to assure safe operation under prevailing conditions. Proper
guards and other suitable safety devices or procedures as
may be desirable or as may be specified in safety codes
should be provided, and are neither provided by ABB nor
are the responsibility of ABB. This unit and its associated
equipment must be installed, adjusted and maintained by
qualified personnel who are familiar with the construction
and operation of all equipment in the system and the
potential hazards involved. When risk to persons or property
may be involved, a holding device must be an integral part
of the driven equipment beyond the speed reducer output
shaft.
WARNING: To ensure the drive is not unexpectedly
started, turn off and lock-out or tag power source before
proceeding. Failure to observe these precautions could
result in bodily injury.

arranged relative to the mounting positions as follows:
Horizontal Installations
-Install the magnetic drain plug in
the hole closest to the bottom of the reducer. Throw away
the tape that covers the filter/ventilation plug in shipment
and install plug in topmost hole. Of the 3 remaining plugs
on the sides of the reducer, the lowest one is the minimum
oil level plug.
Vertical Installations
-Install the filter/ventilation plug in
the hole provided in the top face of the reducer housing.
Use the hole in the bottom face for the magnetic drain plug.
Of the 5 remaining holes on the sides of the reducer, use
a plug in the upper housing half for the minimum oil level
plug.

Figure 1 - Mounting Positions
The running position of the reducer in a horizontal application is
not limited to the four positions shown in Figure 1. However, if
running position is over 20º either way in position “B” and “D”,
or 5º either way in position “A” or “C,” the oil level plug cannot
be safely used to check the oil level, unless during the checking
the torque arm is disconnected and the reducer is swung to
within 20º for position “B” or “D” or 5º for position “A” or “C” of
the positions shown in Figure 1. Because of the many possible
positions of the reducer, it may be necessary or desirable to
make special adaptations using the lubrication fitting holes
furnished along with other standard pipe fittings, stand pipes
and oil level gauges as required.
Installation
NOTE: This r
educer is compatible with the ABB Ability
Smart Sensor, that can be installed in the adapter plug
labelled “smart sensor”. The plug and sensor can be
moved to different locations as required by mounting
position.
1. Replace the plastic plugs that protect the threaded holes
in the reducer housing with the eyebolt supplied with the
reducer.
2. Determine the mounting position of the reducer (Figure 1).
Note that the reducer is supplied with either 4 or 7 plugs;
4 around the sides for horizontal installations and 1 on
each face for vertical installations. These plugs must be
