* If control switch is closed when power is applied, relay will immediately energize. A 50 millisecond minimum switch closure is required. IMPORTANT: A dry circuit switch is recommended. A
** Note: Input polarity for DC operation. For most reliable operation on AC, connect high side to “+” and low side to “–”.
