4 General Safety Precautions
WARNING
We decline any liability for material damage or personal injury caused by improper use or non-
observance of these safety instructions. In such case any guarantee expires.
WARNING
Connection, commissioning and maintenance must only be carried out by suitably qualified per-
sonnel.
Correct and safe operation of this device depends on proper transport, storage, installation and
connection, as well as careful operation and maintenance.
WARNING
Work on electrical systems should only be performed by trained personnel under the supervision
of a certified electrician in accordance with the appropriate regulations.
Please read and comply with the following notes before assembling and installing the
unit:
l Please ensure that the controller is installed in a clean room. Please ensure that
the central control unit is protected from damaging environmental influences such
as direct sun exposure, operation-dependent vibrations, dust, etc.
l Never install the controller close to heaters and sinks. Avoid the proximity of
sources of electrical or mechanical interferences. If the controller is installed in an
enclosed space such as behind paneling or in small niches, please ensure suf-
ficient ventilation. Please use electrically conducting floor coverings to minimize
electrostatic charges.
l Keep the conditions for ambient temperature and humidity as stated in the tech-
nical data.
l Use a separate electrical circuit with a specially marked fuse (āred") to supply a.c.
voltage to the unit.
l Please ensure that switching off other tools or devices does not disconnect the
electrical circuit to the unit. Attach a note in the cabinet about the location of the
power supply fuse (low-voltage distributor number / mains fuse number). Please
ensure that the fuse is easy to access.
l Please ensure that the cable duct covers the cable entry opening.
l Use only shielded cables with extra-low voltage for all lines leading to the inside of
the controller. Connect the cable shielding to all connection points. Ground cable
shielding only on one side.
l The precautions applicable for CMOS technology are to be applied to activities
involving server circuit boards and soldering.
l Never install a live circuit board.
