小心不要劃傷導線或割斷絞線。可能導致死亡或受傷
?在設備上工作之前,從所有電線和端子上斷開電源。
?在潛在危險的環境中,在連接或斷開電源、信號或其他電路。
?遵守關于危險區域安裝的所有相關規定。導線選擇-大多數連接建議使用絞合導線,但通常使用實心導線
熱電偶延長線。仔細選擇導線尺寸、導體材料和絕緣。
一些選擇考慮因素包括:
?要承載的電流和電壓
?每條電線的總長度
?電線是捆扎還是單獨敷設
?室內或室外安裝
?極端溫度(使用適用于高于環境溫度5°C(10°F)的電源線。)
?暴露在陽光下
?振動
?污染物類型站公用,終端6-在摩爾353內,站公用連接到:
?雙線電源共用(COM,端子6)
?數字輸出公用(DOUTC,端子9)
?所有模擬輸入和模擬輸出共用(例如,AIN1C,端子21)
站公用線與外殼/安全接地隔離。應將其連接到用戶的儀表總線,共有:
只有一點。數字輸入共用線與站公用線和外殼/安全接地隔離。
連接器端子和接地螺釘扭矩規格:
?連接器端子-5英寸。磅(0.56牛頓米)
?綠色外殼/安全接地螺釘-20英寸。磅(2.26牛頓米)
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)
