Does the ATS48 unit provide separate power terminals to connect cables that feed the line side of the shorting contactor?
No. None of the ATS48 units have separate terminals for the line side of the shorting contactor. The ATS48 L1, L2, L3 terminals are for incoming line connections. This may require that separate terminal blocks be used to connect the line side of the shorting (bypass) contactor. Note: There are contactor load terminals provided, A2, B2, C2.
