SOLID-STATE PULSE OUTPUT
The meter has one normally open (N.O.) KY Form A output and one normally
closed (N.C.) solid-state output.* One is dedicated to import energy (Wh), and
the other to Alarm. See the Setup section for conguration information.

Over-Current Protective
Device** (not supplied)
The solid state pulse outputs are rated for 30 VAC/DC nom.
Maximum load current is 100 mA at 25°C. Derate 0.56 mA per °C above 25°C.
* While the relay used for the Phase Loss contact is Normally Closed (contacts
are closed when the meter is not powered), closure indicates the presence of an
alarm; either loss of phase, when the meter is powered, or loss of power when
the meter is not. The contacts are open when the meter is powered and no
phase loss alarm conditions are present.
** The over-current protective device must be rated for the short circuit current
at the connection point.
