2 Safety and protection measures
The following sections stipulate the residual risks associated with the product,
even when used as intended. In order to reduce the risk of personal injuries and
material damage, and to prevent hazardous situations, you must observe the
safety information listed in this section and the warnings in all other sections of
this manual.
2.1 Personal protective equipment
Personal protective equipment (in other sections also referred to as PPE) protects
personnel from occupational safety and health hazards while at work.
Wearing personal protective equipment may be required during work on the
product. Wherever possible, this personal protective equipment is listed in these
instructions for the individual work steps.
However, detailed specifications of the required protective equipment can only
be determined with full knowledge of the system. The required personal protec-
tive equipment should therefore be determined by the user.
2.2 Signs and labels
The following signs are found on the pump.
Over time, labels can become unrecognisable due to dirt or other causes. As a re-
sult, hazards cannot be identified, or necessary operating indications cannot be
followed. Resulting errors can lead to severe injuries or death.
Keep the labels in good, legible condition and replace any damaged labels.
Tab. 2-1 Overview of labels
2.3 Work and danger zone
The danger zone comprises the entire area surrounding the product. The hazards
associated with the product and the danger zone depend on the application and
the installation location. The danger zone should therefore be determined by the
user.
