Drilling guidelines
4. Drilling guidelines
1. Step 1 - mark the spots locations on the table
1. Make sure it’s according to the quantity requested per table
2. Mark all the locations before drilling and make sure all are aligned vertically and
horizontally
3. Make sure not to mark a place above a leg or a bracket
4. When marking the drill locations use painters tape, this will prevent surface
chipping while drilling see Figure 1: Marking the Charging Spots location
Figure 1: Marking the Charging Spots location
Figure 2: Drilling over a bracket
2. Step 2 - Verify again table thickness
The charging spot can be installed in tables between ¾” to 3” (19.05 mm – 76.2 mm)

Drilling guidelines
3. Step 3 –Drilling
General guidelines:
a. Drilling can be done with a hand tool
b. Make sure the hole saw is facing exactly 90 degrees to the surface
c. It is recommended to use a bit as part of the hole saw
d. Make sure drilling area is covered with painters tape to avoid surface chipping
see Figure 1
NOTE: After drilling, make sure to clean burrs and splinters around top ream in order
to ensure proper fit.
NOTE: Charging Spot requires a wooden substrate underneath any stone surface

Charging Spot Installation
5. Charging Spot Installation
In order to power the Charging Spots, they should be connected to a power source.
The system works on a safe DC power, which is converted from the AC power outlet
in the wall by a power adaptor.
1. Charging Spot Kit –Components:
Table 4: Charging Spot Kit components list
Installation Hardware
A. 4 x #6 3/8” screws
B. 4 x #6 1” screws
C. 4 x screw plugs
Charging Spot Assembly Parts
D. 1 x surface-mounted cap
E. 1 x silicone gasket
F. Magnetic module sub-assembly
G. Electronics module sub-assembly
H. Charging Spot Housing
I. 1 x centering spacer ring (for Sub-
surface assembly only)

Charging Spot Installation
2. Required tools and parts:
1. #2 Phillips screw driver
2. Narrow Flat head screw driver
3. Cutting pliers
4. 16/2, stranded, general purpose low voltage wire, CL3 & UL rated
5. Approved Powermat power supply
6. Transparent Silicone

Charging Spot Installation
4. Before you start
1. Inspect drilled holes/cavities and verify they are clean of burrs and obstructions.
2. Determine the intended orientation of all Charging Spots in relation to the
surface based on wiring layout and surface frame / legs.
Table 5: Charging Spot orientation options
Perpendicular Orientation
Parallel Orientation

Charging Spot Installation
5. Magnetic Module Subassembly - Surface Mounted
1. Separate magnetic module sub-assembly (F) from electronics module sub-
assembly (G) by pressing the quick release connector lever and pulling gently.
Figure 4
2. Hold the magnetic module such that the quick-release connector points toward
the desired installation orientation of the electronics module and housing.
3. Place the cap (D) on the coil encasing in accordance with the desired direction of
the artwork printed on the cap (facing the intended user), then turn the cap a ¼
of a turn, such that it cannot be separated by pulling it away from the magnetic
encasing. Try to pull it out to verify it is properly connected.
Figure 5

Charging Spot Installation
4. Add 3-4 dots of silicone on inner bottom lip of the cap (D). This silicone will
keep the cap tightly secured to the surface.
Figure 6
5. Pass the heat sink mount through the hole from the top of the surface, and press
the surface-mounted cap onto the hole, so the cap shoulders sit snug against the
surface. If the cover fits unevenly, remove and identify the problem. File any burrs
as needed.
Figure 7
6. Using one hand, firmly press the cap against the surface to prevent it from rising,
and the artwork from rotating. Reach from underneath the surface, and using
your other hand, tighten the 3 latches evenly until the cap and the coil encasing
sit securely in place.

Charging Spot Installation
Figure 8
7. Verify the cap sits tight against the surface and that it cannot be turned or pulled
out.
8. Slide the electronics module sub-assembly (G) into place to connect with the
magnetic module sub-assembly (F) until clicked in place.
Figure 9
9. Accurately align and square the electronic module subassembly according to the
desired orientation of the CS for wiring. Secure the heat sink mount to the
surface using 3 x #6 3/8” screws (A). Secure electronic module sub-assembly (G)
using 2 x #6 1” screws (B).
Figure 10

Charging Spot Installation
6. Magnetic Module Subassembly –Sub-surface Installation
1. Separate magnetic module subassembly (F) from electronics module
subassembly (G) by pressing the quick-release connector lever and pulling gently.
2. Place the centering spacing ring subassembly (I) on top of the coil encasing on
the magnetic module subassembly
3. Pointing the quick-release connector in the general intended orientation of the
electronics module, insert the coil encasing all the way into the cavity, and hold it
in place. It is important to verify the encasing sits flat and tight against the
surface layer.

Charging Spot Installation
4. While pressing the coil encasing firmly upwards, tighten the 3 latches firmly into
the cavity.

Wiring
6. Wiring
1. Before you start
oWiring should be done as discreetly as possible
oIt is required to use 16gage DC wires at the minimum
oWires may not ‘jump’ from two surfaces (i.e. counters) if there is a gap between
surfaces, wiring should run down the leg of one counter, along the baseboard or
underneath the chair rail, and then up the leg of the next counter.
oIt is recommended to use wire channels in order to protect the wires
oAll movable tables should use a tether box (See design guidelines)
oWire channels should either be in a horizontal or vertical direction until hitting
either the tile base at the bottom of the wall or the chair rail, whichever is closer.
Do not run wire channeling in anything other than a vertical or horizontal
direction.
oWhen running AC power from a floor outlet to the underside of a community
table, a black floor plate and black conduit should run up the leg of the table to a
junction box mounted on the underside of the table
oThe junction box will split and run AC power to the power strips and DC power to
a power supply that will be wired to the Charging Spots
oLoose wires should be replaced with conduit on underside of table
Important note: When working with power take necessary percussions to avoid safety
hazards

Wiring
2. Charging Spot Wiring
1. Determine wiring path, and identify the jacks you would like to use for your
input.
2. Using a narrow flat head screwdriver, push the respective terminal button, and
insert the positive wire (red or sometimes white) into the red DC push wire jack
terminal, and the negative wire (black) into the grey DC push jack terminal.
NOTE - Make sure to connect wire polarities correctly. Reversing polarities
will cause permanent damage to the Charging Spot.
Figure 11: Charging Spot electrical module, wiring locations
3. Take out the sticker attached to the Charging Spot and place it on the Charging
Spot housing (H).
4. Cut the proper knockouts in the Charging Spot housing (H) using cutting pliers,
5. Secure the Charging Spot housing to the surface using 4 x #6 1” screws (B)
Figure 12

Wiring
6. Place screw plugs (C) over mounting screw holes, and press until flush.
Figure 13
7. Connect wires to the Powermat-approved power supply. As previously, make
sure to match polarities according to the respective wire color-coding or to the
daisy chain
3. Using Powermat Daisy-Chain Wiring Harnesses
Powermat uses specially designed wiring harnesses to provide the necessary power to
the table mounted Charging Spots. These wiring harnesses are daisy chained within
the table in one of the following two different configurations.
‘Inline’ Wiring Harness
‘T6’ Wiring Harness
These wiring harnesses can be configured to supply power to up to 8 CSs from one
power supply.
1. Inline or one way wiring harness:
