PREINSTALLATION
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 Conguration
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.

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 N4ís 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 N4ís power indicator light will come on. It will be red while
the N4 boots up; afterward, it will turn white.

If you are unable to discover your N4s in Design Studio, conrm one of the following is true:
Option 1:
–Your computer is on the same subnet as all N4’s
OR
Option 2:
–Your computer is on the same network as the N4’s
–All N4’s are on the same subnet
–The N4’s have internet access
–Your computer has internet access
Controlling with the Ketra Mobile App
For instructions on using an N4 with the Ketra app, refer to our Mobile App Manual.
If you are unable to discover your N4s in the Ketra app, conrm one of the following is true:
OPTION :
–Your mobile device is on the same subnet as all N4’s
OR
OPTION :
–Your mobile device is on the same network as the N4’s
–All N4’s are on the same subnet
