Method B:
Grounding with unused mounting holes. You can use the frame edge grounding holes or unused
mounting holes on the DMEGC ACM for installing grounding devices.
Align a grounding clamp to the frame hole and place a grounding bolt through the grounding clamp and frame.
Place the toothed side of the washer as shown and fasten the nuts.
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. This guide leads you through the following
：
Connecting the Envoy-S
Detecting devices and scanning the installation map
Connecting to Enlighten
Registering the system
Building the virtual array
NOTE:
When the utility requires a profile other than the default IEEE 1547 (for example grids
managed by Hawaii Electric Industries [HEI] including HECO) you must select an appropriate
grid profile for your installation. You can set the grid profile through Enlighten, during system
registration, or through Installer Toolkit at any time. You must have an Enphase Envoy
communications gateway to set or change the grid profile. For more information on setting or
changing the grid profile, refer to the Enphase Envoy-S Installation and Operation Manual at
enphase.com/support.
