If you decide to no longer use a device, it is recommended to make it inoperable by unplugging it from the mains.
Make sure it is switched off electrically (both polarities), disconnecting the conductors from the contact points of the mains by opening
the omnipolar switch with at least 3 mm between the contacts.
Assembly of the instrument
All instruments produced are normally supplied already assembled. For wall installation see paragraph “Wall assembly”.
Disassembly of the instrument
Always pay the utmost attention when disassembling the instrument or before performing maintenance on it. Always disable
electrical connections beforehand.
