Preliminary information
Duties of the user

The product is intended for use in industrial and commercial systems.
In the case of installation in electrical systems or machines, it is prohibited to start the
proper operation of the product until it is determined that the machine meets the re-
quirements stipulated in the local laws and directives.
The standards given in the declaration of conformity apply to the product.
Inspect the shipment for damage as soon as you receive the delivery. Inform the ship-
ping company immediately about any damage. If the product is damaged, it must not
be assembled, installed or started up.
Installation / Assembly
The lifting eyebolts are designed to carry only the weight of the motor without gear
unit. Tighten installed lifting eyebolts. Mounted gear units have separate suspension
attachments, which must be used according to the gear unit operating instructions
when lifting the gearmotor. Do not mount any additional loads.
The installed lifting eyebolts are in accordance with DIN 580. Observe the loads and
regulations specified there. The tension force vector of the slings must not exceed a
45° angle in accordance with DIN 580.
If necessary, use suitable, sufficiently dimensioned handling equipment.
Observe the following notes when transporting the device:
• Always use all attachment points if available. The attachment points are designed
to carry only the mass of the product. Severe or fatal injuries. Do not apply any ad-
ditional loads.
• Ensure that the product is not subject to mechanical impact.
If the product is not immediately installed, it must be stored in a dry and dust-free loca-
tion. The product can be stored for up to 9 months without requiring any special mea-
sures before startup. Do not store the product outdoors.
Do not transport or store the product on the fan guard.
Note the following points during installation:
• Make sure that the supports are even, the foot and flange mounting is correct and
if there is direct coupling, align with precision.
Avoid resonance between the rotational frequency and the double supply system
frequency.
Release brake (for motors with mounted brake).
Turn the rotor by hand and listen for unusual grinding noise.
Check the direction of rotation in decoupled state.
Only install or remove belt pulleys and couplings using suitable devices (heat up).
Cover the belt pulleys and couplings with a touch guard. Avoid unacceptable belt
tension.
Establish any necessary pipe connections.
Mounting positions with the shaft end pointing upward must be equipped with a
cover to prevent foreign objects from falling into the fan. Ensure that ventilation o-
penings are not obstructed and that used air cannot be drawn in again straight
away. The same applies to air from adjacent units.

2.5.1 Restrictions of use
The following applications are prohibited unless the device is explicitly designed for
such use:
•Use in potentially explosive atmospheres
•Use in areas exposed to harmful oils, acids, gases, vapors, dust, and radiation
2.6 Electric work
Electric work
2.6.1 Carrying out electric work safely
Observe the following information to carry out electric work safely during installation
and maintenance:
• Electric work may only be carried out by electrically skilled persons.
• Always adhere to the 5 safety rules for working on electrical components:
– Disconnect
– Secure the drive against restart
– Check that no voltage is applied
– Ground and short-circuit it
– Cover or safeguard neighboring live parts
• When the device is switched on, dangerous voltages are present at all power con-
nections as well as at any connected cables and terminals. This also applies even
when the product is inhibited and the motor is at standstill.
2.6.2 Electrical connection
The connection must be a permanently secure electrical connection (no protruding
wire ends). Use the corresponding cable end equipment. Establish a safe PE connec-
tion. When the motor is connected, the distances to non-insulated and live parts must
not be shorter than the minimum values according to IS/IEC 60664 and national regula-
tions. With low voltage, the distances should be no shorter than the following values,
in compliance with IS/IEC 60664:
Nominal voltage VNDistance
≤ 500 V 3 mm
The terminal box must be free from foreign objects, dirt and humidity. Unused cable
entry openings and the connection box itself must be sealed so that they are dust- and
water-proof.
Secure the key(s) for the test run without output elements.
When operating low-voltage machines with brakes, check that the brake is functioning
properly before startup.
Observe the notes in chapter "Electrical installation".
Exceeding the stated tolerances in IS/IEC 60034-1 – voltage ± 10 % , frequency ± 5%,
curve shape, symmetry – increases the heating and influences ele c tromagnetic compa-
tibility.
Observe the wiring information and differing data on the nameplate as well as the
provided wiring diagram.

2.7. Startup/operation
Startup/operation
Risk of burns: The surface temperature of the product can exceed 60 °C during opera-
tion. Do not touch the product during operation. Let the product cool down before
touching it.
Do not deactivate monitoring and protection devices of the machine or system even
for a test run.
Depending on the degree of protection, products may have live, uninsulated, and
sometimes moving or rotating parts, as well as hot surfaces during operation.
Make sure that any existing transport protection is removed.
In the event of deviations from normal operation, switch the product off. Possible devi-
ations are increased temperatures, noise, or vibration, for example. Determine the
cause. Contact SEW-EURODRIVE if necessary.
Ensure that the terminal box is closed and screwed down before applying the supp ly
voltage.
Additional preventive measures may be required for applications with increased haz-
ard potential. Be sure to check the effectiveness of the protection devices after eve r y
modification.
Mechanical blocking or internal protective functions of the product can cause a motor
standstill. Removing the cause of this problem can result in the drive re-starting. Dis-
connect the product from the power supply before you start with troubleshooting.
Overheating of
motors with back-
stop /RS
With low motor speeds, the centrifugal forces are so low that the backstop sprags
brush against the inner and outer ring. This causes overheating of the friction s u r -
faces.
• Do not permanently operate motors with backstop /RS below lift-o ffspeed.
