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.

at the connection point.
