An external resistance of 1 100,000,000 operations at rated load. megohm is required to obtain the max- **Initial Dielectric Strength** — imum time for all ranges. To determine Between Terminals and Mounting — the actual resistance needed to obtain 3,000VAC rms. the required time delay, use the followBetween Input and Output — ing formula: 1,500VAC rms.
**Transient Protection** —
Non-repetitive transients of the following magnitudes will not cause spurious operation of affect function and accuracy. Line voltage with high inductive voltage noise could affect timer performance. Adding transorb or MOV at noise source is recommended.
