2.4 ATS/GTS Option
The ATS (automatic transfer switch) and the GTS (generator transfer switch) are two separate
optional add-on switching units for the Micro family. The ATS provides power and/or bypass
capability (automatic or manual) so the operator may disconnect the Micro family of products
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.
Make sure you have read and understood the instructions given in the ATS/GTS
Installation Manual before making any connection to the supply.
Installation and wiring instructions are provided on a separate installation manual (020-
161-B0).
