在外殼入口點(diǎn)將地線（P.E.或保護(hù)接地）與電源線分開。為盡量減少外殼內(nèi)的地線長度，將接地參考點(diǎn)定位在工廠電源入口附近。

Mounting Instructions Rack Mounting 1. Select and prepare an appropriate mounting location according to the Mounting Considerations on page 10. 2. Install the unit in the rack (with drive access facing outward) using the standard rack-mounting hardware. 3. Attach one end of the power cord to the power receptacle and the other end to a properly grounded 115/230 VAC, 50-60 Hz outlet. 4. Turn on the power. The system will boot up to the installed operating system. 5. Install application software via a floppy drive or CD-ROM. Figure 2–19. Installing Rack Mounting Hardware Rack Mounting with Slide Rails 1. Place the unit on a solid work surface and disconnect all cables and cords from the unit. 2. Attach the provided Xycom slide rails (ordered separately by order number 1600–RMS) to the unit (see Figure 2–20). 3. Install the unit securely in the rack with standard rack-mounting hardware so that the drive access door faces outward. 4. Torque the rail-mounting screws to 35 in/lbs. 5. Reconnect all cables and cords. 15 1600 Series with Pentium 4 Chapter 2 – Installation Figure 2–20. Installing Optional Slide Rails System Power It is always a good idea to use isolation transformers on the incoming AC power line to the 1600. An isolation transformer is especially desirable in cases where heavy equipment is likely to introduce noise onto the AC line. The isolation transformer can also serve as a step-down transformer to reduce the incoming line voltage to a desired level. The transformer should have a sufficient power rating (units of volt-amperes) to supply the load adequately. Proper grounding is essential to all safe electrical installations. Refer to the relevant Federal, State, Provincial, and local electric codes that provide data such as the size and types of conductors, color codes and connections necessary for safe grounding of electrical components. The code specifies that a grounding path must be permanent (no solder), continuous, and able to safely conduct the ground-fault current in the system with minimal impedance (minimum wire required is 18 AWG, 1 mm). Observe the following practices:
Separate ground wires (P.E. or Protective Earth) from power wires at the point of entry to the enclosure. To minimize the ground wire length within the enclosure, locate the ground reference point near the point of entry for the plant power supply.
All electrical racks or chassis and machine elements should be Earth Grounded in installations where high levels of electrical noise are expected. Ground the chassis with a ground rod or attach to a nearby Earth structure such as a steel support beam. Each different apparatus should be connected to a single Earth Ground point in a “star” configuration with low impedance cable. Scrape away paint and other nonconductive material from the area where a chassis makes contact with the enclosure. In addition to the ground connection made through the mounting bolt or stud, use a one-inch metal braid or size #8 AWG wire to connect between each chassis and the enclosure at the mounting bolt or stud.
