1.0 Installation
DANGER!
Ensure that the switch to be serviced matches the switch shown on cover. If the switch to be
serviced does not match, please call CBS ArcSafe® for more information regarding remote
switching applications for your particular model.
1. Remove the bolt located above the switch and replace it with the
provided threaded stud as shown in the ollowing pictures.
Tighten stud and ensure that the through hole in the stud is
vertically aligned.
2. Remove the cover that houses the stock tooling by removing the
two bolts that hold it in place. Remove the original tooling as well
and set aside with cover.

3. Insert the provided replacement tooling into the switching mechanism. Ensure
that it is ully engaged into the switching mechanism be ore continuing. Do not
replace the tooling cover, it will not be needed or the remote switching
procedure.
4. Install the RSA onto the switchgear in the ollowing steps:
a) Place the RSA onto the switchgear by inserting the threaded stud into
the hole in the upper le t corner o the RSA, all the while ensuring
that the protruding spring loaded sha t rom the motor engages with
the tooling inserted into the switch. Place the provided pin through
the stud to secure the RSA to the switchgear.
b) Turn the handle o the single twist lock magnet 180° clockwise to
engage the magnet and ully secure the RSA to the switchgear.
Ensure the magnet is ully seated against the panel be ore
continuing.
ATTENTION!
he location of certain items such as mimic bus, stickers, and/or placards may interfere with
the installation of the RSA. hese items may need to be removed or repositioned for proper
RSA installation.
5. Next, index motor sha t using the T-handle on the end o the sha t so that the
hole in the spring loaded sha t aligns with the hole in the tooling. Pin these
components together using the provided pin as shown in the ollowing picture.
6. Once again ensure that the tooling is ully engaged in the switching mechanism.
7. The RSA is now properly installed onto the switch. See the next section or the
charging operation details.

2.0 Charging Operation
DANGER!
Ensure that all applicable interlocks are defeated before beginning any remote switching
operation on the switchgear. Failure to do so will damage interlocks, switchgear, and/or
RSA. Please follow all applicable operation instructions and take necessary precautions as
stated in the switchgear operation manual.
1. Connect the our pin connecter rom the RSA-138 Inter ace Module to the
control box located on the right side o the RSA.
2. Connect the our pin connecter rom the RSO-I AR to the plug located on the
RSA-138 Inter ace Module.
3. Set the two position selector switch on the RSA-138 Inter ace Module to the
setting labeled “Charging Motor.”
4. Power on the RSO-I AR.
5. Press and hold the applicable button or the charging operation to be
completed. For example, i the switch is open and is to be closed, press and
hold the “CLOSE” button on the RSO-I AR to charge the switch to close. This
charging mechanism requires approximately 6.5 revolutions to charge the
springs. Hold the applicable button on the RSO-I AR until the drive motor ully
charges the springs and stops rotation.
6. The switch is now charged and is ready to be either closed or opened. See the
next section or applicable closing and opening operational details.
ATTENTION!
he RSA-138 Interface Module allows the operator to choose which operation to control.
his interface module must be used with this device. he RSA will not operate properly
without it. Failure to comply will lead to problems during the remote switching operation.
Please ensure that all cables are clear of moving parts. Failure to do so could damage cables
and/or actuator.

3.0 Closing/Opening Operation
DANGER!
Ensure that all applicable interlocks are defeated before beginning any remote switching
operation on the switchgear. Failure to do so will damage interlocks, switchgear, and/or
RSA. Please follow all applicable operation instructions and take necessary precautions as
stated in the switchgear operation manual.
1. Ensure that the switch is ully charged as outlined in the previous section.
2. Next, pull the spring-loaded sha t outward using the T-handle on the backside o
the sha t to disengage the tooling rom the switching mechanism and bypass the
interlock. With the sha t disengaged, rotate it slightly to ensure that when it is
released it will not engage the switching mechanism.
3. On the RSA-138 Inter ace Module, switch the two position switch to the setting
labeled “Open/Close Actuator.”
4. Power on the RSO-I AR and ensure that the AR unction is “ON.”
5. To per orm the applicable opening or closing operation press and hold the
“CLOSE” button to extend the linear actuator and engage the opening/closing
lever located above the sha t. The actuator will automatically retract when the
“CLOSE” button is released.
ATTENTION!
Please note that even if the desired effect is to open the switch, the “CLOSE” button must still
be pressed on the RSO-I AR. Because of this misnomer, operators must be aware of the
actions being performed on the switch.

DANGER!
*Ensure that personnel using this equipment are adequately trained in the operation
of the switchgear they are planning to work with; that they are correctly stationed
outside the arc flash boundary; and that they comply with all applicable Federal,
State, Local, and In-house safety regulations and procedures. Attention should be
given to distance, angle, and personal protective equipment (PPE).
