APC Backup Pro 1500G

I recently purchased this UPS and have connected it to a 3-phase line in series with my room's 1.5 ton window ac. Both the loads are supplied by a 32A MCB. The normal voltage rating of the power connection is 220-230 V. But the moment I switch on my AC, the voltage rating drops to 210-215 V. Will it affect the UPS in anyway? 

Let me rephrase the question. The back UPS is supporting my desktop only. But the input power to the UPS is in series with the AC power connection. The AC is supported by a normal relay and AVR. But since the power line is same, the input voltage to the UPS drops the moment AC is switched on. Will the reduced Input Voltage affect the UPS life or performance in anyway is the question I wanted an answer to. 🙂

Manish,

A Back-UPS is not designed to be used in this type of configuration. It is not support.

As for how this will affect the UPS. We cannot be sure. This configuration has never been tested.
