(1) Use 12 to 28 AWG wire for the power, input (except for range 26),
external control, and comparison output connectors.
(2) Tighten the screws for the power, input (except for range 26),
external control, and comparison output connectors to a torque of
0.5 to 0.6 Nm.
(3) Use 16 to 28 AWG wire for the analog output connector.
Tighten the screws of analog output connector to a torque of 0.22
to 0.25 Nm.
