INSTALLATION
Electromagnetic Considerations:
Locate the charger at least 1” (25 mm) from any support structure. Assure that no metal is present above the transmitter
unit. Provide at least 11/2” (36 mm) of clearance above the charger, and 1” (25 mm) below the unit. If multiple chargers are
present, allow at least 6” (150 mm) spacing between each.
Identifying The Location of The Charging Point:
Since ecient power transfer relies upon close coupling of the receiver with the transmitter, it is important that the user be
able to accurately locate their handheld device directly above the transmitter for charging. As such, consideration should
be given to providing some form of location guide on the counter top. The prominence and styling of these visual guides
is a matter of installer preference, and should take into consideration the needs of the end user. In a setting where the
installation will be well known to a limited number of users, a subtle or even temporary location guide may be sucient.
In settings where users won’t be familiar with the location of the charging site, a more prominent marking would likely be
preferred, both to identify the availability of the site and the optimal placement for the handheld device to be charged.
Mechanical Details:
The charger should be mounted to the underside of a counter top. The installer should verify that the power and micro USB
ports are accessible after installation, and should plan for the routing of the DC power supply cable. The installer should
also plan for the mounting of the included power transformer. Lastly, the installer should plan for the routing of the AC cable
from the transformer to an available AC outlet.
Routing:
The transmitter coil must be located between 1/4” - 5/16” (6 and 8 mm) below the top of the counter to provide the correct
transmitter to receiver spacing. In most cases, this will require milling a cavity into the underside of the counter into which
the charger can be mounted to achieve the correct spacing.
FABTIPS: Avoid putting transmitter near locations where the device being charged may get wet, exposed to
heat or other conditions which may damage charging device.
After the pocket is milled out, test-fit the charger and verify that there will be clearance for the power and USB connections.
Testing the Charger:
Before installing the transmitter, verify its functionality:
1. Apply power and check to see that the green LED blinks once.
2. Place a 1/4”- 3/8” (6 to 10 mm) spacer above the charger coils: - spacer can be made of any non-metallic material
desired, e.g.: plastic, wood, cardboard, etc.
3. Place a compatible handheld device over the spacer and verify that the device indicates charging has commenced.
FABTIPS: Never place a receiver in direct contact with the transmitter coil. The minimum allowable spacing is
1/4” (6mm). Placement closer than this could damage the receiving device and must be avoided at all times.
Once installed, this concern is eliminated, but the installer must take this concern into account when testing
the device prior to installation.
