Starter Features
Provide information regarding any special features required for the starter kit.
Indicate if these features are different from the motor control features in the
existing, complete power cell.
Recommended Torque
Values
When reinstalling components or when reassembling the cabinet, tighten the
following bolt sizes to the specified torque values:
Environmental Conditions The controller must accept nominal plant power of 2400V, 3300V, 4200V,
4800V, 5500V, 6600V, 6900V (+5/-15%), or 7200 (+0/-15%), 3 phase
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% (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).

ATTENTION: Medium voltage components are located behind the
swing-out low voltage panel (standard cabinets only). Complete the
Power Lock-out procedure (see Power Lock-out Procedure on page 53)
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 (see Power Lock-
out Procedure on page 53) before beginning any service procedures to
the unit. Failure to do so may result in severe burns, injury or death.

Refer to Access to the Power Bus on page 16 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.

Handles
IMPORTANT Each medium voltage door has its own isolation switch handle and
interlocking safeguards. Upper and lower power cells are separated
by an isolation barrier.
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 (see Power Lock-
out Procedure on page 53) before beginning any service procedures to
the unit. Failure to do so may result in severe burns, injury or death.

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.
Figure 5 - Cabinet Floor Plan
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.
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.

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 14).
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.
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– Access to Power Bus on
page 18.
6. Secure the right section to the floor using M12 (1/2 in.) floor mounting
bolts (refer to Anchoring on page 14).

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 53).
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.
