Installing the Drawout Device in the Chassis

Drawout Device Handling Conditions

Connection or disconnection of the drawout device requires insertion of the racking handle. When chassis locking by keylocks, padlocks, or an open door lock is in place, the racking handle cannot be inserted.

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION OR ARC FLASH Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices. See NFPA 70E or CSA Z462 or local equivalent. This equipment must only be installed and serviced by qualified electrical personnel. Failure to follow these instructions will result in death or serious injury.

NOTICE
HAZARD OF EQUIPMENT DAMAGE Use the provided racking handle to rack the device into or out of chassis. Do not use power tools for racking. Do not turn the handle after position release button has popped out. Failure to follow these instructions can result in equipment damage.

NOTICE
HAZARD OF EQUIPMENT DAMAGE Chassis must be securely fastened when installing or removing the device. Before mounting the device, make sure that it matches the chassis. Failure to follow these instructions can result in equipment damage.

Step	Action
1	If the chassis is not installed yet in a switchboard or panelboard, securely fasten the chassis on a pallet.
2	Remove the racking handle from its storage space.
3	Check that the chassis indicator is in the disconnected position: If the chassis indicator is not in the disconnected position, follow the steps on disconnecting the drawout device.
4	Press the rail release tabs.
5	Pull out the drawout grips until the extension rails are fully extended. NOTE: The right-hand rail cannot be extended if the racking handle has not been removed.
6	Install the device on the extension rails by using appropriate lifting equipment. Check that the slots on the device are correctly aligned with the guides on the rails while bringing the device down.
7	Detach the lifting equipment.
8	Check that the device is in the open position.
9	Using both hands, push in the device so that the rails are inserted to the maximum in the chassis. Take care not to push the control unit.
10	Check that the rail release tabs are in the correct position. Result: The device is in the disconnected position.
