ted on how the complete system functions.

•Maintenance work: The technician must be familiar with the use of

operating fluids and their disposal.

Definition of “qualified electrician”

A qualified electrician is a person with appropriate technical educa-

tion, knowledge and experience who can identify and prevent elec-

trical hazards.

2.3 Danger in the event of non‑observance of the safety in-

structions

Non-observance of the safety instructions can result in risk of injury

to persons and damage to product/unit. Non-observance of the

safety instructions will render any claims for damages null and void. In

particular, non-observance can, for example, result in the following

risks:

•Danger to persons due to electrical, mechanical and bacteriological

factors

•Damage to the environment due to leakage of hazardous materials

•Damage to property

•Failure of important product/unit functions

•Failure of required maintenance and repair procedures

2.4 Operator responsibilities

The operator must:

•Provide the installation and operating instructions in a language

which the personnel can understand.
