Installation

Safety Precautions

• Installation, operation, and maintenance of the IotaComm Dual-Band Gateway must only be performed by a professionally trained service technician who is aware of all hazards involved.

• The IotaComm Dual-Band Gateway must be installed in a restricted access location (such that touching of the Gateway by non-service persons is not likely).

• The IotaComm Dual-Band Gateway may become hot to the touch during normal operation at elevated ambient temperatures. The surface temperature of the Gateway may reach 90°C.

• The IotaComm Dual-Band Gateway has no internal field serviceable parts. The Gateway module must only be opened by an approved TEKTELIC service center.

• All installation practices must be in accordance with the local and national electrical codes.

• Do not work on the system during periods of lightning activity.

• The IotaComm Dual-Band Gateway is considered permanently connected equipment. The Protective Earth Ground connection (that is, the two-hole lug to chassis ground) is always required.

• Ensure the IotaComm Dual-Band Gateway Protective Earth Ground connection is properly terminated prior to the connection of any other interfaces.

• The IotaComm Dual-Band Gateway contains primary lightning surge suppression on the Direct DC power port, the Copper Ethernet port, the GPS antenna port and the LoRa RF antenna ports. The primary lightning protectors have the ability to bridge the interface isolation boundary during over-voltages. Ensure that the Protective Earth Ground connection is always in place.

• Ensure that the IotaComm Dual-Band Gateway, its antennas and supporting structures are properly secured to eliminate any physical hazard to people or property. The Gateway must be securely mounted according to the mounting instructions prior to any cable connection and operation.

• The IotaComm Dual-Band Gateway does not contain a power supply disconnection device; a readily accessible disconnection device must be incorporated external to the IotaComm Dual-Band Gateway.

• The direct DC powered IotaComm Dual-Band Gateway shall be supplied through an input overcurrent protection device rated not more than 10 A. The overcurrent protection must have the appropriate current interrupt capacity for the power source and must be incorporated into the non-earthed conductor(s) of the IotaComm Dual-Band Gateway DC supply.
  For the direct DC power feed option, the DC positive pin must be at positive potential relative to the DC negative pin. If the polarity is reversed, the unit will not sustain damage but will not operate until the connection polarity is corrected.

• Although the IotaComm Dual-Band Gateway can be powered through either a direct DC input or through power over Ethernet (PoE), simultaneous application of power to both inputs may result in unexpected operation and shall be avoided.

• The IotaComm Dual-Band Gateway power source must meet SELV requirements.

Unpacking and Inspection

• The following should be considered during the unpacking of a new IotaComm Dual-Band Gateway.

1. Inspect the shipping carton and report any significant damage to TEKTELIC.
2. Unpacking should be conducted in a clean and dry location when possible.
3. Do not discard the shipping box or foam inserts as they will be required if a unit is returned for repair or re-configuration.

Required Equipment for Installation

The following tools are required to install the IotaComm Dual-Band Gateway module:

1. A 6 point metric socket set and torque wrench drive.
2. Anti-oxidant compound (NO-OX-ID, Penetrox, Noalox, Ox-Gard or equivalent).
3. A small wire brush.
4. A clean cloth.
5. Weatherproofing tape kit for the RF connectors (Scotch Wireless Weatherproofing Kit, WK-101 recommended).
6. Appropriately sized pipe clamps for pole mounting or appropriate screws or bolts (four sized M8) with any required anchors according to the wall construction for wall mounting.

IotaComm Dual-Band Gateway Mounting

• IotaComm Dual-Band Gateway is designed to be mounted to a vertical pole or wall using a mounting bracket. The mounting bracket is a single part that bolts to the back surface of the Gateway using supplied hardware (four M6x1.0 – 14 mm bolts with flat and star lock washers) as illustrated in Figure 4. The Gateway module must be oriented with the connector bulkhead facing down, towards earth.
• Ensure that the structure to which the Gateway is being mounted is secure and able to support a dead load of at least 136 kg (300 lbs). The area below must be free of any obstructions to cable ingress.

The IotaComm Dual-Band Gateway wall mounting procedure is as follows:

1. Bolt the wall mounting bracket to the Gateway module using the supplied bolts and washers.
2. Install 2 site supplied M8 bolts into the wall at 139.7 mm (5.5”) center spacing, leaving the bold heads protruding with a 2mm gap from the wall surface.
3. Hang the IotaComm Dual-Band Gateway with bracket from the two bolts by inserting the keyhole slots at the top of the bracket onto the 2 bolts and tightening the bolts.
4. Insert and tighten two additional site supplied M8 bolts through the holes at the bottom of the bracket.

The IotaComm Dual-Band Gateway pole mounting procedure is as follows:

1. Bolt the wall mounting bracket to the Gateway module using the supplied bolts and washers.
2. While temporarily supporting the Gateway with bracket, install the two site supplied pipe clamps, one through each of the upper and lower slotted clamp mounting points.

Ground Cable Installation

• The IotaComm Dual-Band Gateway is considered Permanently Connected Equipment and requires a permanently connected Protective Earth Ground (PEG) conductor. The Protective Earth Ground connection is made through a 1/4 x 0.75” on center double hole lug to the ground termination point illustrated in Figure 5. The ground cable gauge shall be #10 AWG minimum.
• The IotaComm Dual-Band 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 IotaComm Dual-Band 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. Lightly abrade the surface of the casting ground area with a fine wire brush to remove the 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 2-hole lug onto the chassis ground point using the two supplied 1/4 – 20 x 1/2” bolts with flat and star lock washers, torqued to 10.4 Nm (92 in·lbs).

Direct DC Power Cable Installation

• Depending on the model, the IotaComm Dual-Band Gateway direct DC feed may terminate at a dedicated two pin circular plastic connector (CPC), a two pin M12 circular metal connector, or at a hybrid three pin DC with optical connector. In all cases the direct DC power input is isolated from chassis (earth) except for the primary surge suppressors. One lead of the DC power feed is normally earth referenced external to the IotaComm Dual-Band Gateway (usually at the power source by convention).
• The DC power cable shall be rated for outdoor application and in accordance with local and national electrical codes.
• The CPC DC connector shall be as specified in Table 2 and shall follow the signal polarity identified in Figure 6.

RF Cable Installation

• The Gateway installation will require connection to a GPS antenna, one or two LoRa RF antennas, and optionally a 3G/4G modem antenna. The RF cables attach to the N-Type connectors on the bottom of the IotaComm Dual-Band Gateway. Torque the connectors to 1.7 to 2.3 Nm (15 to 20 in·lbs). The N-Type connector interface to a cable is not water proof and must be taped to be used outdoors. TEKTELIC recommends taping with Scotch Wireless Weatherproofing Kit, WK-101. Follow the taping procedures outlined by the supplier of this tape system.
• Note that the 3G/4G modem antenna port is not surge protected and, accordingly, the antenna must be located with the Gateway module or, if remotely located, an external surge suppressor must be provisioned.

Copper Ethernet Cable Installation

• The IotaComm Dual-Band Gateway Ethernet port may be used on a temporary basis for commissioning and maintenance or may be permanently connected for backhaul. When the port is not in use, the weatherproof protective cap must be installed. When the port is permanently connector for backhaul, a proper water-tight mating connector specified in Table 2 must be used.
• The Ethernet cable must have minimum 24 AWG conductors and shall be rated for outdoor application according to local and national electrical codes.
