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.
To mount the device, proceed as follows:
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.
Fig. 3: Wall mounting: pulling off the attachment
2. 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 it off with a screwdriver or a
similar hard object. This will damage the device.
