Note:
1. Do not connect multiple water circulation pumps directly to each output (OUT1, OUT2, and OUT3). In such a case, connect
them via (a) relay(s).
2. Do not connect water circulation pumps to both TBO.1 1-2 and CNP1 at the same time.
3. Connect an appropriate surge absorber to OUT10 (TBO.3 1-2) depending on the load at site.
4. Stranded wire should be processed with insulation-covered bar terminal (DIN46228-4 standard compatible type).
5. Use the same thing as the Signal input wire for OUTA1 wiring.
