Chapter 1:
Safety Information
In order to achieve the optimum, safe operation of the Harmonica servo drive, it is imperative
that you implement the safety procedures included in this installation guide. This information is
provided to protect you and to keep your work area safe when operating the Harmonica and
accompanying equipment.
Please read this chapter carefully before you begin the installation process.
Before you start, ensure that all system components are connected to earth ground. Electrical
safety is provided through a low-resistance earth connection.
Only qualified personnel may install, adjust, maintain and repair the servo drive. A qualified
person has the knowledge and authorization to perform tasks such as transporting, assembling,
installing, commissioning and operating motors.
The Harmonica servo drive contains electrostatic-sensitive components that can be damaged if
handled incorrectly. To prevent any electrostatic damage, avoid contact with highly insulating
materials, such as plastic film and synthetic fabrics. Place the product on a conductive surface
and ground yourself in order to discharge any possible static electricity build-up.
To avoid any potential hazards that may cause severe personal injury or damage to the product
during operation, keep all covers and cabinet doors shut.
The following safety symbols are used in this manual:
Warning:
This information is needed to avoid a safety hazard, which might cause bodily
