2-2 Installation MN1240

Receiving Each Baldor Electric Motor is thoroughly tested at the factory and carefully

packaged for shipment. When you receive your motor, there are several

things you should do immediately.

1. Observe the condition of the shipping container and report any damage

immediately to the commercial carrier that delivered your motor.

2. Verify that the part number of the motor you received is the same as the

part number listed on your purchase order.

Storage If the motor is not put into service immediately, the motor must be stored in a

clean, dry and warm location. If the parts are not put into service immediately,

store them in a clean, dry and warm location. The motor must be protected

from moisture and condensation. Storage area should be a dust free

environment, maintained −25 degC to +85 degC and less than 90% relative

humidity non−condensing.

Unpacking Each Baldor motor is packaged for ease of handling and to prevent entry

of contaminants.

1. To avoid condensation inside the motor, do not unpack until the motor

has reached room temperature. (Room temperature is the temperature

of the room in which it will be installed). The packing provides insulation

from temperature changes during transportation.

2. When the motor has reached room temperature, remove all protective

wrapping material from the motor.

Handling Use proper care and procedures that are safe during handling, lifting,

installing, operating and maintenance operations. Improper methods may

cause muscle strain or other harm.

Repairs Baldor will not share any responsibility for damage caused by customer

attempt to repair or modify a motor. Consult Baldor for any service.

Prevent Electrical Noise

Electro−Magnetic−Interference (EMI), commonly called “electrical noise” may

adversely affect motor performance by introducing stray signals. Effective

techniques to reduce or prevent EMI include AC power filters, cable shielding,

separating signal wires from power wires and good grounding techniques.

Effective AC power filtering can be achieved by using properly installed

“Isolated AC Power Transformers” or “AC Line Filters”. Other techniques are:

S Install motor cables and signal wires in separate conduits.

S Do not route motor cables and signal wires in parallel. Separate cables

by at least 1 foot for every 30 feet of run.

S Cross signal and power wires at 90 degree angles to prevent inductive

noise coupling.

S Do not route signal wires over the vent openings of the servo drives.

S Ground all equipment using a single point ground system.

S Keep wires as short as possible.

S Ground both ends of the encoder cable and use twisted pair wires.

S Use shielded motor cables to prevent EMI from other equipment.
