QUICK INSTALL GUIDE Model number: X-IQ-NA-HD-125A
Installing IQ Combiner 4/4C Hold Down Kit
This is the Hold down kit for IQ8 PV breakers in IQ Combiner 4/4C. The hold down kit includes one retainer and 2 screws. Each hold down kit supports two
breakers to be installed on the same side of the busbar.
Follow these steps to install the Enphase Hold Down Kit in the IQ Combiner 4/4C:
DANGER: Risk of electric shock. Always de-energize the load center before beginning wiring.
A) Turn off power ahead of the IQ Combiner 4/4C before installing the Hold Down Kit.
B) Refer to Figure 1 and align the retainer over rectangular hole in interior backpan and outside of main bus (Locate the two bus stab locations as
shown in Figure 2)
C) Snap-in end of retainer at interior backpan by pushing downward. The retainer should t into the available space in the backpan with part of the
plastic in the rectangular hole and the other side of the retainer under the busbar.
D) Install the circuit breakers onto the bus.
WARNING: Risk of equipment damage. Do not scratch, nick, bend or otherwise damage bus.
E) Assemble #5-20 screw into hole in the breakers. Thread into retainer and tighten. Torque screws to 13 lb in (1.5Nm).

SAFETY
IMPORTANT SAFETY INSTRUCTIONS. SAVE THESE INSTRUCTIONS. This guide contains important instructions that you must follow during installation
and maintenance of the Enphase IQ System Controller. Failing to follow any of these instructions may void the warranty (enphase.com/warranty).
In Case of Fire or Other Emergency
In all cases:
•
If safe to do so, switch off the AC breaker for the IQ System Controller circuit,
and if an isolator switch is present, switch off the AC isolator for the IQ
System Controller circuit.
•
Contact the re department or other required emergency response team.
•
Evacuate the area.
In case of re:
•
When safe, use a re extinguisher. Suitable types are A, B, and C dry chemical
re extinguishers. Additional extinguishing media include carbon dioxide, or
alcohol-resistant foams.
In case of ooding:
•
Stay out of water if any part of the IQ System Controller or wiring is
submerged.
•
If possible, protect the system by nding and stopping the source of the
water, and pumping it away.
•
If water has contacted the UNIT, call your installer to arrange a inspection.
If you are sure that water has never contacted the battery, let the area dry
completely before use.
In case of unusual noise, smell or smoke:
•
Ensure nothing is in contact with the IQ System Controller or in the venting
area on top of the IQ System Controller.
Safety and Advisory Symbols
DANGER: This indicates a hazardous situation, which if not avoided, will
result in death or serious injury.
+
WARNING: This indicates a situation where failure to follow instructions
may be a safety hazard or cause equipment malfunction. Use extreme
*
caution and follow instructions carefully.
NOTE: This indicates information particularly important for optimal system
✓
operation. Follow instructions carefully.
Safety Instructions
DANGER: Risk of electric shock. Risk of re. Do not attempt to repair the
IQ Gateway; it contains no user-serviceable parts. Tampering with the IQ
+
Gateway will void the warranty. If the IQ Gateway fails, contact Enphase
Customer Support for assistance (enphase.com/en-us/support/contact).
DANGER: Risk of electrocution! Do not install CTs when current owing
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 man-
ner not specied 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 IQ Combiner4/4C without
+
rst 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 re. Only qualied personnel should
troubleshoot, install, or replace the IQ Combiner 4C or IQ Combiner 4.
+
DANGER: Risk of electric shock. Improper servicing of the IQ Combiner 4C
or IQ Combiner 4 or its components may result in a risk of shock, re or
+
explosion. To reduce these risks, disconnect all wiring before attempting
any maintenance 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 re. Only use electrical system
components approved for wet locations.
+
DANGER: Risk of electric shock. Risk of re. Ensure that all wiring is correct
and that none of the wires are pinched or damaged.
+
Safety Instructions continued
DANGER: Risk of electric shock. Risk of re. 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, bracelets,
necklaces, watches etc. when working with batteries, photovoltaic modules
or other electrical equipment.
DANGER: Risk of electric shock. Risk of re. Before making any connections
verify that the circuit breaker(s) are in the off position. Double check all
+
wiring before applying power.
DANGER: Risk of electric shock. Risk of re. Do not wire unused terminals
or terminal blocks on the IQ Gateway.
+
WARNING: Risk of electric shock. To maintain the warranty,
do not modify the dead-front other than to remove ller plates, as needed.
*
WARNING: Before installing or using the IQ Combiner 4C or IQ Combiner 4,
read all instructions and cautionary markings in the technical description
*
and on the equipment.
WARNING: Use the circuit breakers in the Enphase IQ Combiner 4C or
IQ Combiner 4 only for serving Enphase equipment. No other loads are
*
allowed.
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
*

WARNING: The IQ Combiner 4C and IQ Combiner 4 have a pre-installed
heat shield attached 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).
*
WARNING: BONDING BETWEEN CONDUIT CONNECTIONS IS NOT AUTOMATIC AND MUST BE PROVIDED AS PART OF THE INSTALLATION.
*
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 IQ Combiner 4C or IQ Combiner 4 in the eld with 75°C or
✓
higher copper conductors sized per local code requirements and voltage
drop/rise considerations.
NOTE: Use Class 1 wiring methods for eld wiring connections to terminals
✓
of a Class 2 circuit. Use 14 to 6 AWG wire for branch circuits and 14 to 3
AWG for output circuits. Select the wire gauge used based on the protection
provided by the circuit breaker(s)/fuses. Overcurrent protection must be
installed as part of the system installation.
NOTE: To ensure optimal reliability and to meet warranty requirements, the
✓
