Always observe all safety precautions and use all personal protective equipment
(PPE) as required by Local Site Procedures. This equipment is designed to minimize
exposure risk to the operator. Please use the cables, explained below, to attain a
safe distance from the breakers during racking. Always use appropriate PPE. Above
all, adhere to site specific regulations and requirements.
Before beginning the racking process, be sure that the breaker is open, verify that a
lockout/tag out is in place (LOTO) and allows racking of the breaker.

Depicted in figs. 1.1 and 1.2, the Smart Drive Bracket (SDB) mounts to the front of the
breaker by aligning two keyhole slots on the SDB with two Shoulder Nuts mounted on
the breaker.
Once hung on the breaker, the SDB features a mounting ring (red, figs. 1.1, 1.2) into which
the Motor Drive Unit (MDU) will fit. A Tool Adapter Assembly (TAA) couples with the MDU.
The mounting rings are spring-loaded to ensure a secure connection from the TAA and
the racking shaft.
Once the MDU is in place, the racking in/out function may be performed.
Fig. 1.2Fig. 1.1

Sequence Process
1. Pull back the collar on the MDU.
2. Insert the TAA in to the quick-
connect tool coupling.
3. Release the collar and pull the TAA
to ensure its locked in place.

As noted in the Overview, the SDB is equipped with a Tool Adapter Assembly (TAA). The
Motor Drive Unit (MDU) is equipped with a quick-connect tool coupling, which uses a collar
that slides back and the TAA inserts in to the coupling. When the coupling is released, the
TAA is secured in place.
Sequence Process
1. Attach a fully charged battery to
the MDU.
2. Set the locking pin to the open
position.
3. Insert the MDU equipped with the
TAA through the mounting rings.
4. Align and engage the TAA with the
racking shaft.
5. Release the locking pin, securing
the MDU in place.
6. Connect the SDB Automation
Cable to the MDU.

Sequence Process
1. Align the keyhole slots on the SDB
with the Shoulder Nuts.
2. Slide the SDB down into place.

The Portable Kit includes two 28V batteries. Before connecting the battery to the system,
make sure the battery is fully charged and is attached to the MDU. If preferred, an AC Power
Supply is available, negating the need of a battery.
The MDU intuitively fits into the SDB mounting rings (depicted in red), on top of which
is a locking pin (depicted in green, fig. 1.5). Set the locking pin to the open position. Insert
the MDU and align the TAA with the racking shaft through the racking port. Lock the
MDU into place by releasing the locking pin. When the pin fully engages, the MDU is
secure.
Once the MDU is secured to the SDB the Tool Adapter Assembly is engaged with the racking
shaft, connect the 50-foot SDB Automation Cable to the Motor Drive Unit.
Fig. 1.5
The SDB mounts easily on the face of the breaker by aligning two keyhole slots on the
SDB with two Shoulder Bolts that have been mounted on the breaker face. The SDB slides
downward into place and shouldn’t shake or move during the racking process.

The Handheld Controller connects to the MDU via a 50’ Automation Cable. If necessary
three cables may be tethered to achieve a safe distance of 150’. Once plugged in and
turned on, the Handheld Controller guides the user through the racking in/out procedure.
When racking in/out, if an obstruction or mechanism
failure occurs, the system will attempt to recover the
breaker to a safe position. Actions will be displayed
with an asterisk (*) in front of them. When done, the
position of the breaker will be displayed as determined by the recovery. Note the
location and approach with caution. Determine the cause of the failure and remedy
the situation prior to attempting additional remote racking.
NOTE: Attempting to stop or shutting down the system mid-process once it has started
is not recommended, as this will leave the breaker in an unknown position. The Remote
Racking System will only operate from “known” positions: connect or disconnect. The Remote
Racking System will not engage when the breaker is at a mid-point.
