Select a surge absorber that satisfies the following conditions.
Control Output 2
• For 900-TC8 & 900-TC16: Output 2 is applied from terminals 11 and
12 or 14 and 15 with the 900-TC16, and from pins 14 and 15 with the
900-TC8. The following diagrams show the available outputs and their
equal internal circuits.
