Paradyne CPX-1000 Be sure that all grounding connection surfaces are free, Clear of contaminants

3. Installing the CPX-1000 1000-A2-GN22-00

	Note
	Be sure that all grounding connection surfaces are free
	and clear of contaminants.
Step 3	Set the rear circuit breaker to the Off/0 position (if it is not
	already off).
	Caution
	Make proper polarity connections. Damage may occur to
	the circuitry when powered up if polarity is reversed.
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).
	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.
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.
	Note
	The RTN A and RTN B terminals are also connected
	together inside the CPX enclosure.
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.
