Recommended Torque
Values
When reinstalling components, or when reassembling the cabinet, tighten the
following bolt sizes to the specified torque values:
Table 1 - Torque Values for Hardware
RecommendedLineandLoad
Cable Sizes
Environmental Conditions The controller must accept nominal plant power of 2400V, 3300V, 4200V,
4800V, 5500V, 6600V, 6900V (+5/-15%), or 7200V (+0/-15%), 3 PH,
50/60 Hz (± 3%).
The standard controller must operate in an ambient temperature range of
0…40 °C (32…104 °F) with a relative humidity of up to 95% (noncondensing).
Higher ambient temperature conditions are supported with factory assistance.
Store the equipment in an environment with an ambient temperature range of
-40…+85 °C (-40…+185 °F).
If storage temperature fluctuates or if humidity exceeds 85%, space heaters
must be used to prevent condensation. The equipment must be stored in a
heated building which has adequate air circulation.
Rockwell Automation products are built using materials that comply with
Class 1: Industrial Clean Air sulfur environments as defined in IEC Standard
60654-4 (Operating Conditions for Industrial-Process Measurement and
Control Equipment), and G1 as defined in ISO-S71.04-1985 (Environmental
Conditions for Process Measurement and Control Systems: Airborne
Contaminants).

High Altitude Application
The equipment operates at altitudes from 0…1000 m (0…3300 ft) above sea
level, without derating. For applications above 1000 m (3300 ft), the
maximum current and basic impulse levels (BIL) of the controllers shall be
derated, and vacuum contactors may be compensated for operation at the
specified altitude (see publication 1500-SR020).

1. To access the low voltage compartment, use a screwdriver and turn both
of the 1/4-turn fasteners, which are located on the low voltage door, 90°
in a counterclockwise direction.
2. The door is now released and will swing open.
3. Reverse the procedure to secure the doors.

ATTENTION: Use suitable personal protective equipment (PPE) per local
codes or regulations. Failure to do so may result in severe burns, injury, or
death. Refer to the standards such as NFPA 70E, Standard for Electrical Safety
in the Workplace and CSA Z462, Workplace Electrical Safety Standard for

Opening the Medium Voltage Doors
The medium voltage doors are identified as MV in Figure 4.
Figure 4 - MV Door Locking Bolt and Isolation Switch Location
Refer to Access to the Power Bus on page 18 for the procedure to open the
swing-out low voltage panel behind the low voltage door (for standard cabinet
only).
1. Electrically open the contactor by pressing the STOP button on the
starter or at the remote control location.
2. Move the isolation switch handle to the OFF position.
3. Unscrew the door locking bolts for both medium voltage doors.
ATTENTION: Medium voltage components may be located behind the
swing-out low voltage panel (standard cabinets only). Complete the power
lockout procedure (See Power Lock-out Procedure on page 49) before
attempting to open the swing-out low voltage panel. Failure to do so may
result in severe burns, injury, or death.
ATTENTION: Complete the Power Lockout procedure (See Power Lock-out
Procedure on page 49) before beginning anyservice procedures to the unit.
Failure to do so may result in severe burns, injury, or death.
IMPORTANT The medium voltage doors have their own isolation switch handle and
interlocking safeguards. The top MV door must be opened before the lower
MV door can be opened.

4. The doors are now released and will swing open to the left.
5. Reverse the procedure to close the door
Anchoring Place the controller in the desired installation location. The floor must be flat
and level. The mounting surface for the equipment must be flat and within
±1 mm per meter. Installing metal shims is an acceptable method of
compensating for mounting surfaces that are out of tolerance. Mounting
surfaces that are not flat may inhibit proper set-up and operation of the latches
and interlocks. Use four M12 (1/2 in.) floor mounting bolts to securely fasten
the controller to the mounting surface. See Figure 6 as an example of the
location of the mounting holes in the cabinet.
IMPORTANT Verify that the swing-out low voltage panel is in its original position
before attempting to close the MV door. When closing the medium
voltage door, confirm all doorlocking bolts on the right side of the
MV door are in place and tightened until the door isflush with the
flange. Donotovertightenthebolts.Ifthe door is not securely

procedures to the unit. Failure to do so may result in severe burns,

TIP Refer to Dimension Drawing provided with order documentation for
additional details that are related to cabinet floor plan.
IMPORTANT Pre-determined cabinets have been designed for Uniform Building Code
(UBC) seismic zone 1, 2A, 2B, 3 and 4, and IBC (International Building Code)
seismic activity without overturning or lateral movement, provided they are
securely mounted according to UBC, IBC, and local building codes. Thiscan
include concrete paddesign, steel floor design, and thesizing of cabinet
anchors. Concrete floor cutouts must not be next to floor anchor bolts and
must be sized to seismic load. Consult the factory if floor mounting must be
reviewed by an accredited engineer. 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 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 (refer to Anchoring on
page 15).
2. When joining NEMA/EEMAC Type 12 sections, apply a continuous
3 mm (1/8 in.) wide bead of silicon sealer around the perimeter of one
section.
3. Remove the side bus access covers if applicable.
4. Position the right section against the left section. Verify that the surface
is level.
5. Secure the sections together using the 1/4-20 self-tapping screws.
Thread the screw through the 7 mm (0.281 in.) clearance hole to the
corresponding 6 mm (0.219 in.) pilot hole. To access the front clearance
holes of the left-side cabinet, open the medium voltage 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 Line Cables
and Power Bus on page 20 or Front Access – Bottom Incoming Line
Cables on page 23.
6. Secure the right section to the floor using M12 (1/2 in.) floor mounting
bolts (refer to Anchoring on page 15).
TIP Joining hardware can be found in a package that ismounted to the front of
the shipping skid. See publication MV-QS050 for level floor surface
requirements.
IMPORTANT For arc resistant cabinets, see Chapter 3 for special instructions.
ATTENTION: The mounting surface for the equipment must be flat and
within ±1 mm per meter. Installing metal shims is an acceptable method of
compensating for mounting surfaces that are out oftolerance. Mounting
surfaces that are not flat may inhibit proper set-up and operation of the
latches and interlocks.

Access to the Power Bus
Rear access is the preferred access method for attaching line cables and for
making bus splice connections. However, these procedures can be done with
front-only access. Front access requires more time and disassembly of the
equipment to complete this procedure.
Rear Access
1. Remove the hardware securing the center rear bus access cover
(Figure 8).
2. Remove the center rear bus access cover.
3. Once the rear bus cover is removed, you will see the three busbars
(Figure 9).

ATTENTION: This procedure requirescontact with medium voltage
components. To avoid shock hazards, lock out incoming power before
working on the equipment (See Power Lock-out Procedure on page 49).
Verify with a hotstick or appropriate voltage measuring device that all
circuits are voltage free. Failure to do so may result in severe burns, injury, or
death.

Side Access
A side bus access cover is on each side of the controller.
1. Remove the hardware from the appropriate side bus access cover.
2. Remove the side bus access cover.
3. Once the side bus access cover is removed, you will see the three busbars.

Complete the Power Lockout Procedure (See Power Lock-out Procedure on
page 49) for both medium voltage power cells and the power bus.
1. Open the low voltage cell door (refer to Opening the Low Voltage
Doors on page 13).
2. Open the medium voltage cell doors (refer to Opening the Medium
Voltage Doors on page 14).
3. Remove the three door hinge pins on each medium voltage
compartment door.
4. With two people, carefully set the doors carefully aside.
5. Remove two self-tapping screws from the upper low voltage panel
upright supports (Figure 11).
