Heschen Single Phase AC/DC Solid State Relay SSR-60DA 3-32 VDC/480VAC 60A 50-60Hz

Instructions are conflicting.

This unit looks to be very well made but it is let down by a total lack of any technical data or wiring circuit supplied by the seller or the manufacturer! I searched the net and found the Heschen site which had a brief circuit on how it is wired up, however the DC input (trigger) is shown on one picture with the pos and neg leads reversed to them on the other pictures. I guess then unit will be destroyed if this DC voltage is connected incorrectly. So I can only give a 2 star review with a need for correction to the wiring scheme.
