Installing the SR IEM G4 in a rack

NOTICE

Rack mounting poses risks

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.

Make sure that the ambient temperature within the rack does not exceed the permissible temperature limit specified in the specifications. See Specifications.

Ensure sufficient ventilation; if necessary, provide additional ventilation.

Make sure that the mechanical loading of the rack is even.

When connecting to the power supply system, 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 power supply units may accumulate, thereby exceeding the allowable limit value. As a remedy, ground the rack via an additional ground connection.

To mount the transmitter in a rack, you will need the GA 3 rack mounting kit Rack mount kit (optional accessory).

Mounting a single transmitter in a rack

Unscrew and remove the two recessed head screws (M4x8) on each side of the transmitter.
Secure the left and right mounting angles to the sides of the transmitter using the previously removed recessed head screws.
Secure the blanking plate to one of the mounting angles using two recessed head screws (M6x10).
Attach the antenna. You have the following options:
- Connect the supplied rod antenna on the rear side of the transmitter. In this case, cover the antenna holes with the two covers (left diagram).
- Attach the AM 2 antenna front mounting set (optional accessory) and mount the rod antenna on the blanking plate (right diagram).
- Use a remote antenna, possibly in combination with the AC 41 antenna combiner.
If you are using more than one transmitter, we recommend using remote antennas and, as needed, Sennheiser antenna accessories. For more information, visit the ew G4 product page at sennheiser.com.
Slide the transmitter with the mounted blanking plate into the 19" rack.
Secure the mounting angle and the blanking plate to the 19" rack.
Align the mounted antennas in a V-shape.

Mounting two receivers side by side in a rack

If you want to mount two transmitters side by side, you can mount the antennas to the front of the rack in combination with the AC 41 antenna combiner. Otherwise, you can use the ASA 1 antenna splitter in combination with the Antenna front mounting kit front mounting kit and an additional Rack mount kit rack mounting kit. For more information, visit the ew G4 product pages at sennheiser.com.

Place both transmitters upside down and side by side on an even surface.
Secure the jointing plate to the transmitters using the six recessed head screws (M3x6).
Secure the mounting angle.
Slide the connected transmitters into a 19" rack.
Secure the mounting angle to the 19" rack.
