Configuration and Usage
This section describes the final configuration as well as op-
eration details for the RA and RD series power supplies .
2 .1 Removing the Faceplate of the Enclosure
Use the following steps to remove the faceplate of the rack-
mount enclosure and gain access to the front boards .
1 . Remove and retain the five philips head 6-32 screws
from the faceplate . DO NOT remove the four 10-32
screws securing the enclosure to the rack .
2 . Carefully remove the faceplate and set it aside in a
safe location
When configuration is complete, reverse the removal pro-
cedure to replace the cover, taking care to align the LEDs
with the holes in the faceplate .

2 .2 Configuring the Outputs
Each output zone is configurable for one of two selections
which vary by model type . Selections are made by moving the
zone's corresponding jumper (marked as B1 and B2 on the PC
Board) . See Figure 5 .
RA Series
Each output is configurable for 24VAC or 28VAC
• B1 (Left)
24VAC Output
• B2 (Righ)
28VAC Output
RD Series - Single Supply Models
Each output is configurable for continuous or FAI con-
trolled . To set the operation of the FAI controlled outputs,
see Section 1 .3 .6 .
• B1 (Left)
Continuous Output (No FAI control)
• B2 (Right)
FAI Controlled Output
RD Series - Dual Supply Models
Each output is configurable for either internal power supply .
FPO#1 is the power supply on the left when looking from
the front and FPO#2 is the power supply on the right .
FAI control is provided on any distributed outputs set for
FPO#2 and the DC2 terminals of both FPO power supplies .
• B1 (Left)
FPO #1
• B2 (Right)
FPO #2

2 .3 Disabling Faults
Sometimes it is desirable to disable fuse fault detection for
individual zones . This allows removal of the fuse for spe-
cific unused zones or zones with unfinished wiring .
Faults can be disabled via the block of switches on the top
right of each front board (See Figure 2 .2) . Note that the
color of this switch block may vary . Switch numbers cor-
respond with zone numbers of the board (Switch 1 disables
faults for Zone 1, etc .) . Switch settings are as follows:
• ON
Fault Detection Enabled
• OFF
Fault Detection Disabled
2 .4 Status LEDs
Each front board has nine LEDs (See Figure 5) . The eight
green LEDs give the voltage availability of the associated
zone . The yellow LED will light if a fault condition is detected .
