ELECTRICAL SYSTEM
IMPORTANT!
The electric supply to the e-box must be disconnected before beginning any work inside
the box; it’s not enough to turn off the internal main switch.
Electrical box mounting position
The electrical control box must be mounted on a wall as shown below, do not mount horizontally
on the floor or in ceiling as this leads to reduced airflow with increased risk of overheated
components.
