Note: Option 1 can only be used if the chain contains an SI-RFA-TS connector (the SI-RFA-TK cannot be
connected to an SSA-ISD-TCA).
Figure 7. Option 2: Replace the terminator with a power supply. The OSSD1 and OSSD2 wires at power supply #2 must be connected to +24 V DC. If
available, set the power supplies for parallel output.
