3.7.1 RS-485 Connection
The pin definition for the RS-485 terminal block is shown in Table 3-3. – Pins 1 and 2 provide a 12VDC / 0.5A bus for use with accessories. – Pins 3 and 5 are both connected to the DATA+ input. – Pins 4 and 6 are both connected to the DATA – input. These connections allow easy daisy-chaining of multiple inverters. A 120ohm bus termination resistor and associated control switch are located on the communication board (Table 3-4). Different RS-485 connection scenarios require different set up for the 120ohm bus termination resistor. · When several inverters are cascaded (i.e., “daisy-chained”) only the last inverter
in the chain must have its bus termination resistor switched ON (Figure 3-25). · If the length of any RS-485 bus is greater than 610m, the use of Belden 3105A
cable (or eq.) is recommended to insure communication quality.
ATTENTION
– In order to have good transfer quality, twisted-pair wire is recommended to be used as communication cable.
