QUICK INSTALL GUIDE
CONTENTS
The Enphase Communications Kit 2 INT enables the IQ Gateway Metered
to communicate with the IQ Battery 5P. The device has a USB Type-C port,
two Control cable ports, and a drain port.
The Communications Kit 2 INT includes the following accessories:
• One Control header with termination resistor
• One Control header without a resistor
• One USB Type-C to USB Type-A cable
• Zip-ties for cable management
• DIN rail adapters and screws
• Two spare control headers
The USB port connects the Communications Kit 2 INT to the IQ Gateway.
This enables communication between the device and the IQ Gateway.
The Control headers must be installed on the Control ports on the Commu-
nications Kit 2 INT.
(Model: COMMS-KIT-INT-02)
Installing the Enphase Communications Kit 2 INT
The Enphase Communications Kit 2 INT (COMMS-KIT-INT-02) enables wired communication between IQ Gateway Metered and IQ Battery 5P using Control
(CTRL) cables.
Read and follow all warnings and instructions in this guide. Do not proceed if you do not fully understand any of the concepts, terminology, or hazards outlined
in these instructions. These instructions are not meant to be a complete explanation of installation of an IQ Battery 5P system. Use the IQ Battery 5P Quick
Install Guide along with this document to plan your installation. All installations must comply with local codes and standards.
Torque details of Control cable are given below:
DANGER! Risk of electric shock. All sources to equipment
being serviced must be disconnected external to the device.
Storage circuits must ALWAYS be isolated via a circuit
breaker or isolator switch before working on any part of the
system.

INSTALLATION
Preparation
A ) Install the Communications Kit 2 INT in a IP3X or higher-rated enclosure
with adequate space for cable routing. It is recommended to install both
the IQ Gateway and the Communications Kit 2 INT in the same enclo-
sure.
B ) The enclosure should have access to an Earth terminal bar.
C ) Based on your installation design, identify if the Communications Kit 2 INT
is a terminating node or a non-terminating node in the daisy chain of de-
vices connected via a Control cable on the site. The installation procedure
varies accordingly as described later in the document.
D ) Make sure the system is powered off before you begin the installation.
E ) Ensure that you have the below tools and materials for the installation:
a. Torque terminal screwdrivers and wire stripper
b. Control cables
F ) Install the wired Control headers on the unit. Refer section 2 Wiring the
Communications Kit 2 INT.
G ) Connect the device to an IQ Gateway Metered with the USB cable
provided.
H ) Connect cable from Earth bar to the PE port on the device.
I ) Switch-on the IQ Gateway Metered.

✓NOTE: Use a wire stripper to strip the jacket of control communication
cable.
• To ensure proper control (CTRL) cable connection with IQ Batteries
follow the guidelines outlined below while connecting the cable to the
headers.
WARNING! Failure to follow wiring guidance will result in the
system being unable to detect devices leading to commission-
ing and operation failures.

• Ensure that both ends of the CTRL cable twisted pair conductors are
inserted into the header as shown above.
• Connect drain wire to the drain terminal only at one end of a CTRL cable.
Do not connect drain wires at both ends of a CTRL cable. Please follow
guidance based on section 3 Control (CTRL) wiring between system
components.
✓NOTE: To avoid mis-wiring, note the conductor colour as well as the
number on the conductor cores. The gure alongside and the table below
show the mapping of terminals on the header to the conductor colour and
number on wire core.

Twisted pair 2 – Black – CTRL (G)
Twisted pair 1 – White – CTRL (H)
Twisted pair 2 – White - Not used

TIP: Before pulling the cable through any conduit perform continuity checks
and label each end of all the conductors with small coloured clips or stickers
(with the same numbering as the headers). This will enable easy identication
of conductors and avoid mis-wiring.
The following table below provides mapping of the header numbers, control
communication signals, and twisted pair wire designation for the recom-
mended LAPP cables:
CTRL HEADER NUMBERS CTRL SIGNALS LAPP WIRE DESIGNATION

Screw terminal 2 CTRL H Twisted pair 1 – White
Screw terminal 3 CTRL G Twisted pair 2 – Black
Screw terminal 4 Not used Twisted pair 2 – White (not used)
Wiring the Communications Kit 2 INT
Strip cable insulation as per the following image. Keep the terminating
resistor only on the devices which are on either end of the control com-
munication bus and remove the resistor from all other devices.

Control wiring guidance for the installing IQ Battery 5P(s):
Refer to the following wiring sequences to understand the position of header with termination resistor, wiring order, and drain wire termination location.
✓ NOTE: Total length of CTRL wiring across the system should not exceed 100 meters to ensure system operates as per specications.
✓ NOTE: Ensure following guidelines are followed to avoid failures during system commissioning:
• One header with termination resistor should be installed on the component located at each end of the control network.
• The drain wire should only be terminated on one end of control wiring between system components.
• It is recommended that the drain wire be terminated at the component from which the control wiring for the section is initiated.
Following are the two common wiring sequences:
Sequence 1: Communications Kit 2 INT - IQ Battery 5P(s)
Sequence 2: IQ Battery 5P - Communications Kit 2 INT - IQ Battery 5P

The following table provides termination resistor locations for the above sequences:

The Communications Kit 2 INT needs IQ Gateway software version 8.3 or
higher to work with other Enphase Energy System components.
A ) Download the Enphase Installer App mobile application from iOS App
Store or Android Play Store and open it to log on to your Enphase In-
staller App account. With this app, you can connect to the IQ Gateway
to track system installation progress. You may also download the app
from the Enphase website at enphase.com/toolkit.
B ) Log in to the Enphase Installer App on your mobile device and down-
load the latest version of IQ Gateway software. To do so, go to the
“Settings” tab in the Enphase Installer App and use the “Update Now”
button under IQ Gateway Software.
C ) After the IQ Gateway update to version 8.2 or higher, scan the devices
to ensure they are identied as component of the Enphase Energy
System.
D ) Verify the devices are connected by navigating to:
“Devices” > “IQ Battery” > <serial number>
