I have a water pump (Hydor L20 1/2") that uses a a plug but want to change that so it can plug onto the back of a Criticool PowerPlant II Pump Relay Card.
I have a water pump (Hydor L20 1/2") that uses a a plug but want to change that so it can plug onto the back of a Criticool PowerPlant II Pump Relay Card.
I use this card with an Eheim pump and I just cut the mains plug off the end of the pump power cable leaving enough cable to reach the card probably about 6 - 8 inches, and then fit the three copper wires, live (brown), earth (yellow/green) and neutral (blue) into the the screw down block on the end of the card. I am about to do it with a Hydor L30 and notice there is only a blue and brown cable but it should connect up the same way.
I really like the switch on the outside of the pci plate which lets you run the pump without turning on the PC - good for testing the system before startup.
The wires are inserted into the grey connector in ur picture which is on the very edge of the card which is furthest away from the switch. My connector is labelled "HOT" (brown wire), "GND" (optional green/yellow wire) and "NEU" (blue wire). I unscrew the tiny screws put the wires inside the connector then screw back down to hold down the wires.
