Storage
1. Keep motors clean.
• Store indoors.
• Keep covered to eliminate airborne dust and dirt.
• Cover openings for ventilation, conduit connections, etc.to
prevent entry of rodents, snakes, birds, and insects, etc.
2. Keep motors dry.
• Store in a dry area indoors.
• Temperature swings should be minimal to guard against
condensation.
• Space heaters are recommended to prevent condensation.
• Treat unpainted flanges, shafts, and fittings with a rust
inhibitor.
• Check insulation resistance before putting motor into service.
(Consult manufacturer for guidelines).
3. Keep Bearings Lubricated.
• Once per month, rotate shaft several turns to distribute grease
in bearings.
• If unit has been stored more than one year, add grease before
start-up. (Refer to
“Lubrication Procedures” on page 9 ).
Installation 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” on page 7 ). Clean and
dry the windings as required. Never start a motor which has been wet
without having it thoroughly dried.
Safety
Motors should be installed, protected and fused in accordance with
latest issue of National Electrical Code, NEMA Standard Publication
No. MG 2 and local codes.
Eyebolts or lifting lugs are intended for lifting the motor only. These
lifting provisions 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.
Frames and accessories of motors should be grounded in accordance
with National Electrical Code (NEC) Article 430. For general
information of grounding refer to NEC Article 250. Rotating parts
such as pulleys, couplings, external fans, and shaft extensions should
be permanently guarded.
