EZI/STD CHARGING UNIT INSTALLATION INTRODUCTION This bulletin discusses the installation procedure for the EZI/STD Charging Unit Individual wireless charging transmitter. OVERVIEW The EZI/STD Charging Unit Individual dual-mode transmitter is compliant with PMA and WPC Qi standards. The transmitter is tuned for best performance through 8 mm (0.315") of non-conductive solid surface. Instructions for optimum placement and installation are in this bulletin. Due to the precise routing required the installation should be done in the fabrication shop prior to sheet installation. The EZI/STD Charging Unit Individual package consists of the transmitter, power cord and transformer. PMA-compliant charging rings are available separately in packs of three: one ring each of micro USB, Apple 30-pin and Apple Lightning PMA compatible receivers. The transmitter has a micro USB port for updating the rmware if necessary. A. PREPLANNING A.1. Box Contents The box will come with the transmitter and the power supply (not pictured here). A.3. Placement There are several considerations regarding proper placement of the transmitter:
Avoid putting in proximity to locations where the device being charged may get wet, exposed to excessive heat or any other conditions which may damage the device being charged. Do not install next to heat sources (such as stoves) or where heat sources are commonly used (toasters, hot plates, etc.). Stay away from edges where charging devices can be easily knocked off the surface. Work with the customer to determine convenient locations. Page 1 of 4 EZI/STD CHARGING UNIT INSTALLATION The transmitter requires a rectangular space of 82 mm x 92 mm (3.23"x 3.60") below the surface counter. Allow an extra 25 mm (1") distance to any support structure. No metal should be between the transmitter and the surface. The transmitter also requires 36 mm (1 7/16") vertical clearance measured from the top surface (24 mm (0.94") from bottom surface). Avoid placement above heat- or moisture-generating appliances such as dishwashers, warming drawers, wine refrigerators, etc. Verify cabinet/support measurements before cutting the top. There should be a support strip between the transmitter and any cutouts or the edge of the top. The transmitter does generate some heat and ideally is installed such that it shares airspace with the cabinet interior. If placing above a drawer, make sure there is sufcient clearance, including drawer contents. Install so that the transmitter will be accessible by the customer. If there is a warranty replacement the customer will need to be able to remove and replace the transmitter. Make sure the power and micro USB ports will be accessible after installation. Plan for power cable routing and mounting of the transformer. The power supply has a 1.2 m (47") DC cable, 111 mm x 51 mm x 36 mm (4.4"
x 2.0" x 1.4") transformer and 1.2 m (47") AC cable. A four-unit power supply is available separately. If more than one transmitter is installed they should be at least 150 mm (6") from each other. A.4. Marking Charging Location Discuss the options for marking the charging spot with the customer. Some may prefer a permanent mark, either a highly visible mark or a subtle mark that blends with the background. A highly visible mark may be preferred in environments where multiple users will be using the device and arent familiar with the area. Subtle or temporary markings may be more appropriate where there are a limited number of users that will become familiar with the location over time. Marking options include laser engraving or inlays for permanent marks, and stickers for temporary marks. Laser engraving will leave a slight depression and may be more difcult to clean. For high visibility markings choose a contrasting color. In commercial environments this may incorporate corporate color logos. For subtle markings a complementary color should be used. Translucent White Joint Adhesive or Joint Adhesive is often a good choice for subtle inlays. For particulate colors matching one of the particulates may work well. The uniform shape of the mark will help it stand out when viewed at close distances, but it will blend into the background at greater distances. A.5. Additional Materials and Equipment In addition to the transmitter, fabrication will require 100% silicone adhesive, denatured alcohol and a clean cloth. Using a CNC with a at-tipped end mill bit is highly recommended for accurately cutting the cavity. Some form of cable management (conduit, clips, etc.) will be necessary. B. VERIFY TRANSMITTER OPERATION B.1. Important Testing Guidance Verify the transmitter is operational before installing by plugging it in. A green LED should blink once. DO NOT TEST BY PLACING A RECEIVER IN CONTACT WITH THE TRANSMITTER. The transmitter is optimized for the installation distance, bringing the transmitter and receiver in direct contact may damage the devices. Always test with something nonmetallic of 8 mm (0.315") thickness in between the transmitter and receiver. B.2. Firmware Updates When there is a rmware update, Neosen Energy will make the update available for download. The transmitter is updated by connecting the device to a computer using a USB 2.0 Micro Type-B to USB Standard Type-A cable. C. SHEET PREPARATION C.1. Optional Inlay/Laser Engraving Charging location marking methods that require fabrication should be performed before milling the pocket for the transmitter. Standard techniques for engraving or creating inlays may be used to identify the charging location. If the customer does not desire a permanent indicator a temporary sticker may be used and may be applied when fabrication is complete. C.2. Milling Pocket The wireless power transmitter is optimized for a surface thickness of 8 mm
(0.315"). A CNC is highly recommended for pocket milling as the distance is registered from the face of the sheet, whereas a hand router distance is registered off the back of the sheet, which may induce more variability in remaining sheet thickness. The pocket should be milled as a circle of 63.5 mm (2.5") with remaining material thickness of 8 mm (0.315"). Use a at-tipped end mill bit with a 3 mm
(0.118") radius on the tip for a uniform surface in the cavity. Make sure that once the transmitter is installed there will be clearance for attaching the power plug and that there is access to the micro USB port for potential rmware updates. D. TRANSMITTER INSTALLATION D.1. Adhering transmitter to sheet Remove all dust and shavings. Clean the sheet and ange of the transmitter with a clean cloth dampened with denatured alcohol1. Verify the desired orientation of the transmitter so that the power and USB ports will be accessible after installation. The ange will sit slightly above the surface when the coil is in contact with the cavity surface. The transmitter is attached to the sheet with a 100% silicone adhesive. Place dabs of silicone at each of the four corners. Clear or translucent adhesive is recommended, white is shown here for visibility. Avoid highly contrasting colors, particularly dark adhesive with more translucent, lighter- colored sheets. There needs to be enough silicone to ll the gap between the ange and the surface. Keep the silicone away from the coil. If for some reason the transmitter will be replaced, removal will be easier if the adhesive is only on the ange and not in the cavity. If desired, small amounts of hot melt adhesive may be placed along opposite sides to hold the transmitter in place while the silicone adhesive cures. The hot melt can be applied at the edges of the ange after the transmitter is placed in the pocket. The transmitter may be held in place with tape or a weight while the silicone cures. Hot melt adhesive is for temporary bonding only. It is not suitable for long term mounting. D.2. Wiring The transmitter is supplied with a power cord consisting of DC and AC wiring connected with a transformer. In many cases an AC power outlet may need to be installed in the cabinetry where the transmitter is to be installed. Local codes must be followed and the AC outlet often must be installed by a licensed electrician. E. LED INDICATOR The LED will indicate the current transmitter status. F. TRANSPORTATION The greatest risk of physical damage to the transmitter will be between transmitter installation and fabricated top installation in the facility. Protect the transmitter during storage and transportation. One option for protecting the transmitter is to cut a cavity large enough to contain the transmitter in a piece of stiff foam. This foam can then be taped over the transmitter for protection.
