Connecting the iMCC Cabling
System
Units within iMCCs are connected at the factory. The cable used varies with
the network type. The pin outs for the various networks are shown in Table 9:
Network Cabling Factory supplied network cabling is installed in accordance with UL 845
procedures and practices, and routed in the bottom horizontal wireway.
In order to make direct connections to Class 2 or Class CM systems, install
Class 2 or Class CM wiring so that it is separated from power conductors
either by a barrier or a minimum space of 0.25 in. (6 mm). Route power
conductors in the top horizontal wireway for maximum separation.
External network cabling must comply with Class 2 or Class CM practices
under the provisions of NEC Articles 725 and 800.
Cables Between Shipping Splits Connect the trunk line cables between shipping splits by aligning the
keyways and plugging the male end of the trunk cable to the female end of
the next trunk cable. Screw the coupling ring until it is hand-tight. Repeat
this process until all shipping splits are connected.
Load Cables It is recommended to route all load cables in the top horizontal wireway to
keep them isolated from the communications cabling. If you route the load
cables in the bottom horizontal wireway, make sure to maintain a 0.25-in.
(6 mm) distance between the communications cabling and all other cabling.
Communication Networks There are three primary ways to connect communication networks: via
bridges/repeaters, programmable logic controllers (PLCs), or a direct cable
connection. Follow the applicable instructions below to make the cabling
connections for your Model 6 iMCC.
Bridges/Repeaters If the PLC is not in the local area of the MCC, you will typically need to use a
bridge/repeater to connect the communication network.
Terminating Resistors In order for the communication network to operate properly, terminating
resistors are required on each end of the network. If your iMCC is shipped
with a bridge, repeater, and/or PLC, external terminal blocks (MCT485) are
included with shipment.
Direct Cable Connection
Follow the steps below to connect a cable directly to the network via the
iMCC network cable.
1. Determine which end (male or female) of the iMCC network you will
attach to your cable.
2. Strip back the communication cabling insulation.
3. Based on the network, use the pin outs given in the table at left.

HAZARD OF EQUIPMENT DAMAGE
Do not use excessive force when making iMCC
cabling connections. Connections are keyed to
ensure that pins are properly aligned.
Failure to follow this instruction can result
in equipment damage.
