IC693PCM311數(shù)字燃機(jī)模塊
要安裝端子蓋：
1.如圖所示定位蓋。注意四個(gè)鉤子接線片和以太網(wǎng)電纜間隙斷路器。
2.在兩個(gè)小切口處輕輕擠壓蓋在蓋子邊緣，并完全插入四個(gè)鉤子后面板插槽中的蓋舌。
3.讓蓋側(cè)放松。把蓋子拉直直到它卡入位。在蓋邊緣將接合上的兩個(gè)對(duì)齊凸舌后面板。
需要時(shí)，以太網(wǎng)電纜應(yīng)退出通過(guò)蓋中的大切口。
要卸下蓋子：
1.在兩個(gè)切口處輕輕擠壓蓋
在蓋邊緣中（距離蓋的頂部）并向上推蓋。
2.從后面板上拉出蓋。安裝或取下蓋子：
擠壓雙方~1/16"清除對(duì)齊標(biāo)簽。
以太網(wǎng)電纜斷路器。
圖8-1直接入口連接器，蓋的安裝和拆卸安裝
1.將連接器的可拆卸部分與固定部分對(duì)齊。
2.將可拆卸部分壓到固定部分上。
3.擰緊兩個(gè)固定螺釘。不要過(guò)緊。檢查導(dǎo)線和部件是否保持連接安全地。
4.如上圖所示安裝蓋。
蓋和連接器的拆卸和安裝，側(cè)面進(jìn)入刪除：
1.輕輕壓縮連接器蓋的U形擠壓件，以釋放連接器蓋的凸耳，從而拆下連接器蓋。
蓋可以用兩個(gè)螺釘固定，如下所述。蓋子如圖8-5所示。
2.如有必要，斷開(kāi)、松開(kāi)或解開(kāi)連接至待拆卸連接器的導(dǎo)線。一定要去導(dǎo)線是否有足夠的松弛度，以便拆卸接頭。
3.抓住連接器凸舌，并從殼體中直接拉出。拉向中心的輕微偏壓
連接器插座通常易于拆卸。參見(jiàn)圖8-3。注意不要應(yīng)力或損壞連接的導(dǎo)線和組件。
To Install Terminal Cover:
1. Orient the cover as shown. Note the four hooked
tabs and Ethernet cable clearance cutout.
2. Squeeze the cover slightly at the two small cutouts
in the cover edges and fully insert the four hooked
cover tabs in the rear panel slots.
3. Allow cover sides to relax. Pull the cover straight
down until it snaps into place. The cutouts in the
cover edges will engage two alignment tabs on
the rear panel.
Where needed, the Ethernet cable should exit
through the large cutout in the cover.
To Remove Cover:
1. Squeeze the cover slightly at the two cutouts
in the cover edges (about 2" down from the
top of the cover) and push cover upward.
2. Pull cover out from rear panel.
To install or
remove cover:
squeeze
both sides
~1/16"
to clear
alignment
tabs.
Ethernet cable cutout.
FIGURE 8-1 Direct Entry Connectors, Cover Installation and Removal
Installation
1. Align the removable portion of the connector with the fixed portion.
2. Press the removable portion onto the fixed portion.
3. Tighten the two captive screws. Do not over tighten. Check that wires and components remain connected
securely.
4. Install the cover as shown in the above figure.
COVER AND CONNECTOR REMOVAL AND INSTALLATION, SIDE ENTRY
Removal:
1. Remove the connector cover by slightly compressing the cover’s U-shaped extrusion to free the cover’s tabs.
The cover may be secured by two screws, as described below. The cover is shown in Figure 8-5.
2. As necessary, disconnect, unclamp, or unbundle wires connected to the connector to be removed. Be sure there
is sufficient slack in the wiring for connector removal.
3. Grasp the connector tab and pull straight out from the case. A slight bias on the pull toward the center of the
Connector Socket will often ease removal. See Figure 8-3. Be careful not to stress or damage connected wires
and components.
