Installation in a panel with self-locking nuts (screw-in
version)
See drawing “1707 product information”.
If the keypad is mounted or dismounted several times, new self-locking nuts must be used
each time.
Caution!
Exceeding the maximum permissible torque inevitably leads to the
destruction of the keypad. The keypad is no longer tight nor leak proof in
this case.
Incorrect mounting of the keypad, e.g. incorrect number of rubber washers
or without washers (see 7.2.1 Mounting sequence), may result in damages
to the keypad.

The specified overload force refers to the switches, not to the mounting
situation. For Rotary Cursor Controller it is recommended to use the screw-
in variant.

7.2.1
Mounting sequence
First of all, the rubber washers should be mounted according to the front panel thickness. No
rubber washers are necessary for a front panel thickness of 1 mm. Mount 1 rubber washer per
screw bolt for a front panel thickness of 2 mm, mount 2 rubber washers per screw bolt for a
front panel thickness of 3 mm and mount 3 rubber washers per screw bolt for a front panel
thickness of 4 mm. Since these have a slightly smaller inner diameter, they clamp lightly on
the thread of the bolt to make it more difficult for the washers to fall off. Afterwards, the keypad
has to be installed in the front panel, while the cable incl. connector has to be pushed through
the sleeve. The sleeve can be installed rotated by 180° in each case. Afterwards, the 4 washers
have to be installed over the screw bolts and fixed with the nuts. The correct tightening torque
is defined in the 1707 product information and must be observed. The last step is to connect
the plug connector.
The keypad of the screw-in version must be aligned manually to the panel. There is no
automatic centering, the keypad can be slightly pushed into the mounting panel (depending on
the opening size of the panel).
