APPENDIX IV: SOLAR INSTALLATION
This document describes only the necessary modifications for using the MNC with a solar-based power source.
Consult the manufacturer’s instructions for assembly, wiring, and grounding the solar array.
• Disconnect AC power to the unit before you begin.
• Switch the AC breaker (labeled “AC”) and the battery breaker (labeled “BATT”) to the OFF position.
SOLAR POWER INSTALLATION NOTES:
• Solar array installation should be performed only by qualified, licensed personnel, and conform to all relevant
regulations
• The solar array should provide AC power, 90-264V, 50 / 60Hz, 100W
• For any solar installation, ensure the MNC battery has been removed. It should be shipped to you without a battery.
Contact Mueller Systems if you have received an MNC with a battery included.
SOLAR BATTERY MONITORING WIRING
The solar array’s Remote Sensor Module (RSM) should be connected to the gateway via General Cable E1004S.41.10. Thread
the four-wire bundle through a protective sheath attached at the Ethernet hole on the bottom right of the collector.
Once connected, the gateway can forward alarms regarding the solar array voltage to the Mi.Host interface.
