Wiring Guidelines
Electrical Connections - Power, I/O, and LIL or Modbus network connections to a basic controller are completed
through removable connectors with terminals H, N, and 3-26. When the controller includes an I/O Expander board,
connectors with terminals 27-52 are also used. A case with direct entry connectors has an Ethernet connector for
use when an Ethernet board is included and the MPU Controller board firmware is V2.4 or later. Connector
locations are shown in Figures 8-5 and 8-6. Individual terminals functions are also identified in Table 8.1.
Connectors - Power terminals are identified by a letter: Hot and Neutral. The ground connection is made to a green
case/safety ground screw located between connectors. Signal I/O terminals are identified by a number: 3 through
52. A connector terminal will accept the following wire(s).
? one 14-22 AWG (2.1-0.38 mm2
)
? two 16 AWG (1.3 mm2
)
? three 18 AWG (0.96 mm2
)
Wire Size Recommendations:
? signal wiring - 18 AWG (0.96 mm2
)
? power wiring - 18 AWG (0.96 mm2
)
Wire Stripping Recommendations:
? connector terminal wiring - 1/4" (6 mm) to 5/16" (8 mm)
? green ground screw wiring - 1/8" (10 mm) to 1/2" (13 mm)
Be careful not to nick the conductor or cut away strands. Can cause death or injury
? Remove power from all wires and terminals before working on equipment.
? In potentially hazardous atmosphere, remove power from equipment before
connecting or disconnecting power, signal, or other circuit.
? Observe all pertinent regulations regarding installation in hazardous area. Wire Selection - Stranded wire is recommended for most connections, however, solid wire is typically used for
thermocouple extension wire. Carefully select wire size, conductor material, and insulation. Some selection
considerations are:
? current and voltage to be carried
? total length of each wire run
? whether wire will be bundled or run singly
? indoor or outdoor installation
? temperature extremes (Use supply wires suitable for 5°C (10°F) above ambient temperature.)
? exposure to sunlight
? vibration
? types of contaminates
Station Common, Terminal 6 - Within the Moore 353, station common is connected to:
? the two-wire power supply common (COM, terminal 6)
? digital output common (DOUTC, terminal 9)
? all analog input and analog output commons (e.g., AIN1C, terminal 21)
Station common is isolated from case/safety ground. It should be connected to the user’s instrument bus common at
only one point. Digital input commons are isolated from the station common and case/safety ground.
Connector Terminal and Ground Screw Torque Specifications:
? connector terminals - 5 in. lbs (0.56 N m)
? green case/safety ground screw - 20 in. lbs (2.26 N m)
