Cover and energize the system
* WARNING: Before energizing, make sure that all IQ Batteries in the
system are properly installed and conductors terminated.
✓ NOTE: Check the box for updates on cover installation instructions.
A ) Check that the eld wiring compartment cover(s) for all IQ Batteries in
the system are closed and secured.
+ DANGER: Risk of electric shock. Before continuing, check that
IQ Battery units are properly wired and ground connection does not
have an L1 or L2 connection, as this introduces a safety hazard.
• Apply AC power to the IQ Battery circuits. Do NOT turn On the DC switch on
IQ Batteries.
• Using a voltmeter measure the IQ Battery chassis metal to ground (e.g.,
grounded conduit) and ensure no AC voltage source is present. If wiring is
incorrect, a ground fault may exist, and the AC voltage may read ~120 VAC.
If voltage is present, DO NOT touch the chassis, and immediately remove
AC power from the IQ Battery circuits.
• Remove AC power to the IQ Battery circuits and correct the wiring.
* WARNING: Before commissioning, the DC switch on the IQ Battery
shall not be turned on unless instructed in the Enphase Installer App.
Turning the DC switch On before it is instructed in the Enphase Installer
App can damage the IQ Battery.
