Safety information
Classification of the safety information
Knowledge of the User Manual
The User Manual for this unit constitutes an integral part of this Service
Manual. For performing servicing activities it is assumed that the reader
has knowledge of the User Manual, especially procedures for installation,
putting into operation, and handling.
Protection from the risk of electric shock
WARNING! The WARNING! safety indication refers to a risk of personal injury.
CAUTION! The CAUTION! safety indication refers to a risk of damage to property.
ATTENTION! The ATTENTION! safety indication refers to a risk which can cause
equipment to become unserviceable.
IMPORTANT! The IMPORTANT! designation indicates application information and
other particularly important information.
WARNING! The supply voltage must match the voltage specified on the rating
plate. Connect the unit / the equipment cart to a properly installed
grounded outlet. Please use the Erbe power cord only; you can find the
REF Numbers in the User Manual of the unit.
For safety reasons, multiple outlets and extension cords should not be
used. If their use is unavoidable, they also must be provided with proper
grounding.
WARNING! Unplug the power cord from the outlet before exchanging parts of the
unit or cleaning it.

replacement fuses of the rating specified on the unit's name plate may
be used. Before resuming operation on the unit have a performance
test conducted by a competent technician (see Service Manual, chapter
"Maintenance and servicing", section "Performance tests").
CAUTION! This unit contains electrostatically sensitive components. Work at an
anti-static workplace while repairing the unit. Wear a grounding arm-
band while working with electrostatically sensitive components. Hold
the circuit boards by their non-conducting corners. Use an anti-static
container for transporting electrostatically sensitive components and
the circuit boards.
ATTENTION! Adjustments, tests, modifications, maintenance and repair work may
only be performed by Erbe or persons trained by Erbe. If the work is not
performed by trained persons, Erbe accepts no liability and warranty
rights become void.
It is recommended that the technical safety check also be performed by
