Manual

Warning
These instructions must be followed to ensure safe
and proper installation, operation and maintenance
of the motor. They should be brought to the attention
of all the persons who install, operate or maintain
this equipment.

1. General information

ABB motors are all fully factory tested and inspected
before shipping, however damage during shipment and
storage can occur. Motors not correctly matched to the
power supply and/or the load will not operate properly.
These instructions are intended as a guide to identify
and eliminate these problems before they are
overlooked or cause further damage.

1.1 Acceptance

Check carefully for any damage that may have occured
in transit. If any damage or shortage is discovered, do
not accept until an appropriate notation on the freight
bill is made. Any damage discovered after receipt of
equipment should be immediately reported to the
carrier.

1.2 Storage

A. Keep motors clean.
1. Store indoors.
2. Keep covered to eliminate airborne dust and dirt.
3. Cover openings for ventilation, conduit connections,
etc. to prevent entry of rodents, snakes, birds, and
insects, etc.
B. Keep motors dry.
1. Store in a dry area indoors.
2. Temperature swings should be minimal to prevent
condensation.
3. Space heaters are recommended to prevent
condensation.
4. Treat unpainted fl anges, shafts, and fi ttings with a
rust inhibitor.
5. Check insulation resistance before putting motor
into service.
C. Keep bearings lubricated.
1. Once per month, rotate shaft several turns to
distribute grease in bearings.
2. If unit has been stored more than one year, add
grease before start-up.

1.3 Transportation

Machines fi tted with cylindrical-roller and/or angular
contact ball bearings shall be fi tted with locking devices
during transport.

2. Installation

2.1 Uncrating and inspection

After uncrating, check for any damage which may have
been incurred in handling. The motor shaft should turn
freely by hand. Repair or replace any loose or broken
parts before attempting to use the motor.
Check to be sure that motor has not been exposed to
dirt, grit, or excessive moisture in shipment or storage
before installation.
Measure insulation resistance (see operation). Clean
and dry the windings as required.
Never start a motor which has been wet without drying
it thoroughly.

2.2 Safety

Motors should be installed, protected and fused in
accordance with latest issue of National Electric Code,
NEMA Standard Publication No. MG 2 and local codes.
Eyebolts or lifting lugs are intended for lifting the motor
only. These lifting devices should never be used when
lifting or handling the motor with other equipment (i.e.
pumps, gear boxes, fans or other driven equipment) as
a single unit. Be sure the eyebolt is fully threaded and
tight in its mounting hole.
Eyebolt lifting capacity ratings is based on a lifting
alignment coincident with the eyebolt centerline.
Eyebolt capacity reduces as deviation from this
alignment increases. See NEMA MG 2.
Rotating parts such as pulleys, couplings, external fans,
and shaft extensions should be permanently guarded.

2.3 Location

In selecting a location for the motor, consideration
should be given to environment and ventilation. A motor
with the proper enclosure for the expected operating
condition should be selected.
The ambient temperature of the air surrounding the
motor should not exceed 40°C (104°F) unless the motor
has been especially designed for high ambient
temperature applications. The free fl ow of air around
the motor should not be obstructed.
The motor should never be placed in a room with a
hazardous process, or where fl ammable gases or
combustible material may be present, unless it is
specifi cally designed for this type of service.
1. Drip proof (open) motors are intended for use
indoors where atmosphere is relatively clean, dry or
non-corrosive.
2. Totally enclosed motors may be installed where dirt,
moisture and corrosion are present, or in outdoor
locations.
