Figure 11: RS-485 Wiring

Notes:

1. Termination resistors are optional and values depend on the cable length and characteristic im-

pedance. Consult the cable manufacturer for recommendations.

2. Refer to RS-232 to RS-485 Converter documentation for further details.

3. Use shielded cable, twisted-pairs plus ground. Connect ground shield only at one location.

WARNING

Observe all safety regulations. Electrical wiring should be performed

in accordance with all agency requirements and applicable national,

state, and local codes to prevent damage to the meter and ensure

personnel safety.
