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
DriveBracket(SDB)hangsontwoShoulder
Nuts to align a Intermediate Tool Adapter
(ITA) with the open/close lever. The SDB
operates a transmission connected to the
ITA, which engages with the open/close
lever.
Once the SDB is in place, a Motor Drive
Unit (MDU) couples with a Universal Tool
Adapter Assembly (UTAA), depicted in
yellow, to engage with the transmission
and activate the open/close function. This
can be performed by the operator at a
distance up to 150 feet.

Sequence Process
1. Pull back the collar on the MDU.
2. Insert the UTAA in to the quick-
connect tool coupling.
3. Release the collar, twist the UTAA
to ensure it’s locked in place.

As noted in the Overview, the SDB is equipped with a Universal Tool Adapter Assembly
(UTAA). The Motor Drive Unit (MDU) is equipped with a quick-connect tool coupling, which
uses a collar that slides back for the UTAA to be inserted into the coupling. When the
coupling is released, the UTAA 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
UTAA through the mounting rings.
4. Align and engage the UTAA with
the transmission.
5. Release the locking pin, securing
the MDU in place.
6. Connect the SDB Automation
Cable to the MDU.

Sequence Process
1. Before mounting, set the SDB to the
locked position.
2. Hang the SDB on the Shoulder Nuts,
aligning the Intermediate Tool
Assembly and the open/close lever.
3. Release the locked SDB with the
horizontal arm, engaging the ITA and
the lever.

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 UTAA with the SDB transmission, then 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 and fully connected to the Tool Adapter, connect the
50-foot SDB Automation Cable to the Motor Drive Unit.
Fig. 1.5
The SDB is mounted on two slide hinges. Before hanging the SDB, using the mounting
rings, depicted in red, hold the vertical handle and pull the bracket into the locked position.
Then lift the SDB into place, mounting it on the two Shoulder nuts. Once hung, using the
horizontal lever, release the SDB and fix the Intermediate Tool Adapter to engage with the
open/close lever. Once engaged, the SDB is in place.

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.
