PRT-4G-USB | Protege DINRail Cellular Modem | Installation Manual 3
Introduction
This installation manual provides instructions and technical specifications for physical installation of the Protege
DINRail Cellular Modem. For programming and operating information, see the Protege DINRail Cellular Modem
Configuration Guide, available from the ICT website.
About This Module
The Protege DINRail Cellular Modem is a cellular communication device that provides a convenient wireless
connection for a Protege controller.
For Protege WX controllers this device can provide wireless IPalarm transmission capability, allowing
communication of alarms from a controller to a monitoring station via cellular network transmission for
convenient, cost-effective monitored outbound reporting.
Controller Cellular Modem Cellular Network
Protege GX System
Monitoring Station
For Protege GX controllers this device can provide wireless IPalarm transmission capability, and on supported
networks can also facilitate programming downloads and manual control from the Protege GX system, and event
uploads to the Protege GX events database.
With no physical network required this is an ideal solution for remote sites and installations where network
infrastructure may be unavailable, or difficult and expensive to install.
The current features of the DINRail Cellular Modem include:
⦁Category M-1cellular network capability with fallback to 2GGSM
⦁Secure encrypted communications via the Report IPservice
⦁Continuous connection detection and automatic fail reset
⦁1 LEDindicator
⦁1 Micro-SIM card holder
⦁1 SMAantenna connection
⦁1 USB-C port
⦁1 4Gantenna (included)
⦁1 USB-A to USB-C connector cable (included)
⦁Industry standard DIN rail mounting
⦁Convenient 1/4 DINfootprint
Controller Hardware
Only controllers equipped with a USBport are capable of communicating with the cellular modem.
If it is not practical to physically check each controller for a USBport, contact ICT Technical Support with a list of
the controller serial numbers.

Grounding Requirements
An effectively grounded product is one that is intentionally connected to earth ground through a ground
connection or connections of sufficiently low impedance and having sufficient current-carrying capacity to
prevent elevated voltages which may result in undue hazard to connected equipment or to persons.
Grounding of the Protege system is done for three basic reasons:
1. Safety
2. Component protection
3. Noise reduction
Safety Grounding
The object of safety grounding is to ensure that all metalwork is at the same ground (or earth) potential.
Impedance between the Protege system and the building scheme ground must conform to the requirements of
national and local industrial safety regulations or electrical codes. These will vary based on country, type of
distribution system and other factors. The integrity of all ground connections should be checked periodically.
General safety dictates that all metal parts are connected to earth with separate copper wire or wires of the
appropriate gauge.
Earth Ground Connection
The DIN rail enclosure and the DIN rail modules must be grounded to a suitable single-point earth ground
connection in the installation. A minimum 14AWG solid copper wire (or thicker, in accordance with local
authorities) shall be used from the Protege system's earth connection points.
The DIN rail enclosure includes an earth ground single-point link connection via the metallic enclosure. This single-
point link is the Protege system's earth ground. All modules that have earth ground connections and that are
installed in the same enclosure shall be connected to this single point. A single-point earth ground connection
avoids the creation of ground loops in the system and provides a single reference point to earth ground.

Mounting
Protege DIN rail modules are designed to mount on standard DIN rail either in dedicated DIN cabinets or on
generic DIN rail mounting strip.
When installing a DIN rail module, ensure that there is adequate clearance around all sides of the device and that
air flow to the vents of the unit is not restricted. It is recommended that you install the module in a location that
will facilitate easy access for wiring. It is also recommended that the module is installed in an electrical room,
communication equipment room, secure cabinet, or in an accessible area of the ceiling.
1. Position the DIN rail module with the labeling in the correct orientation.
2. Hook the mounting tabs (opposite the tab clip) under the edge of the DIN rail.
3. Push the DIN rail module against the mount until the tab clips over the rail.
Removal
A Protege DIN rail module can be removed from the DIN rail mount using the following steps:
1. Insert a flat blade screwdriver into the hole in the module tab clip.
2. Lever the tab outwards and rotate the unit off the DIN rail mount.

The modem is not isolated and power may be supplied by the controller, another module, or a separate 12V DC
power supply. If supplied from a separate power supply the ground reference must be connected.
The SIM, antenna and USB connector cable should be installed before power is applied.
USBConnection
The cellular modem is connected to the system via USBconnection to a Protege GX or Protege WX controller.
Protege controllers which do not have a physical USBport are incompatible and cannot be retrofitted.

AUSB-A to USB-C connector cable is supplied with the cellular modem, however any compatible cable may be
used for connection. Connect the USB-A end of the cable to the USBport of the Protege controller, and the USB-C
end of the cable to the USB port of the cellular modem.

Antenna Connection
The Protege DINRail Cellular Modem requires connection of a suitable 4Gantenna.
An antenna is supplied with the cellular modem. While other antennas may be compatible only the supplied
antenna is supported, and is recommended to ensure optimum performance.
Connect the antenna cable to the screw coupling of the cellular modem's SMAcoaxial connector.

SMA Antenna Connection
The supplied antenna has a magnetic base for mounting, and should be positioned in an area covered by the
LTEsignal with Cat-M1 support.
The antenna must not be installed inside any metal enclosure or behind any metal barriers.
SIM
A SIM is required from a validated cellular network provider in the region where the Protege DINRail Cellular
Modem is installed. For a list of validated network providers for each region, please contact ICT Technical Support.
Only validated cellular networks are supported. Others may not work correctly and will not be supported by ICT.
Insert the SIM securely and fully into the cellular modem's Micro-SIMcard slot, with the metal contact facing down
and the notched corner inwards.
Never insert or remove the SIM while the modem is powered up.
