Is there polarity for connecting electrical wiring to the DC type of the VP300/500/700 series?
-
When the lead wires of the valve are identified by the colors red and black, the red color is the polar (positive) and the black color is the non-polar (negative). Please connect + (positive) lead wire to terminal 1 and - (negative) lead wire to terminal 2 in the DIN terminal type or any other terminal type without lead wires.
In addition to the non-polar type such as VP342-5DU1-01A products, we recommend you connect the lead wire + (positive) to terminal 1 and the lead wire - (negative) to terminal 2 in case of changing to the polar type.
