Depicted in figs. 1.1 and 1.2, an Interlock
Manipulator is activated when plugged into the
Smart Drive Bracket (SDB), which engages with
the Motor Drive Unit (MDU). A Spanner Bar is
temporarily installed on which to mount the
SDB.
The Interlock Manipulator mounts on two
switch magnets inside the breaker door. The
SDB rests on the Spanner Bar and latches into
place with a spring lock. The MDU connects to
the SDB and connects the Handheld Controller
(HHC) with a 50-foot automation cable to allow
the operator to perform the racking in/out
functions from a safe distance.

The Portable Kit comes with a
Universal Tool Adapter Assembly
(UTAA) that is designed to be trimmed
to a specific length to accommodate
any breaker distance.

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.

Sequence Process
1. Fit the Spanner Bar to the
appropriate width.
2. Secure the Spanner bar in position

The Spanner Bar, depicted in fig. 1.3, mounts between the wall panels of the breaker.
The width of the Spanner Bar is adjustable and secures its position where the SDB can
be mounted.
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 SDB.
5. Release the locking pin, securing
the MDU in place.
6. Connect the SDB Automation
Cable to the MDU.

Sequence Process
1. Secure the Interlock Manipulator
with two switch magnets.
2. Secure the SDB to the breaker with
the spring lock.
3. Plug the SDB and the Interlock
Manipulator together.

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. 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
As depicted in fig. 1.4, the Interlock Manipulator mounts on two switch magnets and the
SDB rests on the Spanner Bar while a spring lock secures it to the breaker face. The two
connect via a cable so the Interlock Manipulator engages with the Interlock Handle to
perform the racking functions.

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.
