Chapter 4 Removal and Replacement Procedures
Removing and Installing the DC-Input Power Supplies
Step 12
Remove the warning flags and cautionary tape from the source DC mains and switch the source DC on.
Step 13
Verify the power supply operation by checking that the power supply front panel LEDs are in the
following states:
•
INPUT 1 OK LED—If you have source DC cables attached to the VE-1 pair of power supply inputs,
verify that the LED is green, otherwise the LED should not be lit.
•
INPUT 2 OK LED—If you have source DC cables attached to the VE-2 pair of power supply inputs,
verify that the LED is green, otherwise the LED should not be lit.
•
FAN OK LED is green.
•
OUTPUT FAIL LED is not lit.
If the LEDs indicate a power problem, see the
“Identifying Startup Problems” section on page E-3
.
Removing and Installing a 4000 W DC-Input Power Supply
This section covers the power supply removal and installation procedures for the 4000 W DC-input
power supply and is divided into the following topics:
•
Required Tools, page 4-37
•
Removing a 4000 W DC-Input Power Supply, page 4-38
•
Installing a 4000 W DC-Input Power Supply, page 4-40
Note
For proper 4000 W DC-input redundant power configurations, all of the source DC for one 4000 W
DC-input power supply must come from the same battery system (A feed); all of the source DC for the
other 4000 W DC-input power supply must come from another battery system (B feed).
The 4000 W DC-input power supply can operate at either 2700 W or at 4000 W. If you want to operate
the power supply at 2700 W, you need to connect two pairs of source DC cables to the VE-1 and the
VE-2 posts on the power supply terminal block. If you want to operate the power supply at 4000 W, you
need to connect a third pair of source DC cables to the VE-3 terminal block posts.
Note
For multiple DC-input power supplies, each DC input must be protected by a dedicated circuit breaker
or a fuse. The circuit breaker or fuse must be sized according to the power supply input rating and the
local or national electrical code requirements.
Figure 4-26
shows the features on a 4000 W DC-input power supply. Use the illustration for reference
as you remove and install the power supply.
