Important Notice

This device, like any wireless device, operates using radio signals which cannot guarantee the transmission and

reception of data in all conditions. While the delay or loss of signal is rare, you should not rely solely on any

wireless device for emergency communications or otherwise use the device in situations where the interruption of

data connectivity could lead to death, personal injury, property damage, data loss, or other loss. NetComm

Wireless accepts no responsibility for any loss or damage resulting from errors or delays in transmission or

reception, or the failure of the NTC-100 to transmit or receive such data.

Safety and Hazards

Do not connect or disconnect cables or devices to or from the USB port, SIM card tray or the terminals of 10-pin Nano-Fit™ connector in

hazardous locations such as those in which flammable gases or vapours may be present, but normally are confined within closed systems; are

prevented from accumulating by adequate ventilation; or the location is adjacent to a location from which ignitable concentrations might

occasionally be communicated.

Mounting the device

The NTC-100 can be mounted on the wall or a DIN rail by using the mounting bracket. The mounting bracket is

made from polyamide, which is a flexible material.

DIN rail mounting

The NTC-100 serial modem mounting bracket has been designed to fit a TS 35 Type-O DIN rail with a 25mm core.

Bend the mounting bracket at the bend line so that the ridges are able to ‘hold’ onto the DIN rail edges as per the

diagram below. Alternatively, if the end of the DIN rail is open, you can slide the bracket on to the rail. You also

have the option of securing the mounting bracket further by screwing it into place on the rail.

Figure 2 – DIN rail mounting

Wall mounting

Select the location where you would like to attach the NTC-100 serial modem. Attach the mounting bracket to the

chosen wall or ceiling by using the 3 screw holes (screws not included).
