3 Installation

3.1 Installation Quick Check List - Indoor MCC.s Only
Receiving
 Inspect package for damage.
 After unpacking, inspect equipment for damage in transit.
 If damaged or incomplete, substantiate claims against
shipper with identification of parts, description of damage,
and photographs.
Handling
 Simplify handling by leaving equipment on shipping skid.
 Use the lifting angle provided for moving the equipment.
 Take care to use the proper method of moving a motor
control center.
Storage
 Store in a clean, dry space at moderate temperature.
 Cover with a canvas or heavy-duty plastic cover.
 If storage area is cool or damp, cover equipment completely
and heat to prevent condensation.
Location Selection
 Flat and level floor.
 Overhead clearance.
 Accessibility front and rear (if required).
 Protection from splash and drip, dust, and heat.
 Space for future expansion.
 If bottom conduit entry is used, conduit should be in place
and stubbed up before equipment is installed.
Installation Method
 Grout into the foundation.
 Weld channel sills to steel leveling plates.
 Imbedded anchor bolts in the floor.
Field Assembly
(Instruction sheet included with shipment)
 Remove hardware and horizontal bus connecting links from
shipping splits.
 Install first shipping split.
 Remove end cover plates of structures to be joined (if
required).
 Carefully align second split with first. Bolt structures
together at four corners and middle, front, and rear.
 Remove horizontal wireway barrier to expose horizontal
bus.
 Connect horizontal buses with bus links. Torque bolts to
20 ft.-lbs.
 Grommet top and bottom horizontal wireways.
 Install heater coils. (Check selection against motor
nameplate data.)
 Install fuses.
Conduit Entry at Top
 Remove top plates from structure.
 Cut conduit entry holes in top plates.
 Reinstall top plates.
 Install conduits
Note: This checklist is not exhaustive and particular applications my require further procedures.

Incoming Line Connections
 Choose the shortest, most direct route from remote mains.
 If cables cannot be directly routed to terminals, provide
adequate space for clamping the cables.
 Torque incoming lines to main lugs only at 85 ft.-lbs.
 Torque all incoming connections to main circuit breakers
and fusible disconnects as per the breaker or disconnect
manufacturer's recommendations. The torque requirements
are found on a label located on the disconnecting device.
Outgoing Power and Control Wiring
 Disengage plug-in unit stabs from vertical bus. Connect
control and power wiring to units.
 Use stranded wire.
 Leave enough slack to permit partial withdrawal of unit to
test position for maintenance.
 Pull wiring between units through vertical and horizontal
wireway securing wires in the vertical wireway with wire
from wire ties provided.
 Route wiring between sections through the top or bottom
horizontal wireways.
 Reinsert plug-in units to engage stabs.
Pre-Operation Checks
 Test insulation resistance of all circuits with the control
center as ground.
 Remove restraining devices from contactors and shunts
from current transformers. Make sure that all parts of
magnetic devices operate freely.
 Check electrical interlocks for proper contact operation.
 Make sure that each motor is connected to its proper
starter.
 Check all heater elements for proper installation.
 Check all timers for proper time interval setting and contact
operation.
 Check fusible disconnect starters for proper fuse size.
 Clean the control center. Rid it of all extraneous material.
Use a vacuum cleaner, not compressed air.
 Check all connections for mechanical and electrical
tightness
 Close all access plates and doors.
Energizing Motor Control Centers
 Make sure all unit disconnect handles and control
center mains are turned to OFF.
 Turn on remote mains.
 Turn on motor control center main circuit breakers or fusible
disconnects.
 Turn on unit disconnect handles one by one.
 Jog motors to check for proper rotation.
 Adjust ETI Breakers.
