JDB Solutions Posted May 10, 2017 Share Posted May 10, 2017 See image here i have the following on the power supply: red= AC24V black= AC24V yellow&green= earth On my power supply it is PTZ 3.0 Amp 24V Supply I have a black 2 core cable from the transformer so do i just connect these to the red and black or has the red and black to go together and then the earth on the other core of the transformer? it isnt very clear so i just want to be sure? I look forward to hearing from you soon!

ElecTech Posted May 10, 2017 Share Posted May 10, 2017 (edited) Are you in the industry or DIY? *answer to question - connect one black wire to RED, one to BLACK. Earth goes to a similar earth.

JDB Solutions Posted May 10, 2017 Author Share Posted May 10, 2017 I tried this and it didn't seem to work the IR's on the dome did not light up i have covered up the photocell on the dome however it didn't light up Any ideas? I thought possibly the RED & BLACK if they are AC24V pay both be positive and the other earth may be the earth/ negative on the twin core?
