3.2 INSTALLATION
Immediately upon receipt, the equipment should be unpacked and examined for any damage sustained in tran-
sit. If damage resulting from rough handling is evident, file a damage claim at once with the transportation com-
pany and promptly notify the nearest GE Sales Office.
If the equipment is not to be installed immediately, it should be stored indoors in a location that is dry and pro-
tected from dust, metallic chips, and severe atmospheric conditions.
The LPS-D should be installed in a clean and dry location, free from dust and excessive vibration, and well
lighted to facilitate inspection and testing.
The LPS-D case has been designed for standard rack mounting. The case is three Rack Units (3 RU) high.
Figure 3–2: FRONT AND REAR VIEW on page 3–2 shows the outline and mounting dimensions.
External connections are made according to the elementary diagrams, Figure 1–22: ELEMENTARY DIAGRAM

nal A18 tied to station ground, as shown in the elementary diagrams, Figure 1–22: ELEMEN-
