2.4 Designated use
The gear unit series R..7, F..7, K..7, K..9, S..7, SPIROPLAN® W is intended for use in
industrial systems.
The gear units may only be used according to the specifications in the technical docu-
mentation from SEW-EURODRIVE as well as the specifications on the nameplate.
They fulfill the applicable standards and regulations.
When installed in machines, startup (i.e. start of designated operation) is prohibited
until it is determined that the machine complies with the local laws and directives. In
the individual area of application, you must especially observe the Machinery Directive
2006/42/EC as well as the EMC Directive 2004/108/EC. The EMC test specifications
EN 61000-4-2, EN 61000-4-3, EN 61000-4-4, EN 61000-4-6 and EN 61000-6-2 must
be taken into account during startup.
Using these products in potentially explosive atmospheres is prohibited, unless specif-
ically designated otherwise.
2.5 Other applicable documentation
Observe the corresponding documentation for all connected devices.
2.6 Transportation/storage
Inspect the shipment for damage as soon as you receive the delivery. Inform the ship-
ping company immediately about any damage. If necessary postpone motor startup.
Tighten attached lifting eyes securely. The lifting eyes are designed to carry only the
weight of the motor/gear unit/gearmotor. Do not apply any additional loads.

10
The installed lifting eyebolts are in accordance with DIN 580. Observe the loads and
regulations specified there. If the motor/gear unit/gearmotor has 2 lifting eye lugs or
lifting eyebolts, then you should also use both lifting eye lugs for attaching transport
ropes. In this case, the tension force vector of the slings must not exceed a 45° angle
in accordance with DIN 580.
Use suitable, sufficiently rated handling equipment, that can be used for further trans-
port.
In case the motor/gear unit/gearmotor is not installed immediately store it dry, free of
dust and not outdoors. Do not store the motor/gearmotor on the fan guard. The motor/
gear unit/gearmotor can be stored for up to 9 months without requiring any special
measures before startup.
2.7 Installation
NOTICE
Danger due to static overdetermination if gear units with foot (e.g. KA19/29B,
KA127/157B or FA127/157B) are mounted both via the torque arm and via the foot
plate.
Risk of injuries and damage to property.
• Especially with the KA.9B/T design, it is not permitted to use the foot plates and
the torque arm at the same time.
• Attach the KA 9B/T design only via the torque arm.
• Attach the K.9 or KA.9B design only via the foot plate.
• If you want to use foot plates and torque arms for mounting, contact
SEW‑EURODRIVE.
Observe the notes in chapter "Mechanical installation (→ 2 22)".
2.8 Startup/operation
Check the oil level before startup as described in chapter Inspection/Mainte-
nance (→ 2 88).
Check for proper direction of rotation in decoupled state. Listen out for unusual grind-
ing noises as the shaft rotates.
Secure the key for the test run without output elements. Do not deactivate monitoring
and protection devices even for a test run.
Switch off the gearmotor if in doubt whenever changes occur in relation to normal op-
eration (e.g. increased temperature, unusual noise, vibration). Determine the cause. It
may be necessary to contact SEW‑EURODRIVE.
2.9 Inspection/maintenance
Observe the notes in chapter "Inspection/Maintenance"!
