I have bought HOMAGE 1000VA UPS and have to question to ask. I hope some one would be able to help me.
A sticker at the UPS says in WARNING at point NO 3
"The neutral wires of AC output connector and AC input connector should be LINKED through a jumper."
pleae refer image below.
Would some one explain what does that mean and is it necessry?
other question is that I am already using UPS. Electrician wired the UPS into circuit by giving PHASE by UPS and used NEUTRAL from exisating home wiring to save his time of installation. Now while switching to HOMAGE ups will I have to again rewire by taking both PHASE & NEUTRAL from UPS to Appliances?
If you have a circuit breaker in your house then it means there should be no load between the circuit breaker and homage input and between homage output and circuit breaker.
Normally, you get the input to your homage from a electric socket and run the output wires from homage back to the circuit breaker from where it goes to your desired rooms. If you have done this then the input and output neutrals should be common as both come from the same circuit breaker. If you put something in between the homage output and circuit breaker then the input and output neutrals are not common anymore.
You should always get a professional electrician to install UPS etc. I had mine done by an electrician. They charge you Rs. 500 but it is worth it.
I hope I answered your question. Let me know if you still have problems.
