Smart Distribution Panel with ATS 3
This product and this manual were designed for the 250-amp ATS. All wiring recommendations
were sized for this amperage in accordance with IEC 60364-5-52. This does not prevent you
from using the ATS at a lower current with smaller wire sizes. If you decide to operate this ATS
at a lower current, ensure that the wire sizes are in accordance with IEC 60364-5-52 or your
national standard.
Install this ATS in accordance with your national and local electrical standards.
When connecting Source 1 to the ATS, install a circuit breaker to protect the ATS from over-
current. This circuit breaker must be rated at 250A.
To reduce risk of electric shock or injury to persons, disconnect all sources of supply before
servicing. To disconnect all sources of supply, follow this procedure:
1. Set the Automatic Operation switch on the deadfront of the ATS to Disable.
2. Set the Source 1 switch on the ATS to OFF.
3. Set the Source 2 switch on the ATS to OFF.
4. Set the main Source 1 circuit breaker to OFF.
5. Set the main Source 2 circuit breaker to OFF.
6. If Source 2 is a generator, set the generator control switch to OFF, or set the generator control
switch to Manual, if OFF is not an option.
