replaced.
Cabinet Replacement
ä
To replace cabinets, refer to “Cabinet Floor Mounting” on Page 5-21
.
AC Power and Grounding Requirements
The system requires a solid earth ground for proper operation and safety. The AC power cord(s) 
already contains a conductor for the “third wire ground” provided by the commercial power outlet. 
An insulated conductor must connect the frame ground terminal on the Base Cabinet (or the 
bottom Expansion Cabinet) to a cold water pipe or the building ground.
Notes
lThe “third wire ground” (“A” in Figure 5-28) must be dedicated. The conductor connected to 
the frame ground must comply with the general rules for grounding contained in Article 250 of 
the National Electrical Code, NFPA 70, but must not depend on the cord and plug of the 
system. 
WARNING! Failure to provide ground may be a safety hazard or lead to confusing trouble 
symptoms and, in extreme cases, system failure.

AC Power and Grounding Requirements
Strata DK I&M 5/995-29
DK424 Installation
AC Power and Third Wire Ground Test
Test each “third wire ground” separately for continuity by either measuring the resistance between 
the third prong terminal (earth ground) and a metal cold water pipe (maximum: 1 ohm) or by using 
a commercially available earth ground indicator. If neither procedure is possible, perform the 
following procedure.
ä
To test each “third wire ground” for continuity
1. Obtain suitable voltmeter, and set it for a possible reading of up to 250VAC.
2. Connect the meter probes between the two main AC voltage terminals (white and black wires) 
on the wall outlet. The reading obtained should be between 100 ~ 125VAC.
3. Move one of the meter probes to the third terminal (green wire ground, point A in Figure 3-
19). Either the same reading or a reading of zero volts should be obtained. 
4. If the reading is zero volts, leave one probe on the ground terminal and move the other probe 
to the second voltage terminal.
CAUTION!If a reading of zero volts is obtained on both voltage terminals (white wire to 
green wire, black wire to green wire), the outlet is not properly grounded. Omit 
Steps 5 and 6, and proceed directly to Step 7.
5. If a reading of zero volts on one terminal and a reading of 100 ~ 125VAC on the other terminal 
is obtained, remove both probes from the outlet.
6.Set the meter to the “OHMS/Rx1” scale. Place one probe on the ground terminal, and the other 
probe on the terminal that produced a reading of zero volts. The reading should be less than 
one ohm.
CAUTION!If the reading is more than one ohm, then the outlet is not adequately grounded. 
If the above tests show the outlet AC voltage is not in range or is not properly 
grounded, the condition should be corrected (per Article 250 of the National 
Electrical Code) by a qualified electrician before the system is connected.
äTo test the frame ground conductor for continuity 
1. Disconnect the AC plug(s) of the system to make sure that the separate earth ground paths are 
separated.
2. With a suitable volt/ohm meter, perform a reading between points “A” and “B” shown in 
Figures 5-28, 5-21 and 5-22. Verify that the readings do not exceed the figures listed below. If 
they do, the condition must be corrected by a qualified electrician before the system is 
connected.
WARNING! Hazardous voltages that may cause death or injury are exposed during the 
following test. Use great care when working with AC power line voltage.

AC Power Cabling Installation
5-30Strata DK I&M    5/99
A to B: 1 volt maximum then A to B: 1 ohm maximum
Intercabinet Ground 
Connect intercabinet ground wires (supplied with each cabinet) between cabinets in systems with 
two or more cabinets (Figures 5-21 and 5-22).
AC Power Cabling Installation
The system requires an input power source of 50/60 cycles, 115VAC ± 10 VAC, and up to 17.5 
amps AC to operate. AC power cabling requirements vary, depending on the method of cabinet 
installation and the number of cabinets. Refer “Summary of Electrical/Environmental 
Characteristics” on Page 5-4 for electrical power requirements.
Some floor-mounted configurations and all wall-mounted configurations require AC outlets, 
which must be dedicated to system use, fused, and grounded. To avoid accidental turn off, do not 
configure the outlet with an ON/OFF switch.
AC Power for One or Two Cabinets (Wall Mount)
Refer to the following instructions to install AC power cabling to floor or wall-mounted systems 
with just one or two cabinets:
1. Make sure all power supply (RPSU280) switches are in the OFF position.
2. If two cabinets are installed and local electrical code allows only one AC power cord from the 
system, install the RPSB2 in the bottom cabinet per Figures 5-19 and 5-20.
3. For AC power cords that will be plugged directly into a wall outlet: Undo the tie wrap that 
keeps the cord coiled. Plug female end of the cord into the power supply, and plug the male 
end into the wall outlet.
4. For AC power cords that will be plugged into power strips: Do not undo the tie wrap that 
keeps the cord coiled. Plug female end of the cord into the power supply, and plug the male 
end into the RPSB power strip. Plug the power strip power cord into a wall outlet (see Figure 
5-9). 
NotePower Supply testing procedures are provided in Chapter 12 – Fault Finding, which 
should be referred to if it is suspected that the power supply does not work properly.
