DMEGC AC Module Installation Manual 1.3 Safety and Advisory Symbols To reduce the risk of electric shock, and to ensure the safe installation and operation of the DMEGC Module System, the following safety symbols appear throughout this document to indicate dangerous conditions and important safety instructions.
Page 5 DMEGC AC Module Installation Manual WARNINGS: Before installing or using the Enphase Microinverter, read all instructions and cautionary markings in the  technical description, on the Enphase equipment and on the photovoltaic (PV) equipment. Do not connect Enphase Microinverters to the grid or energize the AC circuit(s) until you have completed all of ...
Page 6 DMEGC AC Module Installation Manual WARNING: Risk of equipment damage The Enphase Microinverter is not protected from damage due to moisture trapped in cabling systems. Never mate  microinverters to cables that have been left disconnected and exposed to wet conditions. This voids the Enphase warranty.

Use the terminator to seal the conductor end of the Enphase Q Cable; no other method is allowed. 2. The Enphase IQ System The Enphase IQ System includes: Enphase IQ Microinverters for DMEGC AC Module, The smart grid ready Micros convert the DC output of  the PV module into grid-compliant AC power.
Page 8: How The Ac Module Works
DMEGC AC Module Installation Manual 2.1 How the AC Module Works The Enphase Microinverter maximizes energy production by using a sophisticated Maximum Power Point Tracking (MPPT) algorithm. Each Enphase Microinverter is individually connected to one PV module in your array. This configuration enables an individual MPPT to control each PV module, ensuring that maximum power available from each PV module is exported to the utility grid regardless of the performance of the other PV modules in the array.

DMEGC does not provide a warranty for clamps. The module warranty DMEGC provides shall be voided if  clamps selected by the customer are an improper material or size.
Page 17 DMEGC AC Module Installation Manual Step 9: Terminate the Unused End of the Cable Terminate the unused end of the Enphase Q Cable (See Figure 4-6).  Remove 13 mm ( 0.5 inch) of the cable sheath from the conductors. Use the terminator loop to measure 13 mm.
Page 18 DMEGC AC Module Installation Manual Refer to the wiring diagrams in Figure 4-7 for more information. Wire colors are listed in the following table.  L1-Black Wire Colors L2-Red Figure 4-7. Sample Wiring Diagram Step 11: Energize the system Turn ON the AC disconnect or circuit breaker for the branch circuit.
Page 19 DMEGC AC Module Installation Manual Step 12: Wiring General All wiring should be done in accordance with applicable electrical codes.  All wiring should be done by a qualified, licensed professional.  Wiring should be protected to help ensure personal safety and to prevent its damage.
Page 20 Verify that all fittings are properly installed to protect cables against damage and prevent moisture intrusion.  Check your local codes for requirements.  Step 15: Ground the DMEGC ACMs Choose to use grounding clamps or module mounting holes to ground the modules. Or, you can use a reliable  third-party grounding system.
Page 21 Place the grounding wire through the grounding clamp and tighten the nuts. Method C: Grounding with third party hardware. You can use third party grounding devices for grounding of DMEGC modules, but these devices must be reliable and must be operated per manufacturer instructions. Step 16: Set Up and Activate Monitoring Refer to the Enphase Envoy-S Quick Install Guide to install the Envoy-S and set up system monitoring and grid management functions.
