Installation and Operation
Configuration internal to the enclosure is required on
RC Series power supplies prior to installation into a rack .
Ensure all power is disconnected before performing this
initial configuration .
1.3.1 Removing the Top Cover of the Enclosure
Use the following steps to remove the top cover of the rack-
mount enclosure and gain access to the configurable settings .
(Figure 2)
1 . Lay the enclosure flat on its bottom surface
2 . Remove and retain the six philips head screws from
the top cover
3 . Remove the top cover and set it aside in a safe location
When configuration is complete, reverse the removal pro-
cedure to replace the cover .

1.3.2 Configuring for a 230VAC Input Voltage
The RC series is factory set for a 120VAC input . If the RC is to
be used with a 230VAC input, jumper JP1 must be cut on ALL
FPO power supplies internal to the RC . (Figures 3 and 4) . See
the FPO manual for more information .
i
Failure to cut JP1 on both supplies when connecting to a
230VAC input will damage the system and void the warranty .
1.3.3 Setting the Output Voltage
The RC Series Rackmount series will contain one internal
FPO power supply . Models with a "B" in the model number
will also contain a B100 Secondary Power Supply board .
In single voltage systems, the voltage may be set on the
FPO power supply to 12 or 24VDC . After removing the top
cover, set the output voltage of the FPO power supply by
moving SW1 to either 12V or 24V (See #3 in Figure 3) .
Systems with a B100 installed must leave the FPO set for
24VDC . The B100 should be left as set for a 12V output .
See the FPO and B100 manuals for more information on
setting the output voltage .
1.3.4 Enabling or Disabling Battery Presence Detection
The FPO power supply may be set to detect a missing bat-
tery set . To enable battery presence detection, place the
BATDET jumper ON . To disable battery presence detection,
remove the BATDET jumper, or place it on only one pin .
(See #2 in Figure 3)
1.3.5 Enabling or Disabling Earth Ground Detection
The FPO power supply is able to detect earth ground faults .
To enable earth ground fault detection, place the EARTH
GND DET jumper ON . To disable earth ground fault detec-
tion, remove the EARTH GND DET jumper or place it on only
one pin . (See #1 in Figure 3)
i
NOTE
Only one device in a system should have earth
ground fault detection enabled or conflicts may occur .
1.3.6 Changing the Operation of the Fault Contact Output
From the factory, RC Series Rackmount supplies are
shipped with a normally open fault contact operation (relay
contact closed until a fault occurs) .
This operation may be switched to a normally closed con-
tact (relay contact open until a fault occurs) by moving a
wire on each fault contact .
To switch from the default NO fault contact to a NC contact,
locate the fault output terminal strip on the FPO power sup-
ply . Identify the contact you want to change (SYS FLT or AC
FLT), loosen the terminal, remove the wire from the NO ter-
minal, move it to the NC terminal, and tighten the terminal .
1.3.7 Changing the FAI Operation
The DC2 output may be set to either power up when an FAI
is received or to drop power when an FAI is received by
changing the position of the DC2 fuse on the FPO board .
This has no effect on the distributed outputs, only the bulk
DC2 Output .
• DC2 NO Position - DC2 output has no voltage until a
valid FAI input signal is received .
• DC2 NC Position - DC2 output has voltage present in
the normal state . This voltage goes away when a valid
FAI input signal is received .
