SAFETY INSTRUCTIONS
Qualified personnel
Qualified persons are individuals entrusted with the installation, fitting, startup and oper­
ation of the product and with the relevant qualifications for their work.
This includes people who meet at least one of the three following criteria:
S
They have knowledge of the safety equipment and procedures of measurement and
automation systems, and are familiar with them as project personnel.
S
They are operating personnel of measurement or automation systems and have been
instructed on how to handle the machinery. They are familiar with the operation of the
equipment and technologies described in this document.
S
As a commissioning or service engineer, they have successfully completed training on
the repair of automation plants. Moreover, they are authorized to start up, ground and
label circuits and equipment in accordance with safety engineering standards.
Working safely
S
The device must not be directly connected to the power supply system. The supply
voltage must not exceed 30V
DC
.
S
Error messages should only be acknowledged once the cause of the error has been
eradicated and there is no further danger.
S
Automation equipment and devices must be designed to ensure adequate protection
or locking against inadvertent actuation (e.g. access control, password protection,
etc.).
S
For devices operating in networks, safety precautions must be taken in terms of both
hardware and software, so that an open circuit or other interruptions to signal trans­
mission do not result in undefined states or loss of data in the automation device.
S
Following work on settings or password-protected activities, make sure that any con­
trols that may be connected remain in a safe condition until the switching behavior of
the device has been tested.
Additional safety precautions
Additional safety precautions must be taken in plants where malfunctions could cause
major damage, loss of data or even personal injury. You can find details e.g. in the acci­
dent prevention regulations applicable to your particular application.
The performance and scope of supply of the device cover only a small proportion of test
and measuring equipment. Before starting up the device in a plant, first perform a project
planning and risk analysis, taking into account all the safety aspects of measurement
and automation engineering, to minimize residual risk. This particularly concerns the
protection of personnel and equipment. In the event of a fault, appropriate precautions
must produce safe operating conditions.
