Installing the Cisco LoRaWAN Interface Module
Powering the Cisco LoRaWAN Interface Module
Warning: A readily accessible two-poled disconnect device must be incorporated in the fixed wiring.
Statement 1022
Warning: Connect the unit only to DC power source that complies with the safety extra-low voltage (SELV)
requirements in IEC 60950 based safety standards. Statement 1033
To connect a DC power cable, you need to supply these tools and material:
 Shielded outdoor-rated and twisted pair (min 5 tpf) DC power cable (minimum 22 AWG and maximum 16 AWG to
fit the DC plug, and big enough to compensate the loss for length or heat) with outside cable diameter of 4.3 mm to
6.5 mm
 Adjustable or open-end wrench
 Small flat screw driver
 Two-pin DC power connector (PLG-PWRJCK=, Cisco supplied)
To connect the DC power cable to the Cisco LoRaWAN Interface Module, follow these steps:
1. Before connecting DC power to the Cisco LoRaWAN Interface Module, ensure that the ground is connected to the
Cisco LoRaWAN Interface Module (see Grounding the Device).
2. Turn off all power sources to the Cisco LoRaWAN Interface Module, including the DC power source.
Warning: This unit might have more than one power supply connection. All connections must be removed to
de-energize the unit. Statement 1028
Caution: When installing DC power to the Cisco LoRaWAN Interface Module, always connect the device end of the
cable FIRST. When removing the DC power connector, always disconnect the device end of the cable LAST.
3. Use a large Phillips or Flat Blade screw driver to remove the DC power connector plug from the Cisco LoRaWAN
Interface Module. Do not discard plug and rubber seal unless you are certain that the port will not have to be
re-plugged. (see Figure 11 on page 35 for the location of the DC power connector).
