Section 3 – Configuring for 19" rack mount
TOELLNER Electronic Instrumente GmbH
3.2 19" adapter set (2 HU) for two Toellner Instruments ½ 19" (option)
The series TOE 9261 Electronic Switches are 19" rack-compatible tabletop devices. By
using the optional TOE 9522 two Toellner Instruments ½ 19" (2 HU) of equal length can be
easily converted for 19" 2 HU rack mount.
The optional 19" adapter set TOE 9522 includes two 19" adapter pieces with handle, a front
connecting profile, and a rear connecting profile as well as the necessary installation
materials (see diagrams on the following page).
Reconfiguring from two Toellner Instruments ½ 19" to 19" rack mount
1. Use the included TX 20 screwdriver to remove the feet from the two devices. First remove
the rubber inserts on the front feet.
2. Use the included Allen wrench to remove the two inner screws (6) on the left and right
side of the front panel of each device. Pull the four fill strips (5) from the side.
3. For the outer faces of the devices attach a handle (4) to a 19” adapter piece (1) each
using the countersunk screws (7). Insert these units in replacement for the fill strips and
screw them on to the front panels using the hexagon socket screws (6).
4. In the center insert the front connecting profile (2) in replacement for the fill strips and
screw it on to the front panels using the hexagon socket screws (6).
5. Use the Allen wrench to remove the inner mounting screw (6) of each housing at the rear
of the two devices.
