Before you start with the installation please read the following indications:
- The Doortello Business ES can, together with his modular door station program,
has a IP 55 protection degree and can be installed also outside.
- If you plan an installation in a rainy environment we suggest the use of a
weather shelter or a surface mounting box with weather shelter.
- With surface mounted and pedestals installation we suggest always the use of
the integrated heating element (12 Vdc external power supply is needed). This is
also valid for the BG version.
- If a fluid gets inside the unit disconnect at once the telephone line and the
external power supply (if installed).
- The device can only be maintained by instructed specialized technicians.
- Static discharges may damage the device. Please ensure that you are grounded
before any activity with the unit.
