SAFETY MESSAGES
Read these instructions carefully and look at the equipment to become
familiar with the device before trying to install, operate, service or maintain it.
The following special messages may appear throughout this bulletin or on
the equipment to warn of potential hazards or to call attention to information
that clarifies or simplifies a procedure.
The addition of this symbol to a Danger or Warning safety label indicates
that an electrical hazard exists which will result in personal injury if the
instructions are not followed.
!
This is the safety alert symbol. It is used to alert you to potential personal
injury hazards. Obey all safety messages that follow this symbol to avoid
possible injury or death.
DANGER
DANGER indicates an imminently hazardous situation which, if not
avoided, will result in death or serious injury.
WARNING
WARNING indicates a potentially hazardous situation which, if not
avoided, can result in death or serious injury.
CAUTION
CAUTION indicates a potentially hazardous situation which, if not avoided,
can result in minor or moderate injury.
CAUTION
CAUTION, used without the safety alert symbol, indicates a potentially
hazardous situation which, if not avoided, can result in property damage.
The signal word is followed by a statement of the hazard (for example,
electric shock) and may be accompanied by a pictogram depicting the
hazard or additional descriptive information concerning the hazard.
Following the statement of hazard is information on how to avoid or mitigate
the hazard.
The last portion of the hazard message states the consequences of failure to
follow the information contained in the hazard message.

QUALIFIED PERSONNEL
Qualified personnel are people who, by technical training, knowledge, and
experience, are able to assess the work to be done and to recognize and
avoid possible hazards. Qualified personnel will be aware of the current
standards, regulations, and accident prevention regulations that must be
observed when working on the apparatus.
EQUIPMENT DISPOSAL
When servicing or decommissioning, dispose equipment according to the
applicable standards for this classification of equipment.
FOR MORE INFORMATION
Call your local Schneider Electric or Square D service center for assistance
and for with:

PRECAUTIONS
Price and delivery on replacement equipment.
Repairs to your servomotor.
Scheduling a factory-trained repair technician to visit your site.
Read and observe the precautions on pages 2–3 of this bulletin before
installing, operating, or servicing this equipment.
DANGER
HAZARDOUS VOLTAGE
• Read and understand this instruction sheet in its entirety before installing or operating the servomotor. Installation,
adjustment, repair and maintenance must be performed by qualified personnel.
• Disconnect all power before servicing servomotor. FOLLOW THE INSTRUCTIONS INCLUDED WITH THE SERVOMOTOR
CONTROLLER FOR BUS CAPACITOR DISCHARGE!
• The Servomotor can produce voltage at its terminals when the shaft is rotated! Prior to servicing, block the servomotor shaft
to prevent rotation.
• AC voltage from the controller or servomotor can couple voltage to unused conductors in the motor cable. Insulate both ends
of unused conductors in the motor cable.
• The User is responsible for conforming to all applicable code requirements with respect to grounding all equipment.
Supplement the motor cable grounding conductor with an additional ground conductor to the motor frame.
Before servicing drive system:
• Disconnect all power.
• Place a “DO NOT TURN ON” label on drive system disconnect.
• Lock disconnect in the open position.
Failure to follow this instruction will result in death or serious injury.

WARNING
TOPPLING HAZARD
The reaction torque developed on the frame of the servomotor can cause the frame to move. The motor frame must be securely
anchored to prevent movement or toppling during rapid acceleration or deceleration.
HOT COMPONENTS
Avoid contact with, and keep temperature sensitive materials away from, the motor frame during operation. Allow sufficient
clearance for proper cooling. Motor frame temperature may exceed 212°F (100°C).
STRONG LOCAL ELECTROMAGNETIC FIELDS
The motor can emit strong local electric and magnetic fields. These fields can disturb sensitive equipment. During operation,
individuals with pacemakers should keep away from the servomotor.
LOSS OF BRAKING TORQUE
The servomotor brake is a holding brake and is not intended for stopping service! Check brake for proper functioning after all
servicing. Check brake function after frequent EMERGENCY/POWER OFF braking.
LOOSE PARTS
Before operating the servomotor, check for the presence of loose keys and verify the security of all rotating parts.
Failure to follow this instruction can result in death, serious injury, or equipment damage.
CAUTION
DAMAGED EQUIPMENT
• Do not install or operate any servomotor or drive train machinery that appears damaged.
• Field repair of the motor is not possible. Schneider electric, Square D Company or an authorized service center must perform
repairs. Modification or opening of the motor housing voids the warranty.
Failure to follow this instruction can result in injury or equipment damage.
CAUTION
IMPROPER POWER SUPPLY
Direct connection to the mains will damage the servomotor. A servomotor controller is required for power.
AN INTERCHANGEABLE CONNECTOR DOES NOT INDICATE INTERCHANGEABLE WIRING
The ability to connect an existing power cable or the encoder cable from another manufacturer’s power amplifier to the Berger
Lahr servomotor does not assure wiring compatibility. When interconnecting the Berger Lahr servomotor to another
manufacturer’s equipment, validate that the cable conductors are connected as shown in this instruction sheet and the power
amplifier is compatible with the encoder.
MECHANICAL DAMAGE TO SERVOMOTOR
Damage to the motor can result if excessive force is used while pressing drive train components (sprockets, pulleys, etc.) to the
servomotor shaft. Do not exceed the axial force values found in this instruction sheet.
CONNECTOR OVERHEATING / DAMAGE
To prevent connector contact damage, the motor power cable connector must be completely engaged to the motor mating
connector. Turn the locking ring of the motor cable connector clockwise until the locking ring is tight against the shoulder of the
mating connector of the motor.
Failure to follow this instruction can result in equipment damage.
