responsibility for such actions. If this product is to be used for other
purposes or other substances outside of our guidelines then Gema
Switzerland GmbH should be consulted.

up and wired according to the guidelines for machinery. The
standard "Machine safety" must also be observed.
–Unauthorized modifications to the product exempt the manufacturer
from any liability from resulting damage.
–The relevant accident prevention regulations, as well as other
generally recognized safety regulations, occupational health and
structural regulations are to be observed.
–Furthermore, the country-specific safety regulations also must be
observed.
Product specific security regulations
–This product is a constituent part of the equipment and is therefore
integrated in the system's safety concept.
–If it is to be used in a manner outside the scope of the safety
concept, then corresponding measures must be taken.
–The installation work to be done by the customer must be carried out
according to local regulations.
–It must be ensured, that all components are earthed according to the
local regulations before start-up.

Safety YT05
Special safety regulations
–The horizontal axis may only be switched on and operated after
careful reading of this manual. Incorrect operation of the axis control
unit can lead to accidents, malfunctions or damage to the plant.
WARNING
The power of the horizontal axis is much stronger than that of a
human being!
►All axes must be secured against access during operation (see
local regulations).
►Never stand under the Z carriage when the reciprocator is not
operating!
–It must be noted, that the horizontal axis has to be grounded before
start-up!
–The plugs and sockets of the axis control unit and the power unit of
the vertical axis should only be unplugged when the power supply is
disconnected.
–The connecting cables between the control unit and the horizontal
axis must be laid in such a way, that they cannot be damaged during
axes operation. The movement sequence of the Z axis must be
observed too. Please observe the local safety regulations!
–The travel distance limits of the horizontal axis must always be set
with reference to the side openings of the booth. If an incorrect travel
distance limit is set, this can lead to damage to the vertical axis
and/or the booth!
ATTENTION
During a test run, it must be guaranteed that the unit is not
damaged by the test!
►In particular, the limitations of the stroke range must be observed
(for further information, see chapter “Setting the mechanical travel
distance limits”)
–When repairing the horizontal axis, the axis control unit and the
power pack must be disconnected from the mains according to the
local safety regulations!
–Repairs may only be made by authorized Gema repair centers or by
personnel correspondingly trained by Gema. Unauthorized
conversions and modifications can lead to injuries and damage to
the equipment. The Gema Switzerland GmbH guarantee would no
longer be valid.
–Only original Gema spare parts should be used! The use of spare
parts from other manufacturers will invalidate the Gema guarantee
conditions!
–We point out that the customer himself is responsible for the safe
operation of the equipment. Gema Switzerland GmbH is in no way
responsible for any resulting damage.
For further information, see the more detailed Gema safety
regulations.
