Installation
Mechanical
The device must be installed in a location that is sufficiently ventilated so that there is no risk of internal
heating. Place the device against a flat, firm and stable surface. It is not recommendable to install the radio
modem on a strongly vibrating surface. Suitable dampening and/or isolation materials should be used in
cases where the installation surface will be subjected to vibration.
Electrical (wiring)
To prevent damage both the radio modem and any terminal devices must always be switched OFF before
connecting or disconnecting the serial connection cable. It should be ascertained that different devices used
have the same ground potential. Before connecting any power cables the output voltage of the power supply
should be checked.
The product has no disconnecting device. An external disconnecting device must be installed. This must be
close to the equipment.
