## Questions & Answers

**Q: is there an optically isolated pulse output available at termnals 5 and 6?  is this what the two gray connectors under the cover are for?**
A: Yes

**Q: I have a 2 stranded aluminum from box goingto camper will this work**
A: I use it on mine

**Q: L1 and l2 are 110v. will it measure both lines**
A: This is Single Phase Three Wire ,measure both lines L1,L2.
 L1,L2 works through meter which is 220v, N have not work through meter.
L1-N =110V, L2-N=110V, L1-L2=220V
This meter will not work on a single phase 120v 2-wire system.

**Q: Have an apt fed by 100amp double breaker in house panel. can i mount this next panel with pigtails to meter? apt feed is 240v. two hots and a neutral**
A: Yes. All you need are two hots and two small jumper wires as per the instructions. Then hook up whatever you wish to monitor as per the instructions. Its simple and easy. No neutral wire needed.
