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 (PA/+ and PC/-) 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. Do
not repair or operate the product.
• Install and close all covers before applying voltage.
Failure to follow these instructions will result in death or serious injury.

The metal surfaces of the product may reach 150°C (302°F) during operation.
WARNING
HOT SURFACES
Ensure that any contact with hot surfaces is avoided.
Do not allow flammable or heat-sensitive parts in the immediate vicinity of hot surfaces.
Verify that the heat dissipation is sufficient by performing a test run under maximum load
conditions.
Failure to follow these instructions can result in death, serious injury, or equipment
damage.
CAUTION
SHARP EDGES
Use all necessary personal protective equipment (PPE) such as gloves when performing
any type of work whatsoever on or with the braking resistor.
Ensure that no other persons can perform any type of work whatsoever on or with
the braking resistor unless such persons use all necessary personal protective equipment
(PPE) such as gloves.
The cut resistance of the gloves must be at least level C as per ISO 23388 or
level A2 as per ANSI/ISEA 105.
Failure to follow these instructions can result in injury or equipment damage
