* Note: Input polarity for DC operation. For most reliable operation on AC, connect high side

to “+” and low side to “–”.

** Important: A dry circuit switch is recommended. A “dry circuit” switch is one rated to

reliably switch currents of less than 50mA. Use of a switch rated for other

than dry circuit may result in failure of the time delay relay to function properly.
