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.

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. You can also nd further information on our website http://www.fmncom.com

2. General instructions

• The compliance with the operating instructions and the instructions for putting the device into operation is also part of the intended use. Every other use is considered as not intended. The manufacturer assumes no liability for damages resulting from such use.

• All connection cables have to be equipped with an earth-connected shielding. The connection cable for the antenna has to be equipped with a

wave impedance of 50 Ohm.

• The manufacturer recommends to mount devices in PCB version into a metal housing.

• Corresponding mechanisms are to be used for the detection of single bit errors during a data transmission (e. g. protocol with creation of check sum).
