1 Description
The R&S ZZA-GE23 Rack Adapter 2HU is designed for installing units of the suppor-
ted instruments in 19 inch systems. The dimensions of the rackmount kits are designed
according to the 19 inch standard DIN 60297-3-101.
For the installation of the racks in 19 inch cabinets, rails must be used.
The R&S ZZA-GE23 Rack Adapter 2HU is supplied without front handles. However, it
can be retrofitted at any time with handles. Thus, you can define the look of the han-
dles individually according to your wishes. You can use all standard handle bars with
55 mm spacing and M4 thread. The outer dimensions should not exceed 65 mm. For
the assembly of the handles, use M4x10 countersunk screws.
Suitable examples:
●Ganter handle GN 425.6-8-55-EL (available from Ganter)
●Rohde & Schwarz handle series ST, ST 08.055.22 (available from
Rohde & Schwarz, Ettinger, .....)
All necessary screws for mounting are included.
Shipping of instruments built in to the rack is not permitted.

Risk of instrument damage due to insufficient airflow in a rack
If the instrument is run with insufficient airflow for a longer period, the instrument over-
heats, which can disturb the operation or cause the instrument to shut down.
To avoid overheating, make sure that the air can circulate through the instruments.
Reserve enough space on the outsides (at least 10 cm) to ensure sufficient cooling.
To install the instrument:
1. Place the instrument with the bottom feet position facing up.
2. Loosen the four screws at the rear panel partially and slide the two rear brackets
over the screws position.
3. Tighten the four screws back partially so that mounting of the lower cover can be
adjusted for step 5.
4. Mount the lower cover over the two rear brackets and tighten the four screws on
the lower cover.
5. Tighten the four screws back at the two rear brackets.
