Safety instructions

This system is designed according to the state-of-the-art ac-
cepted safety regulations. However, please note the following
rules:
1. Before setting into operation, please read all appropriate

manuals!

2. Please take notice of internal and state-specific guidelines

and/or rules for the prevention of accidents (e.g. the pro-
fessional association). If necessary ask your responsible
safety representative.

3. Use the system according to the manual’s regulations only.

4. Always leave the manual at hand at the place of work of

the system.

5. Use the system in technically correct conditions only! You

have to eliminate influences immediately, which impair the
security .

6. Please note the loss of warranty and non-liability by unau-

thorized manipulation of the system. You need a written
permission of the Wilh. LAMBRECHT GmbH for changes
of system components. These activities must be operat-
ed by a qualified technician.

7. Prevent the ingress of liquids into the devices without per-

mission.
