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.
To by supplied by class II (LPS) certified AC/DC adaptor.
