Hello,
Is there a Bypass Mode option available on APC Smart-UPS 750RM? [Such an option is available on Smart UPS 8000]. Please help me.
Thanks in advance,

if the battery fails, it should illuminate the replace battery LED. it will do this about a month or two before the battery will most likely completely fail. it will still output power to your load and it will chirp once every five hours to tell you to replace the battery. if you still dont replace it the UPS will try its best to stay online and output power but if there is a power outage and there is no good battery or the battery cannot support the load, the UPS will turn off.

Alex,

While there isn't a Bypass switch option for this UPS, you can effectively get the same function by using an automatic transfer switch.
[AP7750|http://www.apc.com/resource/include/techspec_index.cfm?base_sku=AP7750] for example.
Connect one input (primary) to the UPS, connect the other input to utility. The ATS will automatically bypass the UPS if it fails or is taken off-line. You also have the option of manually forcing a bypass.
The ATS has a web interface and notification options, handy for out of the way closets or other locations that don't get regular visual inspections.

you can also look into a wrap around service bypass panel, such as [this one|http://www.apc.com/resource/include/techspec_index.cfm?base_sku=SBP3000RM2U] or [this one|http://www.apc.com/resource/include/techspec_index.cfm?base_sku=SBP3000]

with the automatic transfer switch, it is sort of like a bypass where basically if one AC input (the UPS) fails, it will switch to an alternative (secondary) AC source. ideally each source should be its own circuit for full redundancy.

Thanks for the reply. One more question: If battery fails on Smart UPS 750RM, does it automatically bypass and draw power from wall outlet or it shuts down?
