Transport/storage
Safety Notes
2.6 Transport/storage
Inspect the shipment for any damage that may have occurred in transit as soon as you
receive the delivery. Inform the shipping company immediately. It may be necessary to
preclude startup.
Tighten the eyebolts securely. They are designed to only carry the weight of the
motor/gearmotor; do not attach any additional loads.
The built-in lifting eyebolts comply with DIN 580. Always observe the loads and regula-
tions listed in this standard. If the gearmotor is equipped with two eyebolts, then both
should be used for transportation. In this case, the tension force vector of the slings must
not exceed a 45° angle according to DIN 580.
Use suitable, sufficiently rated handling equipment if required. Reattach these in the
case of further transportation.
Store the motor/gearmotor in a dry, dust-free environment if it is not to be installed
straight away. You must not store the motor/gearmotor outdoors or on the fan guard.
The motor/gearmotor can be stored for up to 9 months without requiring any special
measures before startup.
2.7 Installation
Observe the notes in the "Mechanical Installation" chapter.
2.8 Startup/operation
Check the oil level before startup as described in chapter Inspection/Maintenance
(page 82).
Check that the direction of rotation is correct in decoupled status. Listen out for unusual
grinding noises as the shaft rotates.
Secure keys for test mode without output elements. Do not deactivate monitoring and
protection equipment even in test mode.
Switch off the gearmotor if in doubt whenever changes occur in relation to normal oper-
ation (e.g. increased temperature, noise, vibration). Determine the cause and contact
SEW-EURODRIVE, if required.
2.9 Inspection/maintenance
Observe the notes in chapter "Inspection/Maintenance".

4Installation requirements
Mechanical Installation
4.2 Installation requirements
Check that the following conditions have been met:
• The entries on the nameplate of the gearmotor match the voltage supply system.
• The drive has not been damaged during transportation or storage.
• Ensure that the following requirements have been met:
For standard gear units:
– Ambient temperature according to the technical documentation, nameplate and
lubricant table in section "Lubricants" (page 131).
– No harmful oils, acids, gases, vapors, radiation etc. in the vicinity
For special designs:
– The drive is designed in accordance with the ambient conditions. Observe the
information on the nameplate.
For helical-worm/SPIROPLAN®W gear units:
– No large external mass moments of inertia which could exert a retrodriving load
on the gear unit.
[for η’ (retrodriving) = 2 – 1/η< 0.5 self-locking]
For servo motor mounting:
– Do not assemble the drive without having ensured that there will be sufficient ven-
tilation after installation to prevent heat build-up.
• You must clean the output shafts and flange surfaces thoroughly to ensure they are
free of anti-corrosion agents, contamination or similar. Use a commercially available
solvent. Do not expose the sealing lips of the oil seals to the solvent – damage to the
material.
• When the drive is installed in abrasive ambient conditions, protect the output end oil
seals against wear.
CAUTION
Risk of injury due to protruding gear unit parts.
Minor injuries.
• Keep a sufficient safety distance to the gear unit/gearmotor.
NOTICE
Damage to the gear unit/gearmotor due to improper installation.
Possible damage to property
• Do closely observe the notes in this chapter.

Installing the gear unit
Mechanical Installation
4.3 Installing the gear unit
• Work on the gear unit only when the machine is not in use. Secure the drive unit
against unintentional power-up.
• Protect the gear unit from direct cold air currents. Condensation may cause water to
accumulate in the oil.
The gear unit or gearmotor is only allowed to be installed in the specified mounting
position. Observe the information on the nameplate. SPIROPLAN®gear units of size
W10 – W30 are mounting position-independent.
The support structure must have the following characteristics:
• Level
• Vibration damping
• Torsionally rigid
Maximum permitted flatness defect for foot and flange mounting (guide values with
reference to DIN ISO 1101):
Do not tighten the housing legs and mounting flanges against one another and ensure
that you comply with the permitted overhung and axial loads! Observe chapter "Project
Planning" in the Gear unit/gearmotor catalog for calculating the permitted overhung and
axial loads.
Secure gearmotors using quality 8.8 screws.
Secure the following gearmotors using quality 10.9 screws:
• RF37, R37F with flange Ø = 120 mm
• RF37, RF47, R47F with flange Ø = 140 mm
• RF57, R57F with flange Ø = 160 mm
• FF, FAF, KF, KAF with flange Ø 250 mm
• and RZ37, RZ47, RZ57, RZ67, RZ77, RZ87
CAUTION
Improper assembly may result in damages to the gear unit/gearmotor.
Possible damage to property
• Do closely observe the notes in this chapter.
CAUTION
Risk of jamming and crushing due to improper removal of heavy components.
Risk of injury.
• Removing the shrink disk properly.
• Observe the following removal notes.
• Gear unit size ≤67: Max. 0.4 mm
• Gear unit size 77 – 107: Max. 0.5 mm
• Gear unit size 137 – 147: Max. 0.7 mm
• Gear unit size 157 – 187: Max. 0.8 mm

4Installing the gear unit
Mechanical Installation
At the same time, also check that the oil fill corresponds to the specifications for the
intended mounting position (see chapter "Lubricant fill quantities (page 133)" or refer to
the information on the nameplate). The gear units are filled with the required oil volume
at the factory. There may be slight deviations at the oil level plug as a result of the mount-
ing position, which are permitted within the manufacturing tolerances.
Adjust the lubricant fill volumes and the position of the breather valve accordingly
in the event of a change of mounting position. Observe section "Lubricant fill quan-
tities (page 133)" and section "Mounting Positions (page 101)".
Consult the SEW customer service if you intend to change the mounting position of K
gear to M5 or M6 or between M5 and M6.
Please contact our SEW customer service if you want to change the mounting position
of size S47 – S97 helical-worm gear units to mounting position M2 or M3.
Use plastic inserts (2 – 3 mm thick) if there is a risk of electrochemical corrosion between
the gear unit and the driven machine. The material used must have an electrical leakage
resistance < 109Ω. Electrochemical corrosion can occur between various metals, for
example, cast iron and high-grade steel. Also fit the bolts with plastic washers. Ground
the housing additionally – use the grounding bolts on the motor.
INFORMATION
When installing the gear unit, make sure that the oil level and drain plugs as well as
the breather plugs are easily accessible!
