(The non-polar type can be used with the connections made either way.) . Since voltage specifications other than standard 24 and 12 VDC do not have diodes for polarity protection, be careful not to make errors in the polarity. . When wiring is done at the factory, positive (+) is red and negative (.) is black. Operating Principle �� With power saving circuit Power consumption is decreased by 1/4 by reducing the wattage required to hold the valve in an energized state. (Effective energizing time is over 62 ms at 24 VDC.)

For the standard type, connect + to 1 and . to 3 for Type W according to polarity, while + to 4 and . to 3 for Type WA. . Please be careful not to reverse the polarity, since a diode to prevent the reversed current is not provided for DC voltages other than 24 and 12 VDC. .
