Ground Cable Installation

The Kona Macro Ex Gateway requires a permanently connected Protective Earth (PE) Ground conductor. The Protective Earth Ground connection is made through a double hole lug to the termination point located on the side of the enclosure as illustrated in Figure 8. The cable lug must have 6.35 mm ø holes on 16 mm centers (0.25” ø on 0.63” centers). The required ground cable gauge is #10 AWG (4 mm2) minimum. This ground connection to earth is always required.
The Kona Macro Ex Gateway grounding system shall follow local and national electrical codes. The Protective Earth Ground conductor terminated at the double hole lug point is mandatory and must be the first connection made to the Gateway during installation. Proper routing and termination of this cable is key to robust lightning withstand performance; in high susceptibility installations, every effort shall be made to minimize connection inductance and ground bed resistance.

The ground cable installation steps are as follows:

1. If required, lightly abrade the surface of the lug grounding surface with a fine wire brush to remove any oxide layer
2. Use a clean cloth to remove any debris from this surface.
3. Immediately coat the contact surface with a thin layer of anti-oxidant compound.
4. Install the ground cable through its double hole lug onto the chassis ground point using the two supplied M6 x 1.0 – 16 mm bolts with flat and star lock washers, torqued to 10.4 Nm (7.7 ft·lbs) (see Figure 9).

LoRa RF Antenna Connection
The LoRa RF antenna connects through a cable to an N-Type female connector located on the bulkhead of the Gateway. The LoRa RF connector center conductor and shield are grounded to earth through the Gateway’s earth ground connection. The system designer must take note of this when installing the Gateway in accordance with standards such as IEC 60079-14. The Gateway LoRa RF antenna port is a 50 Ω RF system, the RF cable and antenna connected shall have a 50 Ω nominal impedance.

The Gateway LoRa RF antenna port is a grounded intrinsically safe circuit. This allows for the use of a standard antenna upon assessment as simple apparatus by a qualified person. Antennas supplied by TEKTELIC for the Macro Ex Gateway have already been assessed as simple apparatus. The LoRa antenna gain must be limited to 6 dBi to meet EIRP limit requirements of Clause 6.6.2 of CSA/UL 60079-0. Torque the mating N-type RF cable connector to 2.0 Nm (1.5 ft·lbs). Although the N-Type bulkhead connectors on the Gateway provide the rated ingress protection, the mating cable connector is likely not water proof and must be taped to provide protection for the cable. TEKTELIC recommends taping with Scotch Wireless Weatherproofing Kit, WK-101. Follow the taping procedures outlined by the supplier of this tape system.

Cellular RF Antenna Connections
The Kona Macro Ex Gateway supports connection to a main and a diversity cellular RF antenna when factory configured. The cellular antennas attach through cables to the N-Type connectors located on the bulkhead of the Gateway. The cellular RF connector center conductors and shields are grounded to earth through the Gateway’s Earth Ground connection. The system designer must take note of this when installing the Gateway in accordance with standards such as IEC 60079-14. The Gateway cellular RF antenna ports are a 50 Ω RF system, the RF cables and antennas connected shall have a 50 Ω nominal impedance. The Gateway’s cellular RF antenna ports are grounded intrinsically safe circuits. This allows for the use of standard antennas upon assessment as simple apparatus by a qualified person. Antennas supplied by TEKTELIC for the Macro Ex Gateway have already been assessed as simple apparatus. The cellular antenna gain must be limited to 2 dBi to meet EIRP limit requirements of Clause 6.6.2 of CSA/UL 60079-0. Torque the mating N-type RF cable connector to 2.0 Nm (1.5 ft·lbs). Although the N-Type bulkhead connectors on the Gateway provide the rated ingress protection, the mating cable connector is likely not water proof and must be taped to provide protection for the cable. TEKTELIC recommends taping with Scotch Wireless Weatherproofing Kit, WK-101. Follow the taping procedures outlined by the supplier of this tape system. For systems which do not have cellular backhaul, the bulkhead RF transit connectors are replaced with approved stopping plugs.

GPS RF Antenna Connection

The GPS antenna attaches through a cable to the N-Type female connector located on the bulkhead of the Gateway. The GPS RF connector center conductor and shield are grounded to earth through the Gateway’s earth ground connection. The system designer must take note of this when installing the Gateway in accordance with standards such as IEC 60079-14. The Gateway GPS RF antenna port is a 50 Ω RF system, the RF cable and antenna connected shall have a 50 Ω nominal impedance. The Gateway’s GPS antenna port is a grounded intrinsically safe circuit. This allows for the use of a standard antenna upon assessment as simple apparatus by a qualified person. Antennas supplied by TEKTELIC for the Macro Ex Gateway have already been assessed as simple apparatus. The GPS connection requires a passive antenna and therefore the cable length should be kept as short as possible to minimize RF power loss. Torque the mating N-type RF cable connector to 2.0 Nm (1.5 ft·lbs). Although the N-Type bulkhead connectors on the Gateway provide the rated ingress protection, the mating cable connector is likely not water proof and must be taped to provide protection for the cable. TEKTELIC recommends taping with Scotch Wireless Weatherproofing Kit, WK-101. Follow the taping procedures outlined by the supplier of this tape system.

Opening and Closing the Enclosure
Refer to Section 2.1 Safety Precautions for important safety information. It is important to take care to not damage the enclosure flame path flanges or the environmental gasket, located in a channel on the enclosure flange, when opening the enclosure, while working on the open enclosure, and when closing the enclosure. It is not allowed to repair the flame path. To open the enclosure, fully loosen and remove all 16 cover screws, taking care to store all of the fastening hardware for reuse. It is advisable to remove last a screw near the top center of the enclosure while supporting the cover, as it is heavy and may fall open unexpectedly once all screws are removed. Store each screw along with its lock washer and flat washer for reuse when closing the enclosure. The cover is hinged along the bottom edge; once the screws are disengaged, lower the cover carefully to its open position, where it will be held by built-in stops. Handle the cover with caution to ensure a controlled lowering process. To help facilitate opening a cover which does not separate freely from the enclosure body, a pry feature is located top center of the cover as illustrated in Figure 10. Care must be taken to ensure no tool contact outside of the pry feature area.

Before closing the enclosure cover:

inspect the enclosure flame path on the base and cover flanges for any dirt or other foreign objects and clean with a soft cloth if necessary inspect the enclosure flame path on the base and cover flanges for any damage (note that it is not allowed to repair the flame path), the base of the enclosure implements stainless steel thread inserts for receiving the cover screws, inspect the cover screw receiving holes to ensure that the thread inserts are still in place and are not protruding above the flange surface, inspect the gasket on the cover flange for any damage and ensure it remains securely seated in  its proper location.

For improved resistance to corrosion, a corrosion inhibiting, non-hardening, and non-evaporative silicone grease may be applied to the flame path (flange). The recommended grease is Loctite LB 8104 or Loxeal No. 9.

To close the enclosure, rotate the cover up and into place while ensuring that all cables between the cover and the enclosure body are neatly routed and not bent or stressed and are not pinched  between the cover and the enclosure body. Once the cover is in place and its flange is fully flush with the enclosure body flange, install all 16 of the Gateway cover screws, each with its lock washer and flat washer as illustrated in Figure 11. The Gateway cover screws shall have a minimum property class of A4-70. Torque each screw to 48 Nm (35.4 ft-lb) using a 10 mm hex bit while following a star pattern order  similar to that illustrated in Figure 12. It is recommended to perform two or three passes in this  pattern, each with increasing torque, ending at the recommended torque.

Cable Entry
Two threaded entries are provided to facilitate DC power and Ethernet entry into the Gateway enclosure. Depending on the factory ordered configuration these entries may be M25 x 1.5 or ¾” NPT thread type. Always confirm the thread type by checking the printed information next to the entry hole. The Gateway is shipped with one entry covered with a temporary disposable plastic plug and a second entry closed with an approved stopping plug. Always use first the entry closed with the temporary disposable plastic plug. The second entry closed with the approved stopping plug can be used when both DC power and Ethernet are required. Either entry may be used as long as the unused entry is blocked using the approved stopping plug. Cable selection and provisioning along with required entry hardware such as cable glands, adapters, and conduit fittings are to be site selected and provided. All cables and hardware shall be suitably approved and shall be in compliance with NFPA 70, National Electrical Code, CSA C22.1, Canadian Electrical Code, or IEC 60079-14 requirements, providing and maintaining a degree of protection of at least IP66.

Typical cable entry configurations are:

• DC Power with cellular backhaul, where only one threaded entry is used.
• Ethernet with PoE, where only one threaded entry is used.
• DC Power with Ethernet backhaul, where both threaded entries are used.

If a DC power feed is installed into the enclosure, the DC power conductors are terminated at the copper interface board connector J1. If an Ethernet feed is installed into the enclosure, the Ethernet  pairs are terminated at the copper interface board connector J2. In addition, the copper interface board connector J1 allows for the termination of up to two ground bonding conductors. Note that the external double hole lug ground point must be used for the Gateway protective earth ground termination, the internal ground terminations may be used for additional interface bonding, such as for cable drain wires.

Internal Interfaces
Figure 13 details the internal interfaces for the Kona Macro Ex Gateway. The only internal user connections available are for DC Power, Ethernet, and auxiliary ground bonding. All other internal connections are factory made and may be repaired but are not to be altered.

Table 2-2 summarizes the Gateway internal interface connection specifications.

Table 2-2: Kona Macro Ex Gateway Internal Connection Specifications

The J1 ground terminals are bonded to the Gateway enclosure and may be used for terminating a npower feed ground conductor or a cable shield drain wire from either of the DC power or Ethernet cables. Note that the specified external connection to the enclosure double hole lug ground termination point is always required even if a ground wire is provisioned with one of the entry cables.

An ANSI/TIA-568, T568B standard RJ-45 receptacle J3 is also provided as an alternate Ethernet termination point from the J2 terminal block. Only one of these connectors may be used concurrently as they are wired together on the PCB. The J2 terminal block is intended for a permanent robust Ethernet connection whereas the J3 RJ-45 receptacle is intended for convenience with local configuration and test activities.
