Spectrian Proprietary -- See notice on first page
2.4.3.2 Connect DC Input Power Cables
The MCPS2000 power connection can be made using a pair of wires for each RF
module, or via a single bussed connection. The DC input voltage cabling must be
terminated by crimped lugs and sized to the correct wire gauge to accommodate the
wire length and the DC current requirements of the MCPS2000 in accordance with
local building codes and industry practice. Refer to paragraph 2.1.2.3 for the
recommended power supply circuit and wire sizing for each option.
☛ WARNING: Do not perform DC lead installation with energized leads. Ensure
that the DC power supply is OFF for all installation activities!
16. Locate the positive and negative terminals on the customer-provided DC power
source, and verify polarity with a VOM.
17. Locate the power supply lugs at the top of the rear of the shelf subassembly.
The four #10 lugs for the per-RF-Module connection option, the single pair of
¼” lugs are for the bussed power option. Determine which set of lugs will be
used for this installation.
18. Measure the distance and routing between the power source and the MCPS2000
DC lugs.
19. For each power connection being made, cut equal lengths of wire for power and
return. Strip and connect each wire to the appropriate power connection.
☛ Verify the polarity of each supply wire prior to connecting them to the shelf
subassembly. A reversed-polarity connection will severely damage the MCPS2000
and will void the product warranty.
20. Crimp the appropriate terminal lugs onto each power supply wire.
21. Attach one positive supply wire and one return wire to each of the four sets the
power supply lugs at the top of the rear of the shelf subassembly. Tighten the
attachment nuts firmly.
2.4.3.3 Connect RF Output and Input Cables
The MCPS2000 has one female type-N amplified RF output for connection to a
customer-supplied coaxial cable terminated with a male connector, and one female
SMA RF input for connection to an operator-supplied input cable terminated with a
male SMA connector.
☛ Important: The integrity of RF cabling is critical to the electrical performance of
the MCPS2000. Ensure connectors are properly built, free of debris, and clean.
☛ WARNING: Do not perform RF cable installation with DC power supplied to the
MCPS2000. Ensure that the input DC power supply is OFF before handling RF
cables.
☛ Important: The Output cable must be connected before connecting the Input
cable.
22. Locate the male N-type RF output connector on the end of the coaxial cable
attached to the output load. Inspect the connector and clean if necessary; fix any
problems with the cable or connector before proceeding.
23. Locate the female connector labeled “RF OUTPUT” on the MCPS2000.
