PRODUCT OVERVIEW
Ketra’s N4 Hub forms a bridge between Ketra
products and Ketra digital interfaces such as
Design Studio, mobile app, and API commands.
With multiple N4s, a user can integrate KNets, allowing for seamless installations no
matter how large. The Hub can also connect via Internet to Ketra’s cloud servers to
enable backup and remote maintenance functions.

PRE-INSTALLATION
N4 PLACEMENT
For ideal KetraNet Mesh wireless performance, position the N4 according to these guidelines:
• Keep within range: Place the N4 within 50 feet of at least one of the devices it will control.
Ideally, place as close as possible to all devices it will control.
• Avoid obstructions: Avoid having metal obstructions or walls between the N4 and the
nearest device it will control.
• Avoid metal enclosures.
• Separate from Wi-Fi devices: Maintain at least 6 feet of spacing between any KetraNet Mesh
product and Wi-Fi routers and access points.
The N4 is UL Damp Location-listed.
The N4 has a suggested clearance of 4 inches to ensure visibility of indicator lights and access to all ports. (See g. 5.)
NETWORK CONFIGURATION
The modem or router to which the N4 is connected must include a DHCP server from which the N4 can obtain an IPv4
address. (For the vast majority of modems and routers, this is the default.)
All N4s that will be part of an installation together must be on the same LAN (Local Area Network) subnet.

INSTALLATION
1. Remove a half-inch knockout from the junction box.
2. Mount the N4 to the junction box. Fit the N4’s connector into the opening created in step 1.
Secure the N4 by threading the provided threaded ring onto the mount.
Notes:
–
Orientation: The N4’s serial number (on the bottom) should face the access point.
The serial number may be necessary for commissioning and servicing.
–
Clearance: Remove nearby obstructions. This will ensure the visibility of the indicator lights
as well as access to all ports.
3. Splice the N4 into building power. Using the provided wire nuts, attach each lead wire to the corresponding
conductor. All connections should be made inside the junction box.
– Black: Line
– White: Neutral
– Green: Ground
4. Energize the circuit.
Note: Once power is connected, the N4’s power indicator light will come on. It will be red while the
N4 boots up; afterward, it will turn white.
STEP 1
APPLY POWER TO THE HUB
INSTALLATION
PAGE 11770-000027-02 r14N4 INSTALLATION GUIDE
STEP 2
CONNECT THE HUB TO THE LAN (LOCAL AREA NETWORK)
There are two methods of doing this, shown below. Choose the one that best ts the needs of the installation. Once a
connection is detected, the N4s Ethernet indicator, , will come on white.
OPTION 1: DIRECT CONNECTION TO MODEM OR ROUTER.
• Use a CAT5 or equivalent Ethernet cable
• Cable can be no more than 100 m (328 ft)

OPTION 2: CONNECTION TO A CHAIN OF N4S.
• Use either RJ45 port for input/output
• Maximum of 10 N4s per chain
• Use a CAT5 or equivalent Ethernet cable
• Cable can be no more than 100 m (328 ft)
Warning: If any N4 in the chain is powered o, all N4s further down will be unable to connect to the LAN.
