Over-Current Protective Device**
(not supplied)
The solid state pulse outputs are rated for 30 VAC/DC nom.
The 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.
All pulse inputs/outputs and communication circuits are only intended to be connected to non-hazardous circuits (SELV or Class 2).
Do not connect to hazardous voltages.
Solid State Output
• Use this meter in either Free Topology or Bus Topology LonWorks network configurations.
• Twisted pair connections to the meter are not polarity sensitive.
• Attach the meter at any point in a Free Topology configuration, but the total network cable length must be less than
500 meters.
• Free Topology configurations require one terminator (Echelon TP/FT-10 Free Topology Terminator or equivalent), which
can be attached at any point in the network.
• In Bus Topology configurations, connect loads sequentially (in a daisy chain), except for stubs, which must be less than
3 meters in length. The total network cable length must be less than 2700 meters.
• Bus Topology configurations require two terminators (Echelon TP/FT -10 Free Topology Terminator or equivalent, one
at at each end of the network.
• The Shield connection is not internally connected to the ground connection on the meter.

For all terminals:
• When tightening terminals, apply the correct torque: 0.37 to 0.44 ft·lb (0.5-0.6 N·m).
• Use 14-24 gauge (2.1-0.2 mm 2 ) wire.
