直流輸出端
直流輸出電纜連接的顏色編碼為紅色-+24V和黑色-0V。這些應連接到適當的直流輸入卡終端。
建議將交流至直流電源裝置連接使用裝置后部提供的接地螺柱連接至系統接地。
為了額外的電氣安全，剩余電流裝置（RCD）類型：電源處應使用斷路器。
將交流電源升級為直流電源單位
警告AC至DC電源單元內存在高電壓。斷開交流電源至少五分鐘取下頂蓋并執行任何操作前的分鐘維護或升級操作。18.1總則有兩種類型的交流到直流電源裝置，一種是8路50W和16路50W。8路裝置可升級為100W，并配備增加第二個50W開關模式模塊。16路單元可升級至100W、150W或200W，增加50W開關模式模塊，如有必要，配備50W子單元。
18.2 8路和16路交直流電源裝置升級至100W
要將8路或16路交流至直流電源單元升級為：100W按如下步驟進行：
（1） 卸下并固定電源頂蓋的螺釘供應裝置，然后提起蓋子。
（2） 切斷并拆下固定未使用空調的固定帶，以及至子單元機箱的直流連接電纜。
（3） 在要添加到50W子單元的50W開關模式模塊上，從下側拆下并丟棄四個填料螺釘但是，保留模塊的長螺母和墊圈。
（4） 在要添加到50W子單元的50W開關模式模塊上，確保印刷電路板下的墊片：正確定位。（5） 插入模塊，方向與已安裝的方向相同模塊，進入50W子單元內的空位置，以及
使用步驟（3）中保留的墊圈和長螺母固定。
（6） 連接50W子單元第二交流輸入和24V直流輸出連接交流輸入端子CN1和直流輸出的電纜接頭
終端CN2分別處于新增的50W切換模式
模塊如下所示：
（7） 重新安裝頂蓋。
18.3 16路交流至直流電源裝置升級至150W或200W
DC Output
The dc output cable connections are colour coded RED - +24V and
BLACK - 0V. These should be connected to the appropriate DC
Input Card terminals.
It is recommended that the AC to DC Power Supply Unit is connected
to the system earth using the earth stud provided at the rear of the unit.
For additional electrical safety a Residual Current Device (RCD) type
circuit breaker should be used at the supply source.
UPGRADING THE AC TO DC POWER SUPPLY
UNITS
WARNING
High voltages exist within the AC to DC Power Supply Unit.
Disconnect from the ac supply for a period of at least five
minutes before removing the top cover and carrying out any
maintenance or upgrade operation.
18.1 General
There are two types of AC to DC Power Supply Unit, an 8-Way 50W
and 16-Way 50W. The 8-way unit may be upgraded to 100W with the
addition of a second 50W Switched Mode Module. The 16-way unit
may be upgraded to 100W, 150W or 200W with the addition of 50W
Switched Mode Module(s) and if necessary a 50W Sub Unit.
18.2 8-Way and 16-Way AC to DC Power Supply Unit Upgrade
to 100W
To upgrade the 8-Way or 16-Way AC to DC Power Supply Units to
100W proceed as follows:
(1) Remove and retain the screws securing the top cover of the power
supply unit and lift the cover clear.
(2) Cut and remove the retaining straps that secure the unused ac and
dc connecting cables to the sub-unit chassis.
(3) On the 50W Switched Mode Module to be added to the 50W SubUnit, remove and discard the four packing screws from the underside
of the module, however, retain the long nuts and washers.
(4) On the 50W Switched Mode Module to be added to the 50W SubUnit, ensure that the spacers under the printed circuit board are
correctly located.(5) Insert the module, with the same orientation as the already fitted
module, into the vacant position inside the 50W Sub Unit and
secure using the washers and long nuts retained in Step (3).
(6) Connect the 50W Sub Unit second ac input and 24V dc output
cable connectors to the ac input terminal CN1 and dc output
terminal CN2 respectively on the added 50W Switched Mode
Module as shown below:
(7) Refit the top cover.
