low-voltage conduit.
– Low-voltage and 100 … 240 V conduits must not be installed together in a
flush-mounted box!
6.1 Requirements for the electrician
Danger - Electric voltage!
Install the device only if you have the necessary electrical engineering
knowledge and experience.
■Incorrect installation endangers your life and that of the user of the electrical

6.2 Mounting/dismantling
Danger - Electric voltage!
Risk of death and fire due to electric voltage of 100 to 240 V.
– Work on the 100 - 240 V supply system may only be performed by
authorised and qualified electricians.
– Disconnect the mains voltage prior to mounting and dismantling.
Caution! The device can sustain damage when coming into contact with
hard objects!
The plastic parts of the device are sensitive.
– Pull the attachment off only with your hands.
– Do not lever parts off with screwdrivers or similar hard objects.
In Germany the flush-mounted insert must only be installed in flush-mounted boxes according to
DIN 49073-1, Part 1, or suitable surface-mounted housings.
Different installation standards apply in other countries. These are to be taken into account
when used in connection with a different support ring and flush-mounted box.
1. Pull the attachment off.
– If the device is already mounted
or assembled, pull off the
attachment from the flush-
mounted insert with the aid of the
frame.

– If the device is in its as-delivered
state, pull the attachment off the
flush-mounted insert with your hands.
– Pull the attachment off only with your
hands. Do not lever parts off with
screwdrivers or similar hard objects.
This will damage the device.
– When pulling off, first the resistance
of the plastic clamps must be
overcome.
