安裝I/O模塊執(zhí)行以下操作：
?插入新I/O模塊之前，請(qǐng)檢查其是否損壞。
?I/O模塊側(cè)面的識(shí)別標(biāo)簽將被隱藏安裝模塊時(shí)。因此，在安裝前記下模塊的位置和標(biāo)簽上顯示的詳細(xì)信息。安裝
1.檢查終端組件上的編碼銷釘，確保將插座安裝在新I/O模塊的后部。
2.將I/O模塊放在T9300 I/O基座裝置的定位銷上。
確保模塊夾緊螺釘頭上的槽垂直且然后將模塊推入原位，直到模塊連接器完全匹配帶有I/O基本單元和終端組件連接器。
3.鎖定螺釘需要順時(shí)針轉(zhuǎn)動(dòng)四分之一圈才能鎖定。使用廣泛的（9mm）平頭螺絲刀，用于鎖定夾緊螺釘。鎖緊螺釘用作電源聯(lián)鎖裝置，當(dāng)通電，否則模塊將無(wú)法配置。
I/O模塊啟動(dòng)過(guò)程當(dāng)模塊安裝到在線與將模塊安裝到離線，具有處理器模塊，但未安裝I/O模塊。
安裝新終端裝配要安裝新的終端組件，請(qǐng)執(zhí)行以下操作。
卸下I/O模塊
卸下使用終端組件的每個(gè)I/O模塊：
1.定位模塊前部的鎖緊螺釘頭。使用于逆時(shí)針旋轉(zhuǎn)螺釘?shù)膶挘? mm）一字螺絲刀四分之一圈，使槽垂直。
2.抓住模塊頂部和底部，將其從控制器。
斷開并拆除現(xiàn)有終端組件
1.記錄TA接線板上每條導(dǎo)線的標(biāo)識(shí)和位置，然后斷開每根導(dǎo)線。
2.按下終端組件下方的固定凸舌（多個(gè)凸舌對(duì)于雙模塊和三模塊冗余版本），然后將終端組件向下。
3.取出終端組件。安裝并接線新終端組件
1.將終端組件背面的固定夾插入I/O基本單元上的插槽。
?將終端組件壓到底座上，然后滑動(dòng)盡可能地組裝。?確保每個(gè)固定卡舌卡在印刷電路板上以進(jìn)行設(shè)置終端組件就位。
2.將接線連接到螺釘接線板。應(yīng)用最小值擰緊扭矩為0.5 Nm（0.37 ft.lb.）至端子螺釘。
3.插入I/O模塊（請(qǐng)參閱I/O模塊安裝程序）。
Install I/O Modules
Do the following: ? Before inserting a new I/O module, examine it for damage. ? The identification labels on the sides of the I/O module will be hidden when the module is installed. Therefore before installation write down the location of the module and the details shown on the label.Installation 1. Examine the coding pegs on the termination assembly and make sure that they fit the sockets on the rear of the new I/O module. 2. Place the I/O module on to the dowel pins on the T9300 I/O base unit. Make sure the slot on the head of the module clamp screw is vertical and then push the module home until the module connectors are fully mated with the I/O base unit and termination assembly connectors. 3. The locking screw requires a quarter turn clockwise to lock. Use a broad (9mm) flat blade screwdriver to lock the clamp screw. The locking screw acts as a power interlock device and must be in the locked position when power is applied otherwise the module will not be configured. I/O Module Start-up Process The start-up sequence is different when a module is installed into an on-line system that is running compared to installing the module into a system that is off-line and has processor modules but no I/O modules installed.
Install a New Termination Assembly
To install a new termination assembly, do the following. Remove the I/O Module(s) Remove each I/O module that uses the termination assembly: 1. Locate the head of the locking screw on the front of the module. Use a broad (9 mm) flat blade screwdriver to turn the screw counterclockwise a quarter turn so the slot is vertical. 2. Grasp the module at the top and bottom and pull it away from the controller. Disconnect and Remove the Existing Termination Assembly 1. Record the identity and location of each wire at the TA terminal block, then disconnect each wire. 2. Depress the retaining tab below the termination assembly (multiple tabs for dual and triple modular redundant versions) and then pull the termination assembly downwards. 3. Lift out the termination assembly.Fit and Wire the New Termination Assembly 1. Insert the retaining clip on the back of the termination assembly into the slot on the I/O base unit. ? Press the termination assembly onto the base unit and then slide the assembly up as far as it will go.? Make sure each retaining tab clips over the printed circuit board to set the termination assembly in position. 2. Connect the wiring to the screw terminal blocks. Apply a minimum tightening torque of 0.5 Nm (0.37 ft. lb.) to the terminal screws. 3. Insert the I/O modules (refer to the I/O module installation procedure).
