Installation and Maintenance Instructions

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH Read and understand the instructions in bulletin NHA60269, Drives Systems Installation and Maintenance, before performing any procedures in this bulletin. Failure to follow these instructions will result in death or serious injury.

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH Read and understand this manual before installing or operating the enclosed drive. Installation, adjustment, repair, and maintenance must be performed by qualified personnel. The user is responsible for compliance with national and local electrical codes with respect to grounding of all equipment. DO NOT short across terminals PA/+ and PC/-, the DC bus capacitors, or the braking resistor terminals. 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 terminal strip screw connections with voltage present. Motors can generate voltage when the shaft is rotated. Before performing any type of work on the drive system, block the motor shaft to prevent rotation. Before servicing the enclosed drive: Disconnect all power including external control power that may be present. Always use a properly rated voltage sensing device to confirm power is off. Place a “DO NOT TURN ON” label on all power disconnects. Lock all power disconnects in the opened position. WAIT 15 MINUTES to allow the DC bus capacitors to discharge. Then follow the “DC Bus Voltage Measurement Procedure” and “DC Bus Voltage Measurement Procedure for Altivar Process 660/680/960/980” in bulletin NHA60269, Drives Systems Installation and Maintenance, to verify that the DC voltage is less than 42 V. The drive LED is not an indicator of the absence of DC bus voltage. Before applying voltage to the drive system: If the mains input terminals and the motor output terminals have been grounded, remove the ground on the mains input terminals and the motor output terminals. Replace all devices, doors, and covers before turning on power to this equipment or starting and stopping the drive. Failure to follow these instructions will result in death or serious injury.

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH Do not install or operate any enclosed drive that appears damaged. If you find shipping damage, notify the carrier and your Schneider Electric sales representative. Failure to follow these instructions will result in death or serious injury.

CAUTION
RISK OF BURNS AND ROTATING FAN BLADES Make sure that the device is sufficiently cooled and that the permitted ambient conditions are maintained. Do not touch components inside the enclosure. Heat sinks, chokes, and transformers may remain hot after removing power. Before opening the enclosure, ensure that the fans are not running. After switching off the voltage supply, the device fans may continue running for some time. Failure to follow these instructions can result in injury or equipment damage.
