1 Important Notes
Safety and
warning
instructions
Always follow the safety and warning instructions contained in this publication!
A requirement of fault-free operation and fulfillment of any rights to claim under
guarantee is that the information in the operating instructions is adhered to.
Consequently, read the operating instructions before you start working with the drive!
The operating instructions contain important information about servicing; as a result,
they should be kept in the vicinity of the unit.
Waste disposal Please follow the current instructions:
• Housing parts, gears, shafts and anti-friction bearings of the gear units must be
disposed of as steel scrap. The same applies to gray cast iron castings unless there
are separate collection arrangements.
• Collect waste oil and dispose of it correctly.
Hazard
Possible consequences: Severe or fatal injuries.
Hazardous situation
Possible consequences: Slight or minor injuries.
Harmful situation
Possible consequences: Damage to the drive and the environment.

2 Safety Notes
Preliminary
remarks
The following safety notes are principally concerned with the use of gear units.
If using geared motors, please also refer to the safety notes for motors in the
corresponding operating instructions.
General
information
During and after operation, geared motors and gear units have live and moving parts
and their surfaces may be hot.
All work related to transport, putting into storage, setting up/mounting,
connection, startup, maintenance and repair only by trained personnel observing
•the corresponding detailed operating instructions booklet(s) and wiring
diagrams,
•the warning and safety signs on the gear unit/geared motor,
•the specific regulations and requirements for the system and
•national/regional regulations governing safety and the prevention of
accidents.
Severe injuries and damage to property may result from
• incorrect use,
• incorrect installation or operation,
• removal of required protective covers or the housing when this is not permitted.
Designated use These geared motors/gear units are intended for industrial systems. They correspond
to the applicable standards and regulations. The technical data and the information
about permitted conditions are to be found on the nameplate and in the documentation.
It is essential for all specified information to be observed!
Transport / putting
into storage
Inspect the delivery for any damage in transit as soon as you receive the delivery. Inform
the transport company immediately. It may be necessary to preclude startup.
Use suitable, sufficiently rated handling equipment if necessary. Remove any transport
fixtures prior to startup.
Store the gear unit in a dry, dust-free room if it is not going to be installed straight
away.

Before you begin
3 Setup and Installation
3.1 Before you begin
The drive may only be installed if
• the entries on the nameplate of the drive match the voltage supply system,
• the drive is undamaged (no damage caused by transport or storage) and
• it is certain that the following requirements have been fulfilled:
–with standard gear units: ambient temperature between -10 °C and +60 °C, no oil,
acid, gas, vapors, radiation, etc.
–with special versions: drive configured in accordance with the ambient conditions.
3.2 Required tools / resources
• Set of spanners
• Torque wrench (+ set of screwdrivers with a long hexagonal driver)
• Mounting device
• Shims and distance rings if necessary
• Fixing devices for input and output elements
• Lubricant (e.g. NOCO®fluid)
3.3 Preliminary work
The output shafts and flange surfaces of the motor to be mounted must be thoroughly
cleaned of anti-corrosion agents, contamination or such like (use a commercially
available solvent). Do not let the solvent come into contact with the sealing lips of the oil
seals – danger of damage to the material!
3.4 Installing the gear unit
The gear unit or geared motor may only be mounted or installed in the specified
mounting position on a level1, vibration damping and torsionally rigid support structure.
Use plastic inserts (2 – 3 mmthick) 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.
1. Maximum permitted flatness error for flange mounting (approximate values with reference to DIN ISO
1101): with flange 120 – 600 mm max. error 0.2 – 0.5 mm

In contrast to the PSF series, PSE gear units are installed on the existing machine using
tapped holes in the gearcase.

Mounting output elements
3.6 Mounting output elements
Fig. 3 shows a sample mounting device for installing couplings (3) or hubs onto motor
or gear unit shaft extensions (4). It may be possible to dispense with the thrust bearing
(2) on the mounting device.
When input and output elements are mounted on PSF series units, the shaft nut on
the input and output shaft must not be used as a stop for transmission elements (belt
pulley, pinion gear, etc.).
When input and output elements are mounted on PSE series units, the shaft shoulder
(Fig. 3, no. 1) is allowed to be used as a defined stop point.
Fig. 4 shows the correct mounting arrangement of a gear or sprocket in order to avoid
impermissibly high overhung loads.
• Only use a mounting device (see Fig. 3) for installing input and output elements. Use
the center bore and the thread on the shaft end for positioning purposes.
•Never drive belt pulleys, couplings, pinions, etc. onto the shaft end by hitting
them with a hammer (damage to bearings, housing and the shaft!).
•In the case of belt pulleys, make sure the belt is tensioned correctly (in
accordance with the manufacturer’s instructions).
• Transmission elements should be balanced after fitting and must not give rise to any
impermissible radial or axial forces (see Fig. 4 / for permitted values, see the "Low
Backlash Planetary Gear Units" catalog).

couplings
Couplings must be mounted and balanced according to the information provided by the
coupling manufacturer:
A Maximum and minimum clearance
B Axial misalignment
C Angular misalignment
Input and output elements such as belt pulleys, couplings, etc. must have
protection against contact!
Mounting is easier if you first apply lubricant to the output element or heat it up briefly
(to 80 – 100 °C).

Motor mounting with EK coupling
Proceed in this order:
•Placemotor (4) vertically (motor must have min. true-running accuracy to EN
42955). Use ring (5) to protect the encoder and other mounted components.
• Check smooth surfaces (6) of the motor and gear unit for scoring and smoothen them
if necessary. Clean and degrease the hollow shaft hole in coupling (11) and motor
shaft (3).
• Remove one or two of the four closing plugs (2). Turn the coupling (11) with clamping
ring (10) until the bolt head of clamping bolt(s) (8) is in alignment with the mounting
hole in the built-on housing. Unscrew the clamping bolt(s) (8). Motors with a
keyway: Turn the keyway 90° offset in relation to the slot in the coupling.
• If coupling sleeves (9) are used, make sure that the slots in the coupling sleeve (9)
are in alignment with the slots in the coupling (11) and clamping ring (10). Carefully
slide the gear unit onto the motor shaft (3).
• Insert bolts between the gear unit and motor and push their heads up to the hole.
Make sure the three oil screw plugs (7) can be accessed later. The oil screw plugs
are located on the top and bottom of the gear unit and on one side.
• Use a torque wrench (1) to tighten the clamping bolt(s) (8) to the prescribed
tightening torque.
• Center the gear unit on the coupling. To do this, unscrew the retaining screws and
then retighten in diametrically opposite sequence. Put the plug (2) back in.
All gear units only have one clamping bolt (8) except for types PSF/PSE 21. and PSF/
PSB/PSE 31. with motor shaft diameter ≤14 mm.
Never drive gear units, couplings, etc. onto the shaft end by hitting them with a
hammer (damage to bearings, housing and the shaft).
Gear unit types PSE, PSF 21. and PSF 31. do not have any oil screw plugs. Gear unit
type PSB has one oil screw plug (7) in the center of the flange block.

4Startup
4.1 Starting operation of low backlash planetary gear units
Check the direction of rotation is correct in decoupled status (also listen out for unusual
grinding noises as the shaft rotates).
Switch off the geared motor if in doubt whenever changes occur in relation to normal
operation (e.g. increased temperature, noise, vibration). Determine the cause; contact
SEW if necessary.
Secure the shaft keys for test mode without drive components. Do not render monitoring
and protection equipment inoperative even for test mode.
