or similar impurities (use a commercially available solvent). Do not let the
solvent get in contact with the sealing lips of the oil seals – danger of damage to the
material!
Please note: The service life of the lubricant in the bearings is reduced if the unit is
stored ≥1 year.
Gear unit designs of the "extended storage" type have
• an oil fill suitable for the mounting position so the unit is ready to run (mineral oil).
Nevertheless, check the oil level prior to startup (see “Lubricant filling quantities" on
page 19).
• a partially higher oil level if synthetic oil is used. Correct the oil level prior to startup
(see “Lubricant filling quantities" on page 19).
3.3 Installing the gear unit
The gear unit or geared motor must be mounted/installed in the specified mounting
position (Spiroplan® gear units are not dependent upon mounting position) on a level1),
vibration-absorbing and torsionally rigid support structure. Do not tighten housing legs
and mounting flanges against each other.
At this point of assembly, please check that the oil filling is as specified for the mounting
position.
In case of design changes, adjust the lubricant filling amounts accordingly.
Where the mounting position of HS gear units is to be changed to mounting position M2,
please consult the SEW service department.
1) Maximum permitted flatness error for flange mounting (approximate value with reference
to DIN ISO 1101): with →flange 120 – 600 mm max. error 0.2 – 0.5 mm
The oil check and drain screws and the breather valves must be freely accessible!

Installing the gear unit
Use plastic inserts (2–3 mm thick) if there is a risk of electrochemical corrosion between
the gear unit and the driven machine (connection between different metals such as cast
iron and high-grade steel)! Also fit the bolts with plastic washers! Ground the housing
additionally – use the grounding bolts on the motor.
Installation in
damp areas or on
the outside
Gear units are supplied in corrosion-resistant versions for use in damp areas or in the
open air. Any damage to the paintwork (e.g. on the breather valve) must be repaired.
Gear unit
venting
All gear units are delivered by SEW ready for the mounting position with the breather
valve and transport fixture fitted.
Exception:
Gear units for extended storage, pivoting and inclined mounting positions are delivered
with a screw plug on the intended vent hole. Prior to startup, the customer must replace
the highest screw plug by the supplied breather valve on each individual gear unit!
•With geared motors (for extended storage, pivoting or inclined mounting position),
the supplied breather valve is located in the terminal box on the motor.
•With mount-on units that must breathe on the input side, a breather valve is
supplied in a plastic bag.
•With gear units in an enclosed design no breather valve is supplied.
Activating the
breather valve
Usually the breather valve is activated ex-works. Should this not be the case, the
transport fixture must be removed from the breather valve prior to the startup of
the gear unit!
Painting the gear
unit
If the drive is to be overpainted or partially repainted, ensure that the breather valve and
the oil seals are carefully covered with tape. Remove the tape strips after the paint work
is finished.

Figure 2: Correct mounting arrangement of a carrying wheel
• Only use a mounting device (see Figure 1) for installing input and output elements.
Use the center bore and the thread on the shaft end for positioning purposes.
•Never drive carrying wheels, etc. onto the shaft end by hitting them with a
hammer (damage to bearings, housing and the shaft)!
• Power transmission elements should be balanced after fitting and must not give rise
to any impermissible radial or axial forces (see Figure 2 / permitted values see the
"Trolley drive systems" catalog).
Note:
• Assembly is easier if you first apply lubricant to the output element or heat it up
briefly (80 to 100 °C).
Input and output elements such as carrying wheels must have protection against
contact!
Mechanical
clutch
The output can be mechanically separated from a continuously running motor by
activating the clutch.
Pole-switchable motors or motors controlled by frequency inverters should be engaged
at low output speeds.

Inspection and maintenance
6.3 Inspection and maintenance
Do not mix synthetic lubricants with each other and do not mix synthetic and mineral
lubricants!
Oil is the standard lubricant.
The location of the oil level plug, the oil drain plug and the breather plug for the different
mounting positions can be found in the corresponding figures (see section 8.1).
Checking
the oil level
1. Disconnect the drive and secure against unintentional switch-on!
Wait until the gear unit has cooled down – Danger of burns!
2. For modified mounting positions refer to Section 3.3!
3. For gear units with oil level plug:
Remove oil level plug, check oil level and adjust if necessary, replace oil level plug.
Checking the oil 1. Disconnect the drive and secure against unintentional switch-on!
Wait until the gear unit has cooled down – Danger of burns!
2. Remove some oil from the oil drain plug.
3. Check the oil consistency:
– viscosity
– if the oil is visibly strongly contaminated, it is recommended to change it sooner
than specified in the maintenance intervals in section 6.1
4. For gear units with oil level plug:
Remove oil level plug, check oil level and adjust if necessary, replace oil level plug.
Changing the oil Change the oil only when the gear unit is at operating temperature.
1.
Disconnect the drive and secure it against unintentional switch-on!
Wait until the gear unit has cooled down – Danger of burns!
Note: However, the gear unit must still be warm, otherwise the high viscosity of
excessively cold oil will make it harder to drain the oil correctly.
2. Place a container underneath the oil drain plug.
3. Remove the oil level screw, breather plug/breather valve and oil drain plug.
4. Drain all the oil.
5. Screw in the oil drain plug.
