Replacement Parts and Maintenance

Schneider Electric provides a limited number of replacement parts for the ATV960 Process drive. Before replacing any parts, consult your local field sales representative. Replacements parts must be installed by qualified personnel familiar with the equipment being replaced.

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH Read and understand the precautions 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. Many parts of this equipment, including the printed circuit boards, operate at the line voltage. DO NOT TOUCH. Use only electrically-insulated tools. DO NOT touch unshielded components or terminal strip screw connections with voltage present. DO NOT short across terminals PA/+ and PC/- or across the DC bus capacitors. Before servicing the equipment disconnect the power, including the external control power that may be present. The circuit breaker or disconnecting switch does not always open all circuits. Lock the circuit breaker or disconnecting switch in the opened position. Place a “DO NOT TURN ON” label on the circuit breaker or disconnect switch of the enclosed drive. Wait 15 minutes to allow the DC bus capacitors to discharge. Then follow the “DC Bus Voltage Measurement Procedure” in document NHA60269 to verify that the DC voltage is less than 42 V. The enclosed drive LED is not an indicator of the absence of DC bus voltage. Install and close all covers before applying power or starting and stopping the equipment. Failure to follow these instructions will result in death or serious injury.

Electronic door interlocks, when provided, electrically lock the enclosure doors when control power is present. See Electronic Door Interlocks. Electronic door interlocks are provided on a door that cannot be interlocked with a through-the-door disconnect handle, such as on a multi-door enclosed drive. A door switch on the main door, when closed, allows the electronic locks to engage.

To open the doors, turn the circuit breaker off.

To engage the electronic door interlock, close all doors and turn the circuit breaker on. Turning on the circuit breaker with a door open will cause the circuit breaker to trip.

hazard of electric shock, explosion, or arc flash Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices. See NFPA® 70E® Standard for Electrical Safety in the Workplace®, NOM-029-STPS – Maintenance of Electrical Installations in the Workplace, Safety Conditions, or CSA Z462 or local equivalent. This equipment must only be installed and serviced by qualified electrical personnel. Turn off all power supplying this equipment before working on or inside equipment. Always use a properly rated voltage sensing device to confirm power is off. Replace all devices, doors, and covers before turning on power to this equipment. Failure to follow these instructions will result in death or serious injury.

The ATV960 process drive includes filtered forced air ventilation that prevents excess dust or debris from entering the enclosure. The filters require periodic maintenance and replacement. Replacement or cleaning of filters is suggested once every six months at minimum, but the frequency may increase depending on a number of environmental factors. Select a maintenance cycle that is appropriate for your installation conditions.

1. Remove all power from the enclosed drive.

2. Turn the circuit breaker and handle assembly to the Off position and open the enclosure door.

3. Test for the absence of voltage.

   NOTE: Verify that the voltage tester is functioning properly before and after testing for the absence of voltage.

4. Unlock the air outlet grill with a flat head screwdriver and lift the grill to the top. See Changing Front Filters.

5. Remove the grill and filter mat. Discard the filter mat.

6. Press the air outlet grill and the new filter mat into the cut out until it locks with an audible noise.

Service of the exhaust filter is typically not required unless environmental conditions are especially dusty or the equipment has not been operated for an extended period of time. To access the exhaust fan filter:

1. Remove all power from the enclosed drive.

2. Turn the circuit breaker and handle assembly to the Off position and open the enclosure door.

3. Test for the absence of voltage.

   NOTE: Verify that the voltage tester is functioning properly before and after testing for the absence of voltage.

4. For Type 3R equipment, refer to Accessing the Lifting Brackets and follow the instructions for removing the rain hood.

5. For Type 12 equipment, remove the vent grill as illustrated in Accessing the Exhaust Fan Filters on Type 12 Equipment.

Service (clean or replace) the exhaust fan filter following the instructions in Servicing the Front Fan Filters (without Rain Hood) for the front filters. Always replace the rain hood or top cover and thumb screws after cleaning or replacing the filter.
