2. General and security information
The contactors dealt with in this document are intend-
ed for use with high-voltage systems for special instal-
lations. They are designed and tested in compliance
with the generally recognised state of the art. However,
improper use, operation, handling, maintenance of or
tampering with electric equipment can cause serious
or fatal injury to the user or others, and the appliance or
other property can be damaged.
The operation, maintenance and installation instruc-
tions for the contactors must therefore be strictly fol-
lowed.
Any uncertainties must be clarified and all queries must
include details of the type of device and the serial num-
ber.
Only authorized and trained personnel are allowed to
plan and carry out all mechanical and electrical installa-
tions, transport, commissioning, as well as maintenance
and repair work. This applies to the observation of the
general installation and safety regulations for high-volt-
age systems as well as the proper use of tools approved
for this purpose. Electric equipment requires protection
from moisture and dust during installation and storage.
