Chapter 1 General Information
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% (non-condensing).
Higher ambient temperature conditions are supported with factory assistance.
The equipment shall be capable of being stored 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 having 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 shall operate 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_-EN-P).
WARNING: The equipment should never be stored outside.

Door Opening Procedure Opening the Low Voltage Doors
Low voltage doors are identified as LV in Figure 3.
1. To access the compartments for standard cabinets – use a flat-head
screwdriver and turn both of the 1/4-turn fasteners at least 90° in a
counterclockwise direction.
2. The door is now released and will swing open.
3. Reverse the procedure to secure the doors.

IMPORTANT
For information on the installation site preparation, see General Handling
Procedures for MV Products, Publication MV-QS050_-EN-P.
ATTENTION: Use suitable personal protective equipment (PPE) per local codes
or regulations. Failure to do so may result in severe burns, injury or death.

Opening the Medium Voltage Doors
Medium voltage doors are identified as MV in Figure 4.
Figure 4 - Access to Medium Voltage Compartments
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 door locking bolts for medium voltage door.
4. The door is now released and will swing open.
ATTENTION: Medium voltage components are located behind the swing-out
low voltage panel (standard cabinets only). Complete the Power Lock-out
procedure (refer to Power Lock-out Procedure on page 57 of Chapter 5) 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 Lock-out procedure (refer to Power Lock-out
Procedure on page 57 of Chapter 5) before beginning any service procedures to
the unit. Failure to do so may result in severe burns, injury or death.

5. Reverse the procedure to close the door.
Anchoring Place the controller in the desired installation location. Use M12 (1/2 in.) floor
mounting bolts to securely fasten the controller to the mounting surface. See
Figure 5 as an example of the location of the mounting holes in the cabinet.
IMPORTANT
Ensure 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,
ensure 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 will not be possible to move the
isolation switch handle to the ON position.
ATTENTION: Complete the Power Lock-out procedure (refer to Power Lock-out
Procedure on page 57 of Chapter 5) before beginning any service procedures to
the unit. Failure to do so may result in severe burns, injury or death.
TIP
Refer to Dimension Drawing provided with order documentation for additional
details 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 adjacent to floor anchor bolts and must be
sized to seismic load. Consult 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.

NOTES FOR SEISMIC APPLICATIONS
• For installations on concrete – the minimum depth and radius of
concrete supporting the cabinet anchors is dependent on seismic loads.
Refer to important information above.
• For installations on a metal structure – the metal plate depth and cabinet
anchoring method is dependent on seismic loads.
Joining Sections
1. Position the left side of the section on a level surface and secure the section
in place with 12 mm (1/2 in. [M12]) floor mounting bolts (refer
to Anchoring on page 15).
2. When joining NEMA Type 12, apply a continuous 3 mm (1/8 in.) wide
bead of silicone 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. Ensure that the surface is
level.
Line cable conduit opening.
Load cable conduit opening for bottom compartment.
Load cable conduit opening for top compartment.
Control wire conduit opening. Each opening provides
access to top and bottom compartments.
Mounting holes for 1/2 in. (M12) anchor bolts.
Mounting holes for 1/2 in. (M12) anchor bolts (required for
seismic applications only).
Minimum distance to concrete floor cut-out required for
seismic applications.
1.00 (25) x 3.00 (76) non removable sill channels.

TIP
Joining hardware can be found in a package mounted on the front of the
shipping skid. Refer to publication MV-QS050_-EN-P for level floor surface
requirements.

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– Access to Power Bus on page 19.
6. Secure the right section to the floor using M12 (1/2 in.) floor mounting
bolts (refer to Anchoring on page 15).

ATTENTION: This procedure requires contact with medium voltage
components. To avoid shock hazards, lock out incoming power before working
on the equipment (refer to Power Lock-out Procedure on page 57 of Chapter 5).
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.

3. Once the rear bus cover is removed, you will see the three power bus bars
and the ground bus bar (see Figure 8).

Side Access
A side bus access cover is located on each side of the controller.
1. Remove the hardware from the appropriate side bus access cover (see
Figure 7).
2. Remove the side bus access cover.
3. Once the side bus access cover is removed, you will see the three power bus
bars and the ground bus (see Figure 9).

1. Complete the Power Lock-out Procedure (refer to Power Lock-out
Procedure on page 57 of Chapter 5) for both medium voltage power cells
and the power bus.
2. Open the doors and remove the hinge pins.
ATTENTION: To avoid shock hazards, lock out incoming power (refer to Power
Lock-out Procedure on page 57 of Chapter 5) before working on the equipment.
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.

3. Open the low voltage cell doors (refer to Opening the Low Voltage Doors
on page 13).
4. Disconnect the control wiring harness from the wire plug at the lower left
side of the contactor.
5. Remove the two self-tapping screws from the center vertical channel (see
Figure 10).
6. Pull on the center vertical channel to swing out the low voltage panel.
