IMPORTANT SAFETY INSTRUCTIONS.
SAVE THIS INFORMATION. This guide contains important instructions to follow during installation of the Enphase Q Aggregator.
WARNING: Hot internal surfaces.
DANGER: Refer to safety instructions.
DANGER: Risk of electric shock.
Safety Instructions
+
DANGER: Risk of electric shock. Do not use Enphase equipment in a manner
not specied by the manufacturer. Doing so may cause death or injury to
persons, or damage to equipment.
+
DANGER: Risk of electric shock. Be aware that installation of this equipment
includes risk of electric shock. Do not open without rst removing AC
power from the Enphase System. Disconnect the power coming from the
photovoltaics before servicing or installing.
+
DANGER: Risk of electric shock. Risk of re. Before making any connections
verify that the circuit breakers are in the off position. Double check all wiring
before applying power.
+
DANGER: Risk of electric shock. Risk of re. Only use electrical system
components approved for wet locations, including but not limited to conduit
ttings.
+
DANGER: Risk of electric shock. Risk of re. Use the circuit in the Enphase
Q Aggregator only for connecting Enphase Q Cable and Microinverters. No
other loads or sources are allowed.
+
DANGER: Risk of electric shock. Risk of re. Only qualied personnel should
install, troubleshoot, or replace the Enphase Q Aggregator.
+
DANGER: Risk of electric shock. Improper servicing of the
Q Aggregator or its components may result in a shock, re or explosion.
To reduce these risks, disconnect all wiring before attempting any
maintenance.
+
DANGER: Risk of electric shock. Risk of re. Ensure that all AC and DC wiring
is correct and that none of the AC wires are pinched, shorted, or damaged.
+
DANGER: Risk of electric shock. Risk of re. Protect the Q Aggregator with a
60 A maximum over current protection device (OCPD).
+
DANGER: Risk of electric shock. Risk of re. Do not attempt to repair the
Enphase Q Aggregator, other than to replace parts only as directed in this
guide. Tampering with the board or damaging the conformal coating will
void the warranty.
+
DANGER: Risk of electric shock. Risk of re. Make sure the conductors
are not damaged. If the exposed wires are damaged, the system may not
function properly.
+
DANGER: Risk of electric shock. Risk of re. Do not leave AC connectors
on the Enphase Q Cable uncovered for an extended period. You must
cover any unused connector with a sealing cap.
+
DANGER! Risk of electric shock. Some tasks are done with live circuits in
an outdoor rooftop environment. Always wear proper personal protective
equipment (PPE) for electrical and rooftop tasks.
*
WARNING: Do not expose any connectors to rain or condensation before
the connectors are mated.
*
WARNING: Install the Q Aggregator under the PV module to avoid direct
exposure to rain, UV, and other harmful weather events; mount the Q
Aggregator off of the roof surface for rain and snow resistance; and
always install the Q Aggregator with the label side up. Do not mount it
upside down.
*
WARNING: Risk of equipment damage. This product is intended for
operation in an environment having a maximum ambient temperature of
55ºC (131ºF).
*
WARNING: When installing the Enphase Q Cable, secure any loose cable to
minimize tripping hazard
*
WARNING: Before installing or using the Enphase Q Aggregator, read all
instructions and cautionary markings in the technical description, on the
Enphase System, and on the photovoltaic (PV) equipment.
;
WARNING: Risk of skin burn. The Enphase Q Aggregator may have very hot
interior surfaces. To reduce risk of burns, use caution when working with the
Q Aggregator.
✓
NOTE: For problems other than a blown fuse or physical damage, contact
Enphase customer service to obtain an RMA (return merchandise authoriza-
tion) number and start the replacement process.
✓
NOTE: Install the Q Aggregator in the eld with 75°C or 90°C copper
conductors sized per local code requirements and voltage drop/rise
considerations.
✓
NOTE: Using unapproved attachments or accessories may result in damage
or injury.
✓
NOTE: Use Class 1 wiring methods for eld wiring connections to
terminals of a Class 2 circuit. Use only 14 to 4 gauge wire. Select the wire
gauge used based on the protection provided by the circuit breakers/
fuses. Overcurrent protection must be installed as part of the system
installation.
✓
NOTE: When looping the Enphase Q Cable, do not form loops smaller than
4.75 inches (12 cm) in diameter.
✓
NOTE: Perform all electrical installations in accordance with all applicable
local electrical codes: the Canadian Electrical Code, part 1; the National
Electrical Code (NEC); ANSI requirements; and NFPA 70.
✓
NOTE: To ensure optimal reliability and to meet warranty requirements,
install the Enphase Microinverters and Enphase Q Cable according to the
instructions in this guide.
✓
NOTE: Protection against lightning and resulting voltage surge must be in
accordance with local standards.
