Product Overview
Ketra’s X2 keypad oers users a classic button-style interface for the
complete control of a lighting system.
X2s come in two models: a wireless KetraNet Mesh controller and a wireless KetraNet
Mesh controller with onboard incandescent dimmer. The latter is ideal for spaces where
both Ketra and traditional lighting sources need to be controlled. Fitting within a
standard wall box and either Decora® or Claro wall plates, the X2 is perfect for retrofit
installations as well as new construction.

Installation
X2-ND AC Input, Non-dimming
New Construction
1. Install wall box (single gang wall box with at least 14 in volume only).
2. If installing in a multigang box, the side-fins must be removed for fit (see figures 2 and 3).
3. Run power to wall box utilizing stranded or solid core 1218 AWG wire (see figure 4).
4. Prepare the wire for connection to lead wire: A. Strip 8.5 mm of wire for insertion into the wire nut.
B. Twist the stranded wire to prevent fraying (tinning optional).
5. Using the provided wire nuts, attach each X2 lead wire to the corresponding conductor. Black-Line,
White-Neutral, Green-Ground (see figure 5).

6. Ensure that no conductors are visible after insertion, and that no stray wires are exposed.
7. Carefully tuck wires back into wall box.
8. Mount the X2 to the wall box using supplied fasteners. Leave the fasteners snug, not fully tight
(see figure 6).
9. Secure Wall Plate Mount to the X2 using the supplied fasteners (see figure 7).
Note: If the X2’s button chassis is not aligned with the wall plate mount, remove the mount and
adjust the position of the X2. Secure the wall plate mount with the fasteners when satisfied.
10. Place one serial number sticker on the back of the wall plate. The other can go on building plans or
control drawings (see figure 8).
11. Attach Wall Plate to Wall Plate mount. It will snap into place (see figure 9).
12. Energize circuit.
Note: Indicator lights will power on if unit is properly wired.

Retrofit Important Notes
•This wiring scheme is for standard in-line 2-Way light switches.
•The wall box should have a volume of 14 in or greater.
•The X2 does not have to be on the same circuit as any Ketra fixtures, as all control signals are wireless.
•Ketra fixtures to be controlled by the X2 should have an uninterrupted source of power. They should
NOT be wired to a light switch or other intermediary device that could cut their power. If you are
replacing lamps that are already wired to a light switch, it is recommend that the light switch be
physically replaced by the X2 (see figure 10).
Retrofit Instructions
1. Turn o power feed to the switch to be replaced.
2. Remove existing switch.
3. Continue with step 3 in the New Construction section, page 13.

Retrofit Important Notes
•This wiring scheme is for standard in-line dimmer.
•Wall box should have volume of 14 in or greater.
•The X2 Keypad and Ketra products require a constant, uninterrupted source of electricity. Power
needs to be run directly to Ketra fixtures being controlled by the X2 Keypad. Ketra fixtures to be
controlled by the X2 Keypad do not have to be connected to the same circuit, as the control signal is
wireless. However, non-Ketra fixtures will need to be on the same circuit and wired in-line if they are
to be controlled by an X2 with onboard incandescent dimmer.
•For a dimmer retrofit installation using incandescent loads, the incoming and outgoing line
connections should NOT be tied together. Instead, the incoming line should be tied to the X2’s black
line wire, while the outgoing line is tied to the X2’s red dimmed-line wire. Refer to page 13’s “X2
Keypad: Incandescent Dimmer” wiring diagram for an illustration of the proper wiring.
1. Turn o power feed to the switch to be replaced.
2. Remove existing switch.
3. Continue with step 3 in the New Construction section for the non-dimming model, page 13.

Replacing Button Chassis
The X2’s button chassis can be replaced. The replacement chassis must have the same button layout as
the original. To replace the button chassis, follow these steps:
1. Pull airgap switch out.
2. (If X2 already installed) Snap the wall plate o of its mount, and then unscrew and remove the mount.
Save screws.
3. Using a Phillips (PH1) screwdriver, unscrew the bottom-right screw that holds the button chassis in
place (see figure 10).
4. Apply pressure to exposed left edge of button chassis until it pops loose, and then gently remove
(see figure 11).
5. If removing the chassis detached the light guide from the board, reapply the light guide. The light guide
is a thin, black rubber strip with chimneys on top (see figure 12). To reapply, fit the two pegs on the
underside of the light guide into the two square holes on the board.
Note: The light guide’s orientation matters. Its surface should have a groove at the very bottom, just
above the last chimney.
6. Apply replacement button chassis immediately, applying equal pressure to all four corners to ensure
that the new chassis snaps into place.
Note: Your replacement chassis must have the same button layout as the original.
7. Reapply the bottom-right screw that holds the chassis in place. Ensure airgap switch is pressed in fully.
