3.3 Personnel requirements
All personnel must be persons who can reasonably be expected to work reliably
and conscientiously. Persons whose ability to react is impaired, for example, by
drugs, alcohol or medication, are prohibited from working with the device.
The regulations pertaining to age and occupation applicable at the site of
installation must be observed in the selection of personnel.
WARNING
The device may only be installed, commissioned, and maintained by trained
personnel.
Many dangers, some potentially fatal, are posed by permitting unqualified
personnel to work on the device. They may also result in damage to the device
and to the plant.
 Qualified personnel are specialists who possess the skills required to install,
mount, commission, operate, and repair the device. These people must have
the following qualifications:
● They must have received training and be authorized to switch the variable
speed drive on and off, to ground the device in accordance with safety
standards and to tag the circuits. They are generally people with expertise in
the area of electrical installation or people who work under the supervision of
experts, such as qualified electricians.
● They have to be familiar with all the safety information, installation and
operating instructions contained in this Guide and be trained to perform first
aid.
3.4 Responsibilities of the operating personnel
The variable speed drive is deployed in the commercial/industrial sector. The
operator of the device is therefore subject to the statutory obligations for
occupational health and safety.
In addition to complying with the safety instructions contained in this document, the
operator must also conform to the safety, accident prevention and environmental
protection regulations applicable at the site of installation of the device. The
following conditions in particular apply:
● The operator must become fully acquainted with the relevant occupational
safety regulations and carry out a risk assessment to determine additional
hazards which may arise as a result of the specific working conditions at the
site of installation.
● When assessing the machine's risk in accordance with the respective local
regulations (e.g., EC Machinery Directive), the operator (or machine
manufacturer) must take into account the following residual risks emanating
from the control and drive components of a drive system.
● The operator (or machine manufacturer) must install additional safety
equipment so as to ensure safe operation of the device and the connected
machine.
● The operator must ensure that the area in which the device is installed and
operates is safe. This means that appropriate safety precautions must be taken
and that notices warning of potential hazards must be clearly displayed. It is
particularly important to warn of the potential hazards arising from
electromagnetic fields, and to prohibit the use of mobile telephones.
