Step 3

Set the rear circuit breaker to the Off/

0

position (if it is not

already off).

Step 4

Remove the cover from the plant battery terminal strip.

Step 5

Connect the

−48 VDC A and −48 VDC B terminals of the CPX to the

−48 VDC A and B outputs of the power source using two 14 AWG
(or larger), stranded or solid wires terminated in #10 size
compression ring lugs (Caltronics #RT-117, or equivalents).

Step 6

Connect the Return A and Return B terminals of the CPX to the A
(+) and B (+) terminals of the power source as in step 5.

Step 7

Run the

−48V power and battery return wires across the back of

each CPX shelf and along the side of the equipment rack, or use the
optional Cable Management Assembly.

Note

Be sure that all grounding connection surfaces are free
and clear of contaminants.

Caution

Make proper polarity connections. Damage may occur to
the circuitry when powered up if polarity is reversed.

Note

If you use 14 AWG wire, be sure that the plant battery
power distribution point is no more than 40 feet from
the CPX. Use a larger gauge wire if the power source is
further away.

Note

The RTN A and RTN B terminals are also connected
together inside the CPX enclosure.
