Rack-mounting several transmitters

You can use the supplied rack mount “ears” to mount the transmitter into a 19" rack (1 U). If you wish to mount the antennas to the front of the rack, use the GA 3030-AM antenna mount (see “Accessories” on page 29).

When rack-mounting the device, please consider that, during operation, the ambient temperature within the rack may significantly rise above room temperature. However, the ambient temperature within the rack must not exceed the temperature limit specified in the specifications.

When rack-mounting the device, take good care not to affect the ventilation required for safe operation or provide additional ventilation.

When rack-mounting the device, ensure that its housing is not mechanically loaded and that it is adequately supported at the rear, e.g. for transport.

When connecting the device to the power supply, observe the information indicated on the type plate. Avoid circuit overloading. If necessary, provide overcurrent protection.

Ensure a reliable mains ground connection of the device by taking appropriate measures.

When rack-mounting the device, please note that intrinsically harmless leakage currents of the individual devices may accumulate, thereby exceeding the allowable limit value. As a remedy, ground the rack via an additional ground connection.
