Safety Guidelines

This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent

damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert

symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are

graded according to the degree of danger.

DANGER

indicates that death or severe personal injury will result if proper precautions are not taken.

WARNING

indicates that death or severe personal injury may result if proper precautions are not taken.

CAUTION

with a safety alert symbol, indicates that minor personal injury can result if proper precautions are not taken.

CAUTION

without a safety alert symbol, indicates that property damage can result if proper precautions are not taken.

NOTICE

indicates that an unintended result or situation can occur if the corresponding information is not taken into

account.

If more than one degree of danger is present, the warning notice representing the highest degree of danger will

be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to

property damage.

Qualified Personnel

The device/system may only be set up and used in conjunction with this documentation. Commissioning and

operation of a device/system may only be performed by qualified personnel. Within the context of the safety notes

in this documentation qualified persons are defined as persons who are authorized to commission, ground and

label devices, systems and circuits in accordance with established safety practices and standards.
