DANGER
: Risk of electric shock. Risk of fire. Do not attempt to repair the
Envoy-S; it contains no user-serviceable parts. Tampering with or open-
ing the Envoy-S will void the warranty. Warranty void if cover removed. If
the Envoy-S fails, contact Enphase Customer Support for assistance
(enphase.com/en-us/support/contact).
+
DANGER:
Risk of electrocution! Do not install CTs when current flowing
in the sensed circuit. Always install CT wires in the terminal blocks before
energizing the sensed circuit.
+
DANGER
: Risk of electric shock. Do not use Enphase equipment in a
manner not specified 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 install the AC Combiner
without first removing AC power from the Enphase System. Ensure the
power coming from the microinverters is de-energized before servicing
or installing.
+
DANGER
: Risk of electric shock. Risk of fire. Only qualified personnel
should troubleshoot, install, or replace the AC Combiner.
+
DANGER
: Risk of electric shock. Improper servicing of the AC Combiner
or its components may result in a risk of shock, fire or explosion. To
reduce these risks, disconnect all wiring before attempting any mainte-
nance or cleaning.
+
DANGER
: Risk of electric shock. Always de-energize the AC branch
circuit before servicing. While connectors are rated for disconnect under
load, it is a best practice to de-energize before disconnecting.
+
DANGER
: Risk of electric shock. Risk of fire. Only use electrical system
components approved for wet locations.
+
DANGER
: Risk of electric shock. Risk of fire. Ensure that all wiring is
correct and that none of the wires are pinched or damaged.
+
DANGER
: Risk of electric shock. Risk of fire. Do not work alone. Someone
should be in the range of your voice or close enough to come to your aid
when you work with or near electrical equipment. Remove rings, brace-
lets, necklaces, watches etc. when working with batteries, photovoltaic
modules or other electrical equipment.
+
DANGER
: Risk of electric shock. Risk of fire. Before making any connec-
tions verify that the circuit breakers are in the off position. Double check
all wiring before applying power.
+
DANGER
: Risk of electric shock. Risk of fire. Do not wire unused termi-
nals or terminal blocks on the Envoy-S.
+
DANGER
: Risk of arcing over time. You must re-torque all field wiring
connections after one hour.

WARNING
: Before installing or using the AC Combiner Box, read all
instructions and cautionary markings in the technical description and on
the equipment.
*
WARNING
: Use the circuit breakers in the Enphase AC Combiner Box
only for serving Enphase equipment. No other loads are allowed.
FCC Statement
: This equipment has been tested and found to comply with the limits
for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate radio frequency energy
and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interfer-
ence will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning the
equipment off and on, you are encouraged to try to correct the interference by one or
more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and the receiver.
- Connect the equipment into an outlet on a circuit different from that
to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
Changes or modifications not expressly approved by the party responsible for compli-
ance may void the user’s authority to operate the equipment.
This Class B digital apparatus complies with Industry Canada ICES-003.

WARNING
: This unit is not provided with a GFDI device. This inverter or
charge controller must be used with an external GFDI device as required
by the Article 690 of the National Electrical Code for the installation
location.
*
WARNING
: The AC Combiner Box has a pre-installed heat shield at-
tached to the enclosure door. Do not remove the heat shield.
*
WARNING
: This product is intended for operation in an environment
having a maximum ambient temperature of 46ºC (115ºF).
✓
NOTE
: Perform all wiring in accordance with all applicable local electrical
codes, with the Canadian Electrical Code, Part I, and with the National
Electrical Code (NEC), ANSI/NFPA 70.
✓
NOTE
: Protection against lightning and resulting voltage surge must be
in accordance with local standards.
✓
NOTE
: Using unapproved attachments or accessories could result in
damage or injury.
✓
NOTE
: Install the AC Combiner Box in the field with 75°C or higher copper
conductors sized per local code requirements and voltage drop/rise
considerations.
✓
NOTE
: Use Class 1 wiring methods for field wiring connections to terminals
of a Class 2 circuit. Use 14 to 6 AWG wire for branch circuits and 14 to 4
AWG for output circuits. Select the wire gauge used based on the protec-
tion provided by the circuit breakers/fuses. Overcurrent protection must be
installed as part of the system installation.
✓
NOTE
: To ensure optimal reliability and to meet warranty requirements,
the Enphase AC Combiner Box must be installed according to the
instructions in this manual.
