Before You Begin

Follow this procedure before you begin installing your unit.

1. Remove all packaging material from the unit.

2. Read the unit installation instructions.

3. Manually exercise all switches, control auxiliary switches, circuit breakers,

their respective operators, unit interlocks, trip mechanisms (test by
pushing the ‘Push to Trip’ button), and any other operating mechanisms to
verify proper operation.

Plug-in units with horizontal operating handles cannot be used in sections
with series letters A...D. In sections with series letters E...J, these units can be
plugged into only the top 5.5 space factors. There is no vertical bus in the
bottom 0.5 space factor.

Sections with series letters E…J require retrofit kit, catalog number 2100H-R1,
for 0.5 space factor, or catalog number 2100H-R2 for 1.0 or larger space factor.
See CENTERLINE 2100 Motor Control Centers Retrofitting Units with Horizontal
Operating Handles into Series E…J Sections, publication 2100-IN065

ATT EN TI ON : When you install units for CENTERLINE 2100 Motor Control Centers
(MCC) with ArcShield™ baffles, you must make sure that you are installing a unit
that has the same arc resistance rating as the MCC in which it is being installed.
Units that are not rated for 100 ms arc duration must not be installed in a
section that is rated for 100 ms arc duration. If the incorrect unit is installed, the
arc resistant rating does not apply. The 0.5 space factor units and doors are not
available in ArcShield units with 100 ms arc duration designs. Do not use 0.5
space factor units in 100 ms arc duration rated MCC sections.

Recommended Tools

Ground the Unit

We recommend having a screwdriver available for installation.

You need a 5/16 in. and a 3/8 in. socket wrench for installing ArcShield units.

Follow this procedure to ground the unit.

ATT EN TI ON : If this unit is installed in a series E…J section without a vertical
plug-in ground bus, it is necessary to either install a vertical plug-in ground bus
kit, catalog number 2100H-GS1, 2100H-79U, or 2100H-79UT, or ground the unit
to the structure ground bus.
Follow NFPA 70E safety guidelines when working on energized equipment.
To avoid personal injury and damage to the unit, be certain that the unit
operating handle is in the OFF/O position before proceeding.

1. Determine the minimum size grounding-conductor required from the
following table.

2. To ground the unit to the structure ground bus, attach a unit grounding
conductor between the unit chassis and the structure ground bus.

The size of the grounding connector is based on the unit current rating.

Follow this procedure to install the support pan.

The unit support pans above (or wireway pan for the topmost units in a
section) and below the unit compartment must be in place before installing
the unit.

ATT EN TI ON : All covers and doors must be in place before you apply power to
the MCC. If units are removed, they must be replaced with the appropriate items
such as units, doors, and unit support pans.

ATT EN TI ON : If power sources are connected to the motor control center, use
extreme caution when you insert units. All buses and the line sides of the
inserted units are energized, and contact with these parts can cause injury and
death.
Follow NFPA 70E safety guidelines when working on energized equipment.

1. For ArcShield sections with 100 ms arc duration rating, remove the
vertical wireway baffle and set aside for installation later.

2. If present, remove the isolation barrier from the vertical-wireway wall
cutout.

3. De-energize the unit in the space below where the unit support pan is to be
installed.

4. Open the unit door above and below where the unit support pan is to be
installed.

5. Place the unit support pan into the unit space, hold the right side of the
support pan approximately 4 in. (102 mm) higher than the left side.

6. Place the left front corner of the support pan into the slot on the front of
the left sidesheet flange.

7. Place the left rear corner of the support pan into the slot of the left
sidesheet C-channel.

8. Lower the right edge of the unit support pan into the vertical-wireway wall
cutout, and press down firmly.

Install the Unit

Follow this procedure to install the unit.

ATT EN TI ON : De-energize all units before installing or removing.
When you install or remove MCC units, when possible, de-energize, lockout,
and tag-out all sources of power to the MCC. If the MCC units are installed or
removed with power applied to the main power bus, follow established
electrical safety work practices. See the NFPA 70E Standard for Electrical Safety
in the Workplace publication.
Review your company safety lockout and tag-out procedure.
If power sources are connected to the motor control center, use extreme caution
when you insert units. All buses and the line sides of the inserted units are
energized, and contact with these parts can cause injury or death.
All covers and doors must be in place before you apply power to the MCC. If
units are removed, they must be replaced with the appropriate items such as
units, doors, and unit support pans.

ATT EN TI ON : Plug-in MCC units can be heavy or awkward to handle. Use an

TIP

IMPORTANT

Reposition your hands as necessary to properly support the unit while you
are installing the unit into the MCC.

2. Place the unit on the bottom unit-support pan, slide the unit interlock to
the left, and push the unit into the section until it is in the desired position,
then release the unit interlock.

3. Install other cables or devices.

There are two positions available (normal operating and disconnected). In the
normal operating position, the power and ground stabs are connected to their
respective busses. In the disconnected position, the unit is partially removed
from the MCC and the intermediate slot in the interlock plate is in line with the
bushing located in the unit support pan. When the unit is locked in this
position, the unit power and ground stabs are disengaged. This position can be
used to prevent insertion of a unit into the MCC.

ATT EN TI ON : For proper operation of the latch/interlock mechanism, a style 3
unit-support pan with bushing must be used below the unit. If the unit support
pan with bushing is not used, the unit could be removed under load, which can
result in injury or death.

For the CENTERLINE 2100 MCC units with swing-out door latches, it is
necessary to rotate the movable portion of the latch bracket to a vertical
orientation to avoid interference when installing the unit.

Be sure to comply with the National Electric Code 6.7 ft (2 m) unit handle-to­floor height limitation, as identified in NEC 2005 Article 404.8(A) and UL
standard 845, for units in the topmost location of a vertical section.

A unit operating-handle extender kit, catalog number 2100H-NE1, is available
for any handles higher than 6.7 ft (2 m) off the ground.

wireway baffle.

Install the Door

Follow these procedures to install the door.

1. Position the door over the unit opening while holding the right side of the
door slightly toward you and push in the left side until it is flush with the
front of the structure.

Latches can require a flat-head screwdriver to open and close.

If this unit is installed in a series E...J section, it is necessary to install a longer
latch assembly to latch into the wireway opening. The latch is included in the
plug-in unit retrofit kit, catalog number 2100H-R1, or 2100H-R2.

When properly latched, the slots on the arc resistant latches are vertical and
the latch springs are compressed. The spacing of the spring coils is
decreased.
