Note
If only two conductors each for power and return
are used, contacts J, K, L, and M must be used.
Contacts J, K, L, and M will accommodate up to
16 AWG single conductor wiring; all other
contacts will accommodate 20 AWG single
conductor wiring.
6.9.2 MTX5000 System TNC Connector Interface
CAUTION
To avoid potential problems, existing wiring
harnesses must be carefully examined for
evidence of damage, corrosion, or broken
wire strands.
Any damage detected must be repaired
before a new MTX5000 system is placed
into service.
If your MTX5000 IDU and ODU contain the TNC RFU 1 and
RFU 2 connectors, the IDU and ODU can be connected using an
existing harness,
ODU End The existing power connector at the ODU end will
plug in directly to your ODU.
IDU End At the IDU end, the harness connector will not plug
directly into your IDU. You must cut off the terminal block at the
IDU end and must connect the wiring harness to the Weidmuller
connector supplied with the IDU. Verify the new connections are
as shown in Figure 6-7 on page 6-13. Connections for ODU 2
(RFU 2) are identical to ODU 1 (RFU 1).
The actual number of wires in your harness, and their gauges,
may differ from the standard harness. To provide enough current
to the RFU, MRC recommends the minimum power and ground
connections specified in “Cabling Requirements” on page 6-9
