Alpha Technologies Micro, Micro XL, Micro XL3 UPS - Manual (Page 28)

017-237-B0 Rev A 26
5.6 UATS and (UGTS) Option
The ATS (automatic transfer switch) and the GTS (generator transfer switch) are two separate optional add-on
switching units for the Alpha Micro family of UPS. The ATS provides power and/or bypass capacity (automatic
or manual) so the operator may disconnect the Alpha Micro from line power for easy removal and servicing. In
bypass mode, the loads are directly connected to the line power without any conditioning. The ATS and GTS can
be used alone or together to allow the use of 3 different back-up sources (line, batteries and or generator). Refer
to the ATS/GTS Installation Manual (Alpha P/N 020-161-B0) for details.
WARNING!
Make sure you have read and understood the instructions given in the UATS/UGTS In-
stallation Manual before making any connection to the supply.
