External Protection And Isolation Devices - ABB ATS-16 A Operating Manual

3.3. External Protection and Isolation Devices

External devices for the protection of cables and for isolating the ATS-16 A and UPS must be installed
upstream and downstream of the equipment. Select and configure the isolating device upstream in ac-
cordance with the ATS-16 A input 16 A breakers.
Disconnecting devices must be provided in building installations and other locations.
All protection devices (circuit breakers and fuses) placed upstream of the ATS-16 A input and downstream
to ATS-16 A output line have to be installed for the protection of both the cables and the equipment and
in coordination with both ATS-16 A input protection (fuses) and ATS-16 A overload capacities.
IF THE ATS-16 A'S OVERLOAD CAPACITIES ARE EXCEEDED, THE UNIT WILL CUT-OFF THE
OUTPUT LOAD.
DEPENDING ON THE OVERLOAD CHARACTERISTICS, THE ATS-16 A WILL EITHER TRIP THE
INPUT FUSES OR DRIVE THE INTERNAL POWER RELAYS INTO THE OPEN POSITION.
