When the wires are wired to adjacent terminals use ring terminals and insu-
late the wires.
Note:
1. Do not connect multiple water circulation pumps directly to each output (OUT1). 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. Stranded wire should be processed with insulation-covered bar terminal (DIN46228-4
standard compatible type).
