General This manual provides instructions on how to install and configure the nWGT, part of Orpak's Wireless Forecourt Payment Solution. 1.2. Product Description nWGT units are installed in the forecourt, typically one per dispenser, and create the forecourt mesh wireless network that covers the entire station. Each of the forecourt devices (dispensers, OPTs, printers) is physically connected to the nWGT unit. The unit can be also installed anywhere in the island, on a wall, or on a pole. The Wireless Forecourt network is based on mesh network topology uses IEEE 802.15.4 replacing the cable infrastructure and provides full and robust wireless coverage throughout the station forecourt between the FCC / POS (through the CnWGT) and the dispensers and other forecourt devices. The wireless network is encrypted by AES-128 to provide high security for the data over the air. The CnWGT is the access point to the wireless network from the station office. This unit is typically connected to the FCC (or POS) using LAN to provide the access between the FCC / POS and the forecourt devices for authorization and service. The nWGT can be operated as a converter unit, from wireless network to serial channels, such as RS485 or with an add-on dispenser interface. 1.2.1. Wireless Forecourt Wire infrastructure at a gas stations forecourt increases the cost of automating existing stations or building new ones and the TCO for the oil company and station owners. Orpak offers a solution for a fully wireless forecourt connecting the controller and the dispensers via Orpak's highly robust wireless network. The Wireless Forecourt is specially designed for the gas station environment and uses unlicensed frequency band in mesh configuration with strong redundancy and encryption. 1.3.

CAUTION:Installation inside of a dispenser is not recommended by Orpak, and must be performed in compliance with all standards, precautions, and guidelines detailed Preliminary Considerations. 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 26 nWGT Installation Manual Use a pneumatic (non-electric) drill for all necessary drilling If no pneumatic drill is available, remove the section of the dispenser where the nWGT will be installed, and perform the installation offsite in a safe location away from fire hazards A.3. In-Dispenser Installation CAUTION:Verify that the dispenser head enclosure is not made completely of metal as it will block the RF transmissions. Ensure that there exists a gap of non-metal material to allow transmissions to reach outside the dispenser head. The nWGT unit is installed inside a dispenser with a bracket, and it can be installed in either a vertical position (for bracket installation details, Top-Mounted Bracket Installation) or a horizontal position (for bracket installation details, see section Wall-Mounted Bracket Installation).

Users (all parties involved in designing, preparing, or implementing the nWGT installation process, and excludes Orpak and any party representing Orpak) are responsible for following all guidelines and regulations regarding the installation conditions, including those which apply to other products installed in the gas station (whether Orpaks or not). Installation of the nWGT in/on a dispenser is prohibited unless the dispensers manufacturer written permission to do so was received in advance. In no event shall Orpak be liable for any damage caused to the pump, dispenser, or any internal components due to improper compliance with this manual or the manual of any related products. Any direct, indirect, or incidental damages are the sole responsibility of the user. CAUTION:Installation inside of a dispenser is not recommended by Orpak, and must be performed in compliance with all standards, precautions, and guidelines detailed Preliminary Considerations. B.2. In-Dispenser Installation Guidelines When installing the nWGT on a dispenser, follow all relevant guidelines from the dispenser manufacturer. Guidelines may vary according to dispenser model and manufacturer Use a pneumatic (non-electric) drill for all necessary drilling If no pneumatic drill is available, remove the section of the dispenser where the nWGT will be installed, and perform the installation offsite in a safe location away from fire hazards B.2.1. Damage Prevention If the installation requires drilling a hole in the dispenser, use a dedicated protective conduit for each cable bundle to ensure that the installation is completely watertight (see section Cable Gland and Conduit Installation). This will prevent damage to the dispenser and its internal components from water or other external elements. 1. Install an explosion proof gland in the drilled hole 2. Use protective tubing to cover the cable bundle from the nWGT to the dispenser unit Note: If possible within model/manufacturer guidelines, drill a hole in the side of the dispenser rather than on top. When connecting between the nWGT and the dispenser, position the cable tubing such that any water from rain or condensation will flow towards the ground and not towards the opening in the dispenser. nWGT Installation Manual 29 3. Use watertight sealing washers (neo bonded galvanized washers) to install the nWGT on the dispenser (see Figure B-1):
Figure B-1 - Sealing Washer Example B.3. Top-Mounted Bracket Installation To install the nWGT on top of a dispenser in an upright position using a bracket, proceed as follows:
