3000/3010 System Manual
To connect power to a Fan Module:
1. Determine which pair of fuses/circuit breakers are to supply power to the fan
module.
2. Remove the fuses/turn off circuit breakers from the A and B slots in the fuse and
alarm panel for the pair determined in step 1.
3. Cut four lengths of 16 or 18 gauge wire to reach from the terminals on the fuse and
alarm panel to the power terminal strip on the Fan Module. Be sure to include
enough length to allow for tying the wire neatly to the frame as specified by CO
SOP. Wire color should differentiate between -48 VDC supply and return,
according to CO SOP.
4. Using a crimping tool, connect an appropriate lug to each end of the four wires.
5. Using a screwdriver appropriate for the fuse and alarm panel terminals and a #1
Phillips head screwdriver for the Fan Module terminals, connect the -48 VDC A
CO supply to the -48 VDC A fan module terminal. Connect the -48 VDC A CO
return to the -48 VDC RET A fan module terminal. Connect the -48 VDC B CO
supply to the -48 VDC B fan module terminal. Connect the -48 VDC B CO return
to the -48 VDC RET B fan nodule terminal.
6. Install fan filter.
1.4.6 Apply Power and Check Voltage, Remove Power
Before proceeding further, ensure that power has been correctly applied to the shelf.
The proper voltage to the Total Access 3000/3010 shelf and fan unit is -48 VDC, with
an operating range of -42 VDC to -56 VDC.
CAUTION
Installing fuses in the fuse alarm panel at this stage will provide power to the
shelf and fans. All three fans on the fan module will begin to rotate and there
will be power to pins on the backplane and inside the shelf. Exercise caution
to avoid electric shock.
1. Install 20 Amp fuses in the slots in the fuse and alarm panel that service the Total
Access 3000/3010 shelf or turn on the 20 Amp circuit breaker that powers the
shelf.
2. Using a voltmeter, place the common (normally black) lead on the TS1 -48 VDC
RET terminal and the DC volts (normally red) lead on the TS1 -48 VDC PRI
terminal. The reading should be in the operating range of -42 VDC to -56 VDC,
with a nominal value of -48 VDC. Note the “-” polarity.
3. Using a voltmeter, repeat step 2, using the TS2 -48 VDC RET terminal and the
TS2 -48 VDC SEC terminal.
4. Remove the fuses/turn off circuit breakers from the fuse and alarm panel slots
powering the Total Access 3000/3010 shelf.
