When you are installing components, or when assembling the cabinet, tighten
these bolt sizes to the specified torque values.
Starter Identification A nameplate is attached to the right-side flange of the structure (Figure 1). See
the nameplate for information such as series number, section number, NEMA
(National Electrical Manufacturers Association) enclosure type, unit ratings,
and bus ratings.
IMPORTANT For installation of ArcShield™ arc resistant equipment, refer to
Chapter 2.
IMPORTANT For information on the installation site preparation, see General
Handling Procedures for MV Products, publication MV-QS050.
ATTENTION: Use personal protective equipment (PPE) per local codes
or regulations. Failure to do so can result in severe burns, injury, or
death.

Door Opening Procedure Opening the Low Voltage Doors
Low voltage door is identified as LV in Figure 3.
1. To access the low voltage compartment, use a flat-head screwdriver to
turn both 1/4-turn fasteners on the low voltage door, counterclockwise
90°. See Figure 3.
2. The door is now released and swings open.
3. To secure the door, reverse the procedure.

Opening the Medium
Voltage Doors
Medium voltage (MV) doors are identified in Figure 4.
Figure 4 - Access to Medium Voltage Compartments, Standard Enclosure
The MV door has its own isolation switch handle and the interlocking
safeguards.
See Access to the Power Bus on page 14, for the procedure to open the swing-
out low voltage (LV) panel behind the low voltage (LV) door (for standard
cabinet only).
1. Press the STOP button on the starter or at the remote control location.
Both open the contactor electrically.
2. Move the isolation switch handle to the OFF position.
3. Unscrew the locking 3/8-1.75 bolts for the upper right-hand MV door.
The door is now released.
4. Open the upper right-hand MV door by swinging it open.

5. Pull the interlock release lever forward. The Interlock release lever is at
the bottom right corner of the door opening.
6. Open the bottom right-hand door by unscrewing the locking 3/8-1.75
bolts.
7. Unbolt and open the bottom left door.
8. Close the doors by reversing the procedure.
Anchoring Place the controller in the required installation location. Use M12 (1/2 in.) floor
mounting-bolts to fasten the controller to the mounting surface. See Figure 5
as an example of the location of the mounting holes in the cabinet.
IMPORTANT The bottom MV doors cannot be opened until the interlock release
lever is pulled forward.
IMPORTANT Verify that the swing-out low voltage panel is in its original position
before attempting to close the medium voltage (MV) door. When
closing the MV doors, verify all door locking-bolts on the right side
of the MV door are in place. Tightened the bolts until the door is
even with the flange. Do not over tighten the bolts. If the door is not
securely fastened, the isolation switch handle cannot be moved to
the ON position.
ATTENTION: Complete the Power Lockout Procedure on page 43 before
beginning any service procedures to the unit. Failure to do so can result
in severe burns, injury, or death.
IMPORTANT See the Dimension Drawing for additional details that are related to
the cabinet floor plan.
IMPORTANT Pre-determined cabinets are designed for Uniform Building Code
(UBC) seismic zone 1, 2A, 2B, 3, 4, and IBC (International Building
Code) seismic activity without overturning or lateral movement.
Provided they are securely mounted according to UBC, IBC, and the
local building codes. This restriction can include concrete pad
design, steel floor design and the sizing of cabinet anchors.
Concrete floor cutouts must not be next to floor anchor bolts and
must be sized to seismic load. If an accredited engineer must
review the floor mounting, consult the factory. Many jurisdictions
require an engineer from the local area to review the design.
Seismic qualification does not indicate that the equipment will
function properly after a seismic event.

Joining the Sections
1. Position the left side section on a level surface and secure the section in
place with M12 (1/2 in.) floor mounting-bolts (see Anchoring on page 12).
2. When joining NEMA/EEMAC Type 12 sections, apply a continuous
3 mm (0.125 in.) bead of silicon around the perimeter of one section.
3. Remove the side bus access covers, if applicable.
4. Position the right section against the left section. Make sure that the
surface is level.
5. Secure the sections together with 1/4-20 self-tapping screws (12 lb•ft
[15 N•m]). Thread the screw through the 0.281 in. clearance hole to the
corresponding 0.219 in. pilot hole. To access the front clearance holes of
the left-side cabinet, open the medium voltage (MV) doors. To access the
rear clearance holes, remove the rear covers of the starter. If rear access
is not available, refer to Front Access – Top Incoming Load Cables on
page 15 or Front Access – Bottom Incoming Line Cables on page 17.
6. Secure the right section to the floor using ½ in. (M12) floor mounting-
bolts (see Anchoring on page 12).

IMPORTANT FOR SEISMIC APPLICATIONS
For installations on concrete – the minimum depth and radius of
concrete that supports the cabinet anchors is dependent on
seismic loads. See Anchoring on page 12 for important information.
For installations on a metal structure – the metal plate depth and
the method to anchor the cabinet is dependent on seismic loads.
IMPORTANT The joining hardware can be found in a package mounted to the
front of the shipping skid. See Publication MV-QS050 requirements
for a level floor surface.

ATTENTION: This procedure requires contact with medium voltage (MV)
components. To avoid shock hazards and stop incoming power, do the
Power Lockout Procedure on page 43. Verify that all circuits are voltage
free by using a hot stick or appropriate device that measures voltage.
Failure to do so can result in severe burns, injury, or death.

8. Remove the retaining 1/4-20 self-tapping screws from removable bus
access barrier. The incoming cable connections to main bus are exposed
(see Figure 12).

9. Install the incoming line cables to power bus. Torque to recommended
values on page 9.
10. Reverse procedure after cables are installed.
Front Access – Bottom Incoming Line Cables
If the incoming cables in your cabinet enter the section from the bottom,
follow the same procedure as for Front Access – Top Incoming Load Cables on
page 15.
1. Open all power cell doors.
2. Locate incoming cable duct at rear left-hand side of power cell (see
Figure 13).
3. Remove the 1/4-20 self-tapping screws from the cable duct access-
barriers. Remove barriers.
4. Route and install incoming line cables up to power bus. Torque to the
recommended values specified on page 9.
5. Reverse procedure after cables are installed.

ATTENTION: Make sure that all barriers are installed before re-
energizing the equipment. Failure to do so can result in electrical faults,
damage equipment, or severe injury to personnel.

Load Cable Connections
1. Complete the Power Lockout Procedure on page 43.
2. Remove the appropriate cable conduit-opening plate from the cabinet
(see Figure 14…Figure 17). The plate can be punched or cut to mount
conduit.
3. Route load cables for the power cell before control cables. Pull the cables
into the cabinet through the appropriate opening (see
Figure 14…Figure 17).
4. Connect the cables to the terminal assembly and tighten the 1/2-13
hardware to 45 lb•ft (61 N•m).
5. Connect cable shields (if present) to the ground lug.
6. Reinstall the current transformer barrier and reassemble the cabinet.
Figure 14 - Access to Load Cable Conduit Openings (Top Exit Configuration Shown)
ATTENTION: To avoid shock hazards and lockout incoming power, do
the Power Lockout Procedure on page 43 before working on the
equipment. Verify that all circuits are voltage free by using a hot stick
or appropriate device that measures voltage. Failure to do so can result
in severe burns, injury, or death.
IMPORTANT The current transformers can be positioned for top or bottom cable
exit. Follow the appropriate procedure that is described for your
starter configuration.
IMPORTANT Cable size cannot exceed 1-1000 MCM, 2-750 MCM, 3-500MCM, or
4-500 MCM per phase.
Stress cones should be internal, non-skirted style only. Do not use
external (skirted-style) stress cones due to space considerations.
IMPORTANT See Dimensional Drawings that are provided with order
documentation for additional details that are related to cabinet
floor plan.
