1. Safety precautions
ATTENTION!
• Do not operate the units in rooms with explosive atmosphere, damp
environments or rooms with aggressive air or increased electromagnetic
requirements.
• Mind the instructions for putting the device into operation.
• Fuse the unit at the voltage supply input UB_IN of the user interface by
means of a fuse (min. 250 mA, max. 1 A).
• In case there is the danger of touching conductive parts due to improper use
of the unit, the power supply has to be disconnected immediately.
• Do not open the unit, only permit repairs by the manufacturer.

Safety precautions
ESD protection measures
Comply with the ESD protection measures according to
DIN EN 61340-5-1/2 when opening the unit (potential equalization
between body and ground of the unit via high-value resistance
(approx. 1 MOhm) e. g. over a usual wrist band).
Read the user manual carefully to be able to use the wealth of features of your
new WZ LSA 70-3.
