WARNING!
• Many cables are connected in these parallel systems, therefore it is strongly required
that cables must be connected according to correct line sequence (R-R, S-S, T-T,
N-N). Otherwise, any misoperation may cause the system running failed.
• In diagram 2, INCORRECT line sequence (R-R, S-S, T-T, N-N) will damage the inverter.
To avoid the damage, set the default Enable in External ATS interface under the
Advance Settings as Disable.
