Notes:
1. Use a minimum wire gauge of 22 AWG.
2. Use a maximum of 80 ohms per pair of wires for
the network connections.
3. Use shielded twisted pair for network connections.
4. Terminate the shield ONLY at the MMB
enclosure.
5. For MMB-1/-2 Style 4, use a 120 Ohm, 1/4W,
5% EOLR, P/N 140-820150, in positions 1 and
2 on plug J8.
For MMB-3 Style 4, use Res EOL Assembly, 120

6. This configuration is power limited to NFPA
70 according to NEC 760.
7. The RCC-3/-3C/-3F/-3FC MUST have an
earth ground connected to the chassis. Wire
shield or conduit is not an acceptable ground.
Use any available unused, unpainted stud on
the MMB for chassis grounding.
8. Refer to Wiring Specification for MXL, MXL-IQ
and MXLV Systems, P/N 315-092772 revision
6 or higher, for additional wiring information.
