Installation
The Harmonica must be installed in a suitable environment and properly connected to its
voltage supplies and the motor.
3.1. Before You Begin
3.1.1. Site Requirements
You can guarantee the safe operation of the Harmonica by ensuring that it is installed in an
appropriate environment.
Feature Value
Ambient operating temperature 0 °C to 40 °C (32 °F to 104 °F)
Maximum operating altitude 2,000 m (6562 feet)
