Weights:Before proceeding with unpacking, it is important to know the gross weight of the breaker for properselection of handling equipment. Approx. Gross Weight of breaker with packing , adaptors & accessories (kg) 1.1 Visual InspectionBefore Unpacking,A) Inspect the carton for any damage. In case of visible damage to the carton, contact nearest L&T branch office before unpacking.B) Verify the breaker version and rating written on the carton with your order. ::RatingVersionSerial No. :Cat.

Rack-out the breaker to Disconnected position. Note: After removing the racking handle (15), the racking shutter automatically recloses only in distinct ‘Connected’ / ‘Test’ and ‘Disconnected’ positions (17). Hence, Breaker cannot be closed in any Intermediate positions to ensure User safety. Keeping OFF button (11a) pressed, open the Racking Shutter (16). In case Breaker is out of the panel or the panel door is open, gently press Racking Interlock (26) to defeat it.Note: Once racking shutter is opened, the breaker can not be closed, even by an electrical closing command.Pull the breaker out using pull-out handles (27). In Maintenance position, Breaker can be removed from the cradle by two persons (Fr.1) or by using a crane (Fr.2 & 3). Please refer 1.3 Handling.CAUTIONExcessive, forceful Racking-out beyond Disconnected position may lead to Product damage. For D/O Breakers remove the Transportation Cushion (2 Nos.) & it’s instruction label,before doing racking operation of the breaker.DISCONNECTEDCONNECTEDTake out the handle
