Important Information
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.
NOTICE
Read these instructions carefully, and look at the equipment to become familiar with the device before trying to install, operate, or maintain
it. The following special messages may appear throughout this documentation or on the equipment to warn of potential hazards or to call
attention to information that clarifies or simplifies a procedure.
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, serious injury or
equipment damage.
CAUTION
CAUTION indicates a potentially hazardous situation which, if not avoided, can result in injury or equipment damage.
CAUTION
CAUTION, used without the safety alert symbol, indicates a potentially hazardous situation which, if not avoided, can
result in equipment damage.
PLEASE NOTE
The word "drive" as used in this manual refers to the controller portion of the adjustable speed drive as defined by NEC.

Before you begin
Read and understand these instructions before performing any procedure with this drive.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• Only appropriately trained persons who are familiar with and understand the contents of this manual and all other pertinent product
documentation and who have received safety training to recognize and avoid hazards involved are authorized to work on and with
this drive system. Installation, adjustment, repair, and maintenance must be performed by qualified personnel.
• The system integrator is responsible for compliance with all local and national electrical code requirements as well as all other
applicable regulations with respect to grounding of all equipment.
• Many components of the product, including the printed circuit boards, operate with mains voltage. Do not touch. Use only electrically
insulated tools.
• Do not touch unshielded components or terminals with voltage present.
• Motors can generate voltage when the shaft is rotated. Prior to performing any type of work on the drive system, block the motor
shaft to prevent rotation.
• AC voltage can couple voltage to unused conductors in the motor cable. Insulate both ends of unused conductors of the motor cable.
• Do not short across the DC bus terminals or the DC bus capacitors or the braking resistor terminals.
• Before performing work on the drive system:
- Disconnect all power, including external control power that may be present.
- Place a "Do Not Turn On" label on all power switches.
- Lock all power switches in the open position.
- Wait 15 minutes to allow the DC bus capacitors to discharge. The DC bus LED is not an indicator of the absence of DC bus voltage
that can exceed 800 Vdc.
- Measure the voltage on the DC bus between the DC bus terminals using a properly rated voltmeter to verify that the voltage
is < 42 Vdc.
- If the DC bus capacitors do not discharge properly, contact your local Schneider Electric representative.
• Install and close all covers before applying voltage.
Failure to follow these instructions will result in death or serious injury.
DANGER
UNINTENDED EQUIPMENT OPERATION
• Read and understand this manual before installing or operating the Altivar 312 drive.
• Any changes made to the parameter settings must be performed by qualified personnel.
Failure to follow these instructions will result in death or serious injury.
WARNING
DAMAGED DRIVE EQUIPMENT
Do not operate or install any drive or drive accessory that appears damaged.
Failure to follow these instructions can result in death, serious injury, or equipment damage.
WARNING
LOSS OF CONTROL
• The designer of any control scheme must consider the potential failure modes of control paths and, for critical control functions,
provide a means to achieve a safe state during and after a path failure. Examples of critical control functions are emergency stop,
overtravel stop, power outage, and restart.
• Separate or redundant control paths must be provided for critical control functions.
• System control paths may include communication links. Consideration must be given to the implications of unanticipated transmission
delays or failures of the link.
• Observe all accident prevention regulations and local safety guidelines.
• Each implementation of the product must be individually and thoroughly tested for proper operation before being placed into service.

Before you begin
CAUTION
INCOMPATIBLE LINE VOLTAGE
Before turning on and configuring the drive, ensure that the line voltage is compatible with the supply voltage range shown on the drive
nameplate. The drive may be damaged if the line voltage is not compatible.
Failure to follow these instructions can result in injury or equipment damage.
CAUTION
RISK OF DAMAGE TO THE MOTOR
The use of external overload protection is required under the following conditions:
• Repowering up the product since there is no motor thermal state memory.
• Running multiple motors.
• Running motors rated at less than 0.2 times the nominal drive current.
• Using motor switching.
Failure to follow these instructions can result in equipment damage

(1)These power ratings and currents are for a maximum ambient temperature of 50 °C and a switching frequency of 4 kHz in continuous
operation.The switching frequency is adjustable 2...16 kHz.
Above 4 kHz, the drive will reduce the switching frequency in the event of excessive temperature rise. The temperature rise is controlled
by a sensor in the power module. Nonetheless, the nominal drive current should be derated if operation above 4 kHz needs to be
continuous.
Derating curves are shown on page 15
