Chapter 1 General Information
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).
WARNING: Do not store the equipment outside.

Door Opening Procedure Opening the Low Voltage Doors
Low voltage doors are identified as LV in Figure 3.
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.
Figure 3 - Standard Cabinet
Refer to Access to the Power Bus on page 17 for the procedure to open the
swing-out low voltage panel behind the low voltage door.
IMPORTANT For information on the installation site preparation, see
publication MV-QS050.
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 safety guidance when working in and
around electrical equipment.

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 17 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 locking 3/8-1.75 bolts for both MV doors.
The doors are now released and will swing open to the left.
4. Reverse the procedure to close the door
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 any service
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.

Chapter 2 Installation – Standard Enclosure
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 door locking
bolts on the right side of the MV door are in place and
tightened until the door is flush with the flange. Do not
overtighten the bolts. If the door is not securely fastened, it
is not be possible to move the isolation switch handle to the
ON position.
ATTENTION: Complete the Power Lock-out procedure
(See Power Lock-out Procedure on page 49) before beginning
any service procedures to the unit. Failure to do so may result
in severe burns, injury or death.
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. This 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. 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.

Seismic Applications
•For installation on concrete – the minimum depth and radius of the
concrete which support the cabinet anchors is dependent on seismic
loads. See important information above.
•For installation on a metal structure – the metal plate depth and cabinet
anchoring method is dependent on seismic loads.

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.

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 (12 lb•ft
[15 N•m]). 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 19 or Front Access – Bottom Incoming
Line Cables on page 22.
6. Secure the right section to the floor using M12 (1/2 in.) floor mounting
bolts (refer to Anchoring on page 15).

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.
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 of
tolerance. Mounting surfaces that are not flat may inhibit proper set-
up and operation of the latches and interlocks.

ATTENTION: This procedure requires contact 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 hot stick or appropriate voltage measuring
device that all circuits are voltage free. Failure to do so may result in
severe burns, injury, or death.
