CAUTION! | Risks when rack mounting the transmitter! | ||
| When installing the device in a closed or | ||
| operation, the ambient temperature, the mechanical loading and the electrical potentials will | ||
| be different from those of devices which are not mounted into a rack. | ||
Make sure that the ambient temperature within the rack does not exceed the permissible temperature limit specified in the SR 300 IEM G3 specifications. If necessary, provide additional ventilation.
Make sure that the mechanical loading of the rack is even.
When connecting to the power supply, observe the information indicated on the type plate. Avoid circuit overloading. If necessary, provide overcurrent protection.
When rack mounting, please note that intrinsically harmless leakage currents of the individual mains units may accumulate, thereby exceeding the allowable limit value. As a remedy, ground the rack via an additional ground connection.
Rack mounting one Secure the rack mount “ears” 
of the supplied GA 3 rack adapter to the transmitter as
transmitter described on page 9.
Secure the blanking plate 
to one of the rack mount “ears” using two recessed head screws (M 6x10) (see diagram).
Connect the antenna. You have the following options:
– You can connect the supplied rod antenna to the | rear of the transmitter |
(see page 9). In this case, insert the two blanking plugs | into the holes of the |
blanking plate. |
|
–You can use the AM 2 antenna front mount kit (optional accessory) and mount the rod antenna to the blanking plate 
.
–You can use a remote antenna, if necessary in conjunction with the AC 3 antenna combiner.
Slide the transmitter with the mounted blanking plate 
into the 19” rack.
Secure the rack mount “ear” 
and the blanking plate 
to the 19” rack.
