Putting the receiver into operation

Mounting the receiver into a 19” rack

Rack mounting one

receiver

왘 Secure the rack mount “ears”  (supplied with the GA 3 rack adapter) to the receiver as

described on page 8.

왘 Secure the blanking plate to one of the rack mount “ears”  using two recessed head

screws (M 6x10) (see left-hand diagram).

왘 Connect the antennas. There are two ways to connect the antennas:

– You can connect the rod antennas  to the rear of the receiver (see page 9). In this

case, insert the two blanking plugs into the holes of the blanking plate (see left-

hand diagram).

– You can use the AM 2 antenna front mount kit (optional accessory) and mount the rod

antennas to the front of the receiver (see right-hand diagram).

왘 Slide the receiver with the mounted blanking plate into the 19” rack.

왘 Secure the rack mount “ears”  and the blanking plate to the 19” rack.

왘 Align the antennas in a V-shape.

Do not fit the device feet when mounting the receiver into a 19” rack.

CAUTION! Risks when rack mounting the receiver!

When installing the device in a closed or multi-rack assembly, please consider that, during

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.

왘 Make sure that the ambient temperature within the rack does not exceed the permissible

temperature limit specified in the EM 100 G3 specifications.

왘 Ensure sufficient ventilation; if necessary, provide additional ventilation.

왘 When connecting to the power supply, observe the information indicated on the type

plate. Avoid circuit overloading. If necessary, provide overcurrent protection.

왘 When rack mounting, please note that intrinsically harmless leakage currents of the indi-

vidual mains units may accumulate, thereby exceeding the allowable limit value. As a

remedy, ground the rack via an additional ground connection.



When using more than one receiver, we recommend connecting remote antennas

and, if necessary, using Sennheiser antenna accessories. For more information, visit
