A.2. In-Dispenser Installation Guidelines
For in-dispenser nWGT installations, adhere to the following guidelines:
When installing the nWGT in a dispenser, follow all relevant guidelines from the dispenser
manufacturer. Guidelines may vary according to dispenser model and manufacturer.
Install the nWGT in a vacant area within the dispenser head; make sure it is at least 25x25cm
In cases where the nWGT functions as the Master nWGT, it should be connected to the FCC
controller using shielded S-CAT5E LAN or an RS485 cable. Install the master nWGT as close as
possible to the FCC controller
Verify that the dispenser head enclosure is not made completely of metal as it will block the RF
transmissions
For ease of maintenance, it is recommended not to install the nWGT higher than two meters from
the ground. However, the higher will be the unit; the better will be the RF coverage
The installation procedures must meet all safety measures according to local state regulations
Locate a 110-240 VAC power source for the nWGT's power supply
Prior to installation procedures turn off all dispenser head (CPU) power sources
UL listed nWGT boxes are provided with provisions for conduit connection allowing using UL
approved tubes for power lines. The conduits grips/fittings are not sufficient for this purpose
For non-UL nWGT, couplers are provided for the power and data holes
