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 flat-head screwdriver and
turn both of the 1/4-turn fasteners, 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.

ATT EN TI ON : Medium voltage components may be located behind the swing-
out low voltage panel (standard cabinets only). Complete the power lockout
procedure (refer to Power Lock-out Procedure

attempting to open the swing-out low voltage panel. Failure to do so may result
in severe burns, injury or death.
ATT EN TI ON : Complete the Power Lockout procedure (refer to Power Lock-out
Procedure on page 41 of Chapter 5) before beginning any service procedures to

Opening the Medium Voltage Doors
Medium voltage door is identified as MV in Figure 3.
The medium voltage door has its own isolation switch handle and interlocking
safeguards.
Refer toAccess to the Power Bus
on page 7 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 the medium voltage door.
4. The door is now released and will swing open.
5. Reverse the procedure to close the door
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 41 of Chapter 5) 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. The floor must be flat and
level. Use four 12 mm (1/2 in. [M12]) floor mounting bolts to securely fasten the
controller to the mounting surface. See Figure 4
the mounting holes in the cabinet.
Refer to Dimension Drawing provided with order documentation for additional
details related to cabinet floor plan.
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.
