Note: Software limits 2 alarms active at once power fault and one of major, minor or critical
alarms.
Alarms connector relay contacts are rated at 1 A with a maximum rating of 30 W(DC) / 60 VA
(AC).
Alarms connector external alarm (major and/or minor) reset is an optoisolated input that is
reverse voltage protected. A voltage of 3.3 V to 48 V input with a pulse width of at least 200 ms
is required to activate the alarm-reset function. Maximum current is 12 mA.
